Roles and Responsibilities of a DevOps Professional

Understanding the Role of DevOps is the talk of the town, there has been a lot of curiosity, discussions, brainstorming going in the software industry about it. There is also a lot of literature available online about DevOps, but still many fail to understand what exactly it is. Is it technology? Is it a process?

DevOps is a set of practices that combines both sides of the software world, Development (Dev) and IT operations(Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.

Who is a DevOps Engineer?

The DevOps process is still evolving and making progress every day. As the process is still advancing and making a breakthrough, so is the role of DevOps Engineer. It is often difficult to comprehend the role as it is not confined to a single defined entity. But, to put it into the simplest terms the DevOps Engineer is a cross-functional role, the person works with the developers and Operations team to facilitate the code release in alignment with the CI/CD pipeline.

We frequently encounter this common query as “What does a DevOps engineer do?”, “What is the role of a Devops enigneer”,” What responsibilties does Devops team handle” etc.

So to answer that there is no fixed set of defined roles and resposibilities for a Devops professional, but their roles keep on changing from one organisation to another based on the requirement. However as a part of this post we have tried to cover some of the general expectations from Devops person, which again change on a need basis.

Roles and Responsibilities in the team

The DevOps process is an amalgamation of people of different roles coming together to work on a project as a team. So, the role requires a person who has knowledge of diverse fields. Lets have a look at the responsibilities of a DevOps Engineer:

1. A Software specialist
Oversee the latest technology trends and processes currently in the market. Also, analyze,reserach and implement the new requirements and develops a plan for improvement according to the market trends and customer needs. Someone who had good understanding and experience with the different SDLC phases.

2. Cloud Architect
A Devops engineer also needs to work in a cloud environment, hence experience with public clouds like AWS, Azure,GCP is required.A lso with more and more organizations following the Hybrid cloud and Multi-cloud approaches, the Devops person is supposed to have worked with different public cloud and should be able to architect Multi-cloud solutions.

3. Team Management
Involved in analyzing the issues, prioritizing and delegating the tasks to the team members. The DevOps Engineer should have thorough knowledge and experience of all stages of the product lifecycle. He should be a good team player and also a good leader so that can lead and manage the team in future.

4. Agile expertise
The DevOps role requires a thorough understanding of the software development lifecycle especially Agile Methodology. The DevOps is an extension of agile, so the inside out knowledge of that helps in implementing the DevOps lifecycle efficiently.

5.Technology Enthusiast (Tech Evangelist)
The DevOps is still growing and evolving every day with new technologies and tools.So the team requires a person who can keep a tab on changing trends in the market. Also he should have a keen interest in technology and able to adapt to technology, as and when needed.

6. Automation Expert
Automate the process end-to-end is also one the of DevOps practices. The role requires the DevOps Engineer to learn the required tools which are commonly used in the DevOps practice. Some of the popular tools are Jenkins, Git, Selenium, Docker, Ansible,Terraform.

7. A Handy Programmer
Ability to write and develop applications using coding languages. The DevOps Engineer should possess strong logical skills as the team might need assistance from development to quick fixes in the code. It is good and advisable for a Devops engineer to have familiarity with at least one of the programming languages like Python, Golang,Java etc.

8. Testing/QA skills
The DevOps Engineer role requires the person to have a good understanding of quality assurance. The role might require to occasionally performing some QA activities involving the framework. Understanding of the QA tools is a big plus as it helps to mitigate the problems faced by the QA team.

9. Deployment strategist
The DevOps Engineer should possess a strong knowledge of continuous integration practice. In simpler terms, the aspiring DevOps Engineer should have excellent knowledge of the deployment process. Some of the tasks involved in the deployment process are server configuration, maintenance, fixing integration issues.

10. Support and Maintenance
The DevOps Engineer is not limited to production deployment. To monitor the issues on the live server requires maximum attention. And to make sure that the application is glitch-free, the DevOps Engineer requires excellent troubleshooting skills.

11. Customer Centric approach
The DevOps Engineer at times are also involved in directly interacting with the end-customers and getting requirements from them.Hence a good Devops candidate should have the ability to handle and deal with global customers and get more business and revenue for the company when needed.

12.Security knowledge
Last but definitely not the least it is to ensure that the application and infrastructure is protected from any malicious attack from outside. And for that DevOps security comes into the picture also known as DevSecOps. Several parameters need to be taken into account to build a robust software application. The DevOps Engineer needs to have a stronghold on software infrastructure, cloud security, and other DevSecOps best practices.

Conclusion The DevOps role demands the aspiring Devops to be a `Master of All`. The DevOps is a promising field but requires an in-depth understanding of the software lifecycle, related tools, and the best practices in the market. The field is evolving and can be a great career option.

The procedure of business is developing from facilitating the skill of business to existing some strategic modification that helps to stimulate the speed and growth of business and instantly it provides the ideas to the market. There are some features and pillars or points that procure the bedrock for cloud-native systems that are the Microservices, Containers, Backing services, Automation and the last one is Modern design. Cloud-native is one of the important themes in software development and it is the outlook of software development. It has changed the procedure and the way we understand the operating software product, deploying, developing.

