DevOps generally refers to a collaborative environment among the development and operations teams. It aims to ensure a smooth flow of communication between various teams to make the software development and deployment process as effortless as possible. It involves several tools for automation, containerization, orchestration, etc. However, it’s not the same for every business or company. For example, DevOps for an enterprise looks very different from DevOps for a smaller startup. In the same way, DevOps for mobile app companies i.e. mobile DevOps, also has a unique set of problems and solutions.

In this article, you will learn about how mobile DevOps is different from general DevOps, its key concepts, and best practices.

How Mobile DevOps is Different?

The usual DevOps principles apply to all software types and business environments. However, they may differ in terms of scale, tool sets, and some processes. That said, mobile DevOps is specifically designed for mobile app development and solves challenges unique to mobile applications.

To start with, mobile apps need to be approved by app stores like Google’s Play Store and Apple’s App Store. Moreover, once the app is published, every following update also needs to be approved by the app store. This means, fixing any bugs and making the corrected version available for the end user can take time. Also, deploying the app to app stores requires additional formalities like meeting the right asset requirements and signing certificates. Hence, regular CI/CD practices may not be possible to apply in the case of mobile apps.

Next, mobile apps require extensive testing to make sure they work on all devices with different screen sizes and operating systems (OSs) seamlessly. This can be difficult to maintain as new device models come up every now and then. Moreover, mobile app developers also need to ensure that the app works with any update in the device’s OS.

Security and data privacy is yet another important aspect of mobile apps as mobile devices often contain sensitive data such as personal information or money transactions.

Mobile DevOps Key Concepts

Mobile DevOps follows the key concepts of usual DevOpssuch as…

Continuous Integration (CI): In Mobile DevOps, Continuous Integration involves developers frequently merging their code changes into a shared repository, triggering automated builds and