Cloud-native affects the operation of your application, design, deployment and enactment. This provides all this not only operating the prevailing application and many more. Providing the benefit of the cloud computing model, the cloud native is the way to create and operate an application.

What is the Cloud Native Computing Foundation?

CNCF (The Cloud Native Computing Foundation) that is developed in the year 2015 which is an open-source foundation that facilitates the adoption of cloud-native computing and that motive is to organize a society that is vendor irreligious for the developers, IT technology and the service providers to work together as an open-source people.

You can utilize cloud-native computing foundation as open-source software as well as many other technologies to create and deploy applications on some platform-like cloud computing, some of the technologies are microservices, containers, service mesh etc. It also conserves some of the branded technologies and assures them to use them properly for the society elements.

What is Cloud Native Architecture?

It’s an open-source software foundation that consists of some of the big organizations or platforms like Cisco, IBM, Google, VMware, Intel etc. And it’s main function is to be assigned for creating cloud-native computing universal and bearable. Some companies require a software company and it is not necessary of having a software business for that, so for that Cloud Native Computing Foundation is required. Cloud-native permits to work rapidly for all the software and IT companies.

Nine Best Practices for a Successful Devops Implementation in 2023

Fri, 28 Oct 2022 14:12:10 +0000

Successful DevOps Implementation: Nine Best Practices in 2023

The benefits of Devops implementation are clear; organizations that embrace the shift to DevOps release more capabilities, faster releases and experience fewer performance issues.

However despite the obvious advantages, a DevOps transformation isn’t an endeavour to be taken lightly. As Ian Head, research director at Gartner, predicted, “90% of I&O organizations attempting to use DevOps without specifically addressing their cultural foundations will fail.”

So, if your organization has decided to take the plunge and implement DevOps based transformation project. This is an article that will try and help you guide your thoughts on the best practices, as you move ahead on the Devops implementation project.

1. Do not jump the Bandwagon

DevOps is not a magic solution or a magic wand for all the problems that the company is facing. It is a long-term solution for the transformation.
Large programs and larger transformation projects are time-consuming and they take a considerable amount of resources – both time and money. It is important that the organization understands the requirement of a transformation program and lays down the foundational rules for the same.
Automating everything in one shot is always not the priority.
Securing the acceptance of the key organizational POCs forms a crucial part of the program. While internal acceptance is critical, it is also imperative that a dip-stick survey and understanding from the external stakeholders is also needed.

2. No more DevOps engineers as a Role

DevOps was initially introduced and promoted as a software development methodology which will aid agile development process. However, as the days passed the approach transformed itself into a role.
The DevOps Engineer today only manages the infrastructure. For many organizations, implementing DevOps means, scaling up the team of DevOps engineers. This does not help.
If DevOps is maintained as a transformational approach rather than a fancy role or profile, then the enterprises could see a huge success in the implementation of the program.

3. Build a Collaborative Culture

A DevOps team structure requires a change in the way everyone interacts within the organization. Proper communication is essential for a successful DevOps implementation.
With so many departments and teams collaborating and working together to meet a specific goal, good communication is the key to avoid errors and reducing your chances of failures.
Hence one should try to adopt or build a collaborative culture and open communication within teams to ensure the success of the Devops transformation process.

4. Conduct Benchmarking

Before engaging professionals for a transformation program based on the DevOps methodology, any organization must conduct a benchmarking exercise. It helps if these exercises studies multiple things such as number of processes automated, the number of engineers required, the amount of infrastructure needed to scaleup, and much more.
This exercise will not only justify the spending of time and money by the organization, but it will also help arrive at a starting point for the project.

5. Define the Performance metric

Like a science experiment is not fruitful, if it does not have an objective the transformation program will also be not fruitful if there are no performance metrics defined at the beginning.
The relevant project teams involved could work with the relevant stakeholders to arrive at the parameters and then work backward to achieve them through the DevOps based transformation software development methodology.

6. Continuous Monitoring and Feedback loop

This not only helps avoid any crisis but also helps maintain healthy progress in the development process.
Before the DevOps era, many research prove that developers generally did not monitor their application performance in production and assumed that any failure is related to infrastructure on which it is run.So, it is crucial for development teams and operation teams to check and monitor the performance of the application.
Also post monitoring the feedback that you get from internal teams or your customers, also plays a crucial role in DevOps implementation process and is a deciding factor for the success of DevOps transformation.

7. Dashboard automation

An automated dashboard not only helps the engineers keep a track of the SDLC process, but also helps maintain an active database of changes made to the server and database over a period.
This dashboard will give you data with in-depth understanding and provide reports of every operation during the DevOps transformation process.
It also helps to monitor the entire DevOps implementation process along with how effectively the DevOps teams are working together, integration of cloud automation toolchain and an overall platform health status.

8. Getting the right DevOps toolchain

It is important to leverage all the DevOps based tools such as Kubernetes, Docker technology, Jenkins, Git and others. These tools not only give the project manager a sense of control over the project but also help automate mundane tasks.
It is advised that the database technology that is used in a large DevOps project helps the company scale-out and not scaleup.
As per Devops experts, all the toolsets that you choose should be compatible with your system, which is a good configuration management practice.
A good selection of tools helps minimize any conflicts that can occur between development teams and operations.

9. Modularization of Architecture

There are a lot of legacy applications that will change as a part of this transformation project involving DevOps.
So modularization of legacy applications will not only help modernize the environment, but it will also reduce a lot of costly overheads.
Hence moving from a legacy monolithic architecture to a modular Microservices approach will help in the long run and also ensure a successful Devops implementation

While this is an indicative list of the possible best practices to be kept in mind while a Devops transformation project, the actual list of best practices is arrived at based on the current setup of the organisation, level of automation and tools used, collaboration and inter-communication within teams and also volume of the project.

How to pick the best Cloud Partner for your business in 2023

Fri, 19 Mar 2021 13:56:05 +0000

Best Practices to follow when choosing Cloud Vendor

Introduction

The introduction of cloud technology has benefited many companies with fewer expenses and improving operational performance. Implementing a cloud approach and strategies helps the business to deliver digital innovation that has become the influencing factor for the business.

Though many cloud services and providers are offering different features for different sizes and areas of business. But the key concern is How you can choose the right cloud vendor?, that can help you to leverage all its benefits within your budget and meets your business needs.

The absence of a common standard framework or process for assessing Cloud Service Providers (CSPs), combined with the fact that no two CSPs are the same, also complicates the process of selecting the one that’s right for you.

Also the field has a lot of competitors in it, including the big three — Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) — not to forget the local and niche players.

Cloud Trends Across the Globe

Below data has been taken from `Flexera 2020 State of the Cloud Report`

Increase in Public Cloud Adoption : we do see an increase in public cloud adoption YoY, with more and more enterprises trying to get on Cloud or even Multi-cloud models.

Image Source: https://www.flexera.com/blog/industry-trends/trend-of-cloud-computing-2020/

Enterprises are growing their Public Cloud expenditure: Cloud-first policies and cloud migration are at the top of mind for senior IT leaders, particularly in enterprise environments. As a result, enterprises are rapidly increasing their public cloud spend and also workload volumes.

How to choose the right Cloud vendor for your workloads?

The base for choosing the right cloud vendor may vary from organisation to organisation, as each organization has it pwn unique business requirements and needs for the cloud. So firstly, you have to understand the need of your organisation, why you want to go for the cloud, and what type of cloud service you want to avail.

Below we are sharing some of the key points that you might consider while evaluating the cloud vendors for your business needs.

Business requirement

First, you need to understand your business requirement in detail. Then you should look for the list of providers offering that business needs. Each vendor has their set of specifications that they will provide and you can choose the plans accordingly. In this way, you can easily shortlist the providers within your operational cost.

Cloud Vendor Cost

If you are already leveraging cloud services and want to migrate to another cloud platform that can be costly. So choosing the right plan at the start is important. Before opting for any service, check for your infrastructure budget and compare it to the vendor’s pricing plans.

Data Security

Before integrating with any cloud service you have to check how secure is the cloud and understand its data security policy. If you are dealing with crucial data then security is a must and needs to be ensured. If you have a massive amount of data, then the location of the server(DC) also plays an important role to avoid the overhead for uploading and downloading the data.

Technology Advancements

Check whether the cloud provider offers you the latest technology or the technology that is compatible with your business needs. If you want to enroll in the latest technology then you have to make sure that your company has the in-house team well-dipped and trained on that technology.

Support

With the huge amount of data on the cloud, there can be many cases where you might need assistance from the cloud providers regarding any issue. It is better to have a vendor that provides 24X7 support. Cases like migration and deployment required professional assistance or a third-party that can provide you assistance.

Reliability

Before you go for any particular cloud provider you should check its reliability from the past trends. You must be aware of how the cloud vendor can handle unexpected downtime and data recovery during a disaster.

Certifications & Standards

Vendors that comply with recognised global standards and quality frameworks demonstrate an adherence to industry best practices and standards. While standards may not determine which service provider you choose, they can be very helpful in shortlisting potential suppliers.

Factors to help you choose the right Cloud service provider

Many factors drive your choice for choosing the right cloud vendor. But the one who can customize its services as per your business needs is the one to approach. Below are some reasons that will help you in choosing the right provider.

Services offered- As clouds are now offering on-demand services and costing for those services only. Cloud services are not limited just to store your data but also provides you computing solutions for infrastructure and IT networking. It provides hosting different applications on different platforms. So make sure what services you are looking for that will help you in selecting the right cloud provider.
Ensures faster software updates- If you are going for any cloud vendor, they provide you with easy and instant software updates. If any latest update is available for the services or applications that you have opted for will get an update in a few clicks. With cloud services, you will always be up-to-date in terms of the software version.
App performance- Before you choose any cloud provider, make sure that your application will be able to run on that cloud properly. As applications may work differently in some environments and are suitable for a particular architecture. If an organization goes for a third-party, it will surely help in avoiding common mistakes sharing the workload.
Consulting engagements- The consulting services may vary from vendor to vendor. Some cloud vendors ensure that they provide the best-consulting arrangement for their clients. It is one of the most important factors that allows the organization to choose their vendors. It can be a crucial factor for organizations if they lack in-house expertise for providing consulting support for your applications. Having a third-party at your disposal can help you bridge the knowledge gap.
Disaster recovery- With a lot of data and workload, it may be possible that cloud services may hinder and lead to disaster situations. Thus organizations want their cloud service provider to provide real-time disaster recovery solutions. Organizations should focus on this factor and investigate the process in action offered by the providers during data and resource recovery.
Multi-Cloud facility- With the advancement in technology and the need for different platforms to host applications that require different infrastructure requirements for various cloud vendors. It allows the organization to migrate easily from one environment to another with great ease. In those cases, incorporating a multi-cloud solution to your business can be the best fit and provides you with a lot of various features.
Service levels- If you are opting for a cloud service provider then you must look into the SLA they are providing. You must have a clear contractual relationship with your cloud service provider. You should consider the security of your data being hosted whether it has GDPR policies in place or not. You must have a legal contract that will back you up in case of any mismanagement.
Easy manageability- before choosing your cloud provider, you have to make sure that it allows you for easy management and integration of services and applications you have at your end. As different providers support different tools and can integrate with different services. Also, you have to focus on how much time and efforts are required by your team to manage large scale applications on the cloud infrastructure. This can be an important deciding factor for your organization.
Scalability- for any organization, the data and demand for the resources may vary from time to time. There may be situations when the company will no longer require particular resources from the cloud provider. Then the cloud provider will be able to de-provision those resources and ensure easy scalability during the changing company demands. Also, in case of rising storage or resource demand, the cloud provider will be able to allocate those features at that instant.
Easy workload- it is a good option to choose a cloud service provider that will handle everything from the network, infrastructure to handling applications within a cloud infrastructure. It is more efficient than to have a team at your end and get it managed from a third party without posing a workload on your team. So look for all these facilities before choosing the cloud provider.

Conclusion

While the above points, might not give you all the information you need, but they can help you build a solid analytical framework to use when you are determining which Cloud vendor you should trust with your data and applications. You can even add granularity by doing a thorough analysis of your organization’s needs and requirements to discover additional factors that will help you make an informed decision.

Also we should think about long-term to avoid lock-in – avoidance of proprietary technologies and a clearly defined exit strategy to avoid a lot of headaches down the line.

DevOps 2021: Diving into Azure DevOps

What is Azure DevOps?

We know that DevOps is a practice that helps in bridging the gap between the developers and IT operations that enhance the overall development lifecycle. But what if we implement the DevOps approach to a cloud? It is where we use Azure DevOps to fulfill the need for DevOps needs to the cloud.

Azure DevOps is a Software as a Service (SaaS) from Microsoft, which offers an end-to-end DevOps toolchain to develop and deploy applications. It works with other available tools to orchestrate the DevOps toolchain. Many organizations have implemented Azure DevOps that fit their market needs irrespective of the language, platform, or cloud. Azure DevOps provides a flexible platform, platform, and cloud-agnostic.

Azure DevOps was launched in October 2018, but it is not a new product for the Devops ecosystem. Its presence can be traced back to the Microsoft visual studio team services (VSTS) in 2006. Azure DevOps comes with a new feature set that is now used by millions of users.

Azure DevOps has a lot of inbuilt functionality that allows teams to get up and running with managing their project and automating their workflows to increase productivity with a very short initial learning curve.

Azure DevOps is simply a suite of SaaS services, consisting of Azure Boards, Azure Pipelines, Azure Repos, Azure Test Plans, and Azure Artifacts — providing teams with the feature parity of tools like Jenkins, CircleCI, Octopus Deploy and others. Keeping in mind the fact that Azure DevOps also integrates and supports many providers, 3rd party tools and services, ready out-of-the-box, organisations can either use all those services or use what they need to achieve their goals.

Migrating to Cloud: Follow the 6R’s of Cloud Migration

What is Cloud Migration?

Technology and time go hand in hand. Before the cloud era, we had a giant hardware system that required high maintenance and significant capital. But with time the technology advances and we got introduced to an entirely new concept of Cloud computing. Although it also requires maintenance and capital the benefits are innumerable. One such advantage is that it is beneficial for all sizes of enterprises.

Migration is a process of transitioning from on-premise or existing cloud infrastructure to a new cloud environment. You can follow certain strategies to easily migrate on the cloud.

Benefits of Cloud Migration

In case, the application you are using for your business is flourishing and you are experiencing a sudden surge in traffic. With this increased demand, the resource requirement increases. So in this case look nowhere and go for a cloud-based solution for the application.
The client always comes first and when the end-user wants a better performing application. Cloud is an all-time solution, migrating to the cloud gives reduced innumerable benefits with better performance and at a reduced cost.
One of the main advantages of the cloud is that it’s easily scalable. Storage issues can be easily managed with a cloud-based application solution.
With the teams scattered across the globe, with cloud options world seems to be a global village. It allows the employees to work as a global team through internet solutions.
Most of the cloud vendors also offer out-of-the-box monitoring to keep a check at your applications and cloud infrastructure.
With Cloud you also get backup and logging services which are extremely important, especially if you need to perform disaster recovery from an outage and see where things went wrong.

This post outlines 6 different migration strategies the customers implement to migrate applications to the cloud. Application migration is a tricky job; it requires meticulous planning to achieve the desired results.

The organization needs to ponder upon various factors before moving the application to the cloud. Understanding the complexity of the application is the first step to the process. It involves determining which part of the application needs to migrate first and in which order, what are the inter-dependencies that need to be taken care of, the existing license agreements, etc.

The 6Rs of Cloud Migration

1R Rehost

The method involves maintaining the data, business logic of the application across architectures. The technique is carried out when organizations want migration with very little changes.

This technique is also known as “lift-and-shift”. It usually happens when a legacy application needs to be modified to meet certain business requirements.

An organization was able to save 30% of the application costs just by rehosting. Some of the rehosting tools are AWS VM Import/Export, CloudEndure Migration.

2R Re-Platform

This method involves making a few modifications here and there to achieve cloud migration. The minor changes would involve migrating to a different database like RDBMS for instance.

It does not involve any change in the core architecture of the application. The technique is known as “lift-tinker-and-shift”.

3R Repurchase

As the name suggests the migration involves purchasing new products to facilitate the changes in cloud architecture. However, this technique would work only for applications already on the cloud. For this, the organization needs to identify the legacy application and compares it with a cloud based application available in the market.

This way they would find several applications that solve the purpose with better features. Some of the common trends observed in the market are moving a CMS to Drupal, a CRM to salesforce applications.

4R Refactor

This technique would require a complete alteration to the very core of the application. It is often done when organizations need very strong cloud features for the native application.

The technique is also called as Re-architect. This might also include transitioning of applications to microservices architecture from a monolith. Such drastic transitions require a considerable amount of money, time, and the risk involved is also pretty much high. But this method would prove highly beneficial in long run.

5R Retire

Sometimes the application does not require an overhaul of the architecture; it just needs scraping the redundant processes, services to make applications perform efficiently. To fulfill this, few things need to be taken into consideration
Go through the project to identify unessential parts of the application. Scraping off the unnecessary services, processes will result in cost reduction.
There might be some plan to close the application or merge with the existing project. This would require the application to shut down completely.

6R Retain

The cloud migration is not limited to just scraping the old processes, services, and tools. It also takes into consideration the resources that need to be retained in the process. This would save effort and time. There could be several reasons to retain the resources
The organization’s business principally revolves around existing applications.
The legacy application does not fully support cloud architecture.
The application is working perfectly and does not require new enhancement or modifications.

Conclusion

Cloud application migration isn’t an easy decision to take and it bears a direct effect on various other components in the organisation. There will always be an element of compromise and risk hence It is critical to be pragmatic, be clear on your goals, and make decisions aligned with core objectives. Optimization should be the key factor for any cloud migration decision within an organisation.

Azure Cloud ; This is the third and the last part of our three part series on Azure Cloud services. You can read the first two parts here: Part1 , Part2

Azure Services Glossary

Azure DocumentDB

Azure DocumentDB is a Database-as-a-service NoSQL Document. It uses the JSON data format for storing and querying documents.
Azure DocumentDB offers a NoSQL database using JSON documents that has the benefits of Azure and cloud.
It does have several PaaS (Platform-as-a-Service) features. DocumentDB is a fully-managed NoSQL database.
It is easy to scale-out DocumentDB to meet your data, application, and business requirements.

Azure Fault Domain

Azure Fault Domain describes a group of virtual machines that share a common power source and network switch. When you place your VMs in an availability set, Azure guarantees to spread them across fault and update domains.
VMs spread over 3 fault domains. Each fault domain shares a power supply and a network switch. If the fault domain has a failure, all the resources in the fault domain will become unavailable.

Azure Image

Azure Image is used to create multiple VMs. One managed image supports up to 20 simultaneous deployments.
If you want to create more than 20 VMs at the same time, you may use a shared image galleries image configured within one replica.

Azure Limits

Azure resources manager (ARM) commands limits and quotas on how many resources of each type can be provisioned per subscription.
You can estimate your costs and limits by using the pricing calculator. Some services have adjustable limits and some don’t.
If you want to raise the limit above the default limit, that is also possible using the online customer support.

Azure Region

Azure service is available worldwide. So it’s a good idea to choose the best region for your needs. It depends on technical and regulatory factors: service capabilities, data residency, compliance requirements, and latency.
Each zone in the Azure Region is a separate Datacenter.
Each zone has a separate power source, networking, cooling, etc. There are 60+ regions in Microsoft Azure.

Azure Resource

A resource in Azure is a manageable item available through Azure. Some examples of Resouces are Virtual Machines, storage accounts, databases, virtual networks, and web apps. A JSON file that defines one or more resources to deploy to a resource group is called Resource manager template.
Azure Resource Manager (ARM) is the service used to provision resources in Azure subscription.

Azure Resource Group

Azure Resource Group is a container that related resources for an Azure solution. It contains those resources that you want to manage as a group.
All resources in a group share the same lifecycle. You can update and delete them on one go.
Each resource can exist in only one resource group. Resources can be added or deleted anytime from a resource group.
You can also apply tags to a resource group. Portal, PowerShell, Azure CLI, or Azure Resources Manager(ARM) can be used to create a resource group.

Azure Roles

It’s a collection of permissions.
A role in Azure defines lists of operations that can be performed – like read, write, and delete. Azure role-based access control (RABC) helps in managing these roles.
You can decide who can access Azure resources, what they can do with the resources, and what areas they can access.
Roles can be high-level like an owner or can be specific like virtual machine leader.

Azure Shared Access Signature (SAS)

It provides secure access to resources in your storage account without discrediting the data security.
You can control how a client can access your data with the help of SAS. It includes control over what resources clients can access, what permissions they have, and how long the SAS is valid.
There are 3 types of SAS in Azure: User Delegation SAS, Service SAS, and Account SAS.

Azure Storage Account

Azure Storage Account contains data objects like blobs, files, queues, tables, and disks.
In short, it contains all of the storage data objects. Storage Account gives a unique namespace for your Azure Storage Data.
You can access this data from anywhere using HTTP or HTTPS. Azure Storage Account offers various types.
Some of them are general-purpose v2 accounts, general-purpose v1 accounts, BlockBlobStorage accounts, FileStorage accounts, and BlobStorage accounts.

Azure Subscription

An Azure Subscription is linked to a single account. To take the advantage of Azure’s cloud services, it is necessary to have an Azure subscription.
There are 3 types of Azure subscriptions: Free, Pay-as-you-go, and Members offers.
A free account provides unlimited access to Azure services for 30 days with a $20 credit. The pay-as-you-go will let you pay for the services/resources that are used monthly. The members offers do have many further types.

Azure Tags

Tags consist of names and values. You can use Azure tags to organize Azure resources.
Tags can be applied to your Azure resources, resource groups, and subscriptions to logically organize them.
Tag names are case-sensitive for operations. To apply tags to a resource, you must have access to write to Microsoft.Resources/tags.

DevOps 2021: Paving your way into SRE

Namrata Joshi — Mon, 09 Nov 2020 08:53:17 +0000

To be or Not to be: Exploring SRE as a Career in 2021

Ever considered becoming an SRE, if you’re looking forward to playing a challenging yet in-demand role in the DevOps space. SRE or Site Reliability Engineering was a term coined first at Google in 2003 by Benjamin Treynor Sloss, VP of engineering at Google, way before the DevOps. Site Reliability Engineering creates a bridge between development & operations by applying a software engineering mindset to system administration topics.

Eventually, SRE has became a full-fledged IT profile, which aims at building automated solutions for operations team such as on-call monitoring, performance and capacity planning, and backup and disaster recovery plan. However at its core, SRE is an implementation of the DevOps paradigm.

So in this post we have tried outlining What is SRE, its key benefits, and also what is the current demand and potential future for the SRE role.

SRE and DevOps

If we consider the traditional definition of DevOps – it is an environment where the development (devs) and operation (ops) work altogether intending to be able to release software faster at great stability.

Whereas SRE aims at developing automated solutions for operational performance, capacity planning & disaster response. Hence, SRE complements other core DevOps practices like continuous delivery & infrastructure automation.

“Site reliability engineers create a bridge between development and operations by applying a software engineering mindset to system administration topics.”

Picture Courtsey: Alice Goldfuss from https://blog.alicegoldfuss.com/how-to-get-into-sre/

SRE as a career- What does a Site Reliability Engineer do?

A Site Reliability Engineer works with operation along with developing systems & software that help to increase site reliability & performance.

So, the ultimate goal of SRE is to automate their way out of a job, as per Google. Google gives a lot of emphasis on SREs to not spend more than 50% of their time on operations & consider any violation of this rule as a sign of system ill-health. As long as you have a strong foundation in software or system engineering, you can consider becoming an SRE.

It is also essential to have a strong incentive for improving & automation. System engineers who want to improve their programming skills & software engineers who want to learn how to manage large-scale systems are perfect candidates for the role of an SRE. This role will allow you to gain a system-wide view.

The role of the SRE can be fun & exciting when the application architecture & technology decisions allow for scalable stateless solutions. Moreover, you can be updated with the latest trends in the DevOps world. It’s a great way to expand your knowledge & skills in high-demand areas like continuous delivery, infrastructure automation & release engineering. This role is extremely creative, stimulating & technically challenging.

How has the SRE role evolved in the last few years?

Twenty years ago, we did not have multiple regions, each containing hundreds of thousands of physical as well as virtual machines. There were no thousands of microservices creating complex software. No service dependency chains were working on a reliable network & hardware working with third-party providers, APIs & vendors.

Now, we need a way to manage these complexities at a faster pace. Google was the first company to really start operating at an internal scale. They created the concept of a new type of engineering to help manage this complexity & ensure reliability. This engineer is called an SRE. But SREs certainly have existed for decades in many different forms. For example, disaster recovery and production testers.

The demand for SREs grew as companies went on to try cloud-native. SREs were required to work in production & operations, with a focus on automation & observability. As the systems became distributed, this role has evolved with time. The role of an SRE evolved from just shoring up uptime to a relationship broker who has viewed into the organization, wide systems & problem-solving. As the demand grows, SREs become those people who can work across the company.

An SRE is someone good at communication as well as prioritization. Site Reliability Engineering is an offshoot of the DevOps culture. SRE is focused on the external value the company can reliably offer customers. While DevOps is more about internally increasing velocity. In conclusion, SRE has been around since forever, but certainly, it’s growing and in-demand. Any size organization can benefit from a good SRE and service level objectives.

The current demand for SRE

An SRE is expected to juggle between networking, security, system administration, hardware & anything else that could possibly make your infrastructure unstable. Hence a SRE can also be called DevOps specialist.

A SRE should know about both software development & system infrastructure. They are in charge of making sure that the website & applications are loading, which is highly critical.

That is why SREs are among the highest-paid in the industry. They also rank among the ones with the most coding experience and it takes hard work & time to get there. SREs job satisfaction is among the highest in the industry, as they have an interesting job with high pay.

SREs rank in the top three of the ones NOT actively looking for a job. SRE professionals are among the most wanted in the tech industry. 33% of IT leaders are having a hard time hiring a good SRE. SREs are 30 times more likely to be men than women. But there are more women than men in this field.

SREs are typically found at high-performing tech companies that have large data centers & complex technical challenges. Their roles can be inspiring from both a financial & workplace culture perspective. SREs are ruling the tech world & more of them are highly in demand.

Future Growth of SRE

Site Reliability Engineers have a great & promising future. SRE is one of the most buzzed skills in the IT industry. With automation & observability becoming a key feature for more efficient & rapid deployment, an SRE job profile will be one of the most demanding in the coming years.

The post-pandemic environment has resulted in a major shift in where SREs will be located. 50% of SREs will be working remotely post covid-19, as compared to only 19% before the pandemic. Moreover, the SRE concept has been embraced by major internet companies like DropBox, Netflix & Airbnb.

The SRE community now even has its conference called SREcon. While we await the milestone, it’s not too soon to consider the implications of the SRE discipline in each & every organization.

Benefits of SRE (Site Reliability Engineering)  

1. Fills the gap between developers and operations
SRE encourages DevOps culture. Hence, SRE fits perfectly in the gap between developers & sysadmins. The entire engineering team is equally responsible for facilitating a reliable and quick CI/CD pipeline.

SRE can draw attention to the areas for improvement in the release pipeline. Meantime, it also creates rules around the culture of on-call availability & incident response that encourages everyone to be more accountable.

2. Focus on Error-budget and SLOs
The main focus of the SRE approach is the SLO for the application or service that is being run by the SRE team. The product manager has to choose an appropriate SLO that gives enough margin of possible downtime to cover unforeseen problems. The SLO approach also drives the adoption of synthetic transaction monitoring, which is great practice for customer-facing systems.

If the product manager working with an SRE team is unhappy with the restrictions. On deploying new features, he/she can either redefine the SLO or put more effort into operational aspects of the software.

3 Remove Bugs before they hurt end-users
Bugs and issues can often go unnoticed when the complete focus is on development speed. If the operation team does not notice them, it may cause significant delays and downtime. Eventually, this will leave the end-users unsatisfied.

SRE works proactively to notice and solve the errors as soon as possible.their performance metrics, combined with their high-level perspective, enable them to find & fix issues during production with a great degree of accuracy. This is a quite effective approach than traditional operations. SRE will also ensure that there are practices for tasks like incident responses, cross-departmental collaboration, and many more to make sure other teams can support them effectively.

4 Improved Metrics reporting
One of the most prominent benefits of SRE is clarity. SRE utilizes pertinent metrics of bugs, productivity, efficiency, etc. they can also translate these measurements in terms of their impact on more tangible elements.

SRE highlights areas of improvement at multiple stages of a development & operations pipeline with a high level of clarity it offers. SRE expert will also observe the relationship between different teams, departments & services for the sake of increasing communication & collaboration.

5 Creates Observability into service health
SRE teams spend their time dabbling in a multitude of different areas of an organization’s systems. SRE experts have the greatest understanding of how everything in the system is connected.

Hence, they know the best way to track logs and traces across disparate services & depict a holistic approach to system health. If any incident happens, the observability is already there so on-call responders can find the context they need.

Conclusion

So you too can make a career shift into an SRE role, regardless of your background in software engineering, as long as you have solid foundations in it and a strong passion for improving and automating the systems around you.

If you are a Systems engineer and want to work on your programming skills, or if you are a Software guy and want to learn about working with large-scale systems, this SRE profile is apt for you. Deepening your knowledge in both areas will give you a competitive edge and more flexibility for the future.

( Azure Cloud)A look at Azure Cloud terminology – Part 2

Namrata Joshi — Tue, 27 Oct 2020 13:49:02 +0000

Azure Cloud Services Overview (Glossary Part 2)

Microsoft Azure Cloud is a set of cloud services taking over the internet to help your company in better management. Many a times people ask what is Azure Cloud in DevOps? Azure offers a bunch of services and tools to help the DevOps team to do their jobs in a better way.

This is the second post in our three part series on Azure cloud terminology. You can check the part one here.

Azure Services Glossary

Azure Functions

Azure Functions are a serverless compute service that allows you to run event-triggered code without managing the infrastructure. It can be built and developed without any additional setup, deploy, and operate in the cloud.
Azure Functions are used to achieve decoupling, high throughput, reusability, and shared.
It’s a separate App service that runs in the App Service Plan. Every function can be invoked using the configured trigger.

Azure Event Grid

Azure Event Grid provides the infrastructure for event-driven computing. The focus here is on events that notify that something has happened. It has built-in support for events coming from Azure services. So it automatically sends messages through Event Grid.
It is used to maximize availability by natively spreading across multiple fault domains in every region.

Azure Service Bus

It is a reliable cloud Messaging-as-a-Service (MaaS). Azure Service Bus will help to decouple the applications from each other, distribute messages to multiple independent back-end systems.
It will also protect your applications from temporary spikes in traffic.
Azure Service Bus Queues allows one-way communication. Whereas Relays provide bi-directional communication.

Azure Storage

Azure storage offers durable storage in the cloud that allows you to store tables, blobs, and message queues.
You can access this storage through HTTP. It is possible to create your own client.
Azure Storage is cost-effective as you will have to pay only for what you need. There is a client library by Azure, but you can also create your client.

Azure Internet of Things (IoT)

It is a cloud service that connects, monitors, and controls billions of IoT assets.
Azure IoT is made up of a circuit board with sensors attached. It will connect to the internet using WiFi.
You can choose from a variety of devices for your solution. IoT devices are pretty different from browsers and mobile apps.

Azure Container Service

It’s a cloud-based container deployment and management service. It supports open-source tools and technologies for container and its orchestration.
It is a flexible, open-source, and simple service to run your container applications in the cloud. You can deploy your container-based applications on a framework with just a few clicks.
The framework is designed to help manage the container’s complexity deployed at a scale in production. Azure Container Service will offer two options to choose from popular orchestration engines: DC/OS or Docker Swarm.

Azure Cognitive Service

Azure Cognitive Service provides a family of AI Services Cognitive APIs for the developers. There isn’t a need to be an expert in machine-learning.
It will let you build apps with powerful algorithms using a few lines of code.
Azure Cognitive Service allows you to deploy Cognitive Services anywhere from the cloud. They work over various devices and platforms like iOS, Android, and Windows.

Azure Container Registry

Azure Container Registry is a registry of Docker and Open Container Initiative (OCI) images. It supports all OCI artifacts.
There are various methods to deploy Azure Contain Registry. The easiest method is using the Azure Portal.
With features like Geo-Registry, it is possible to manage a single registry over multiple regions. It provides integrated security with Azure Active Directory (AD).
Azure Contain Registry handles private Docker images as well as related content formats to provide fast, scalable retriever of container workloads.

Azure Application Insights

Azure Application Insights is a feature of Azure Monitor. It’s an Application Performance Management (APM) service for web developers that supports multiple platforms. It is mainly used by DevOps professionals.
It will automatically detect performance exceptions. It also includes analytics tools to help you diagnose the issues.
To enable Application Insights, you can install an SDK in your application or use Application Insights Agent.

Azure Key Vault

As the name suggests, the Azure Key Vault is a tool to store and access secrets in a protected way. A secret could by anything confidential. Such as API keys, passwords, or certificates.
To do any operations with Keyo Vault, you need to authenticate it first.
There are three ways for that: Managed identities for Azure resources, Service principal and certificate, and Service principal and secret.
Azure Key Vault provides the benefits of a Hardware Security Model (HSM) without the headache of managing it.

So this is the second part of our three part series on Azure Cloud services. Do feel free to share your views and thoughts with us in comments.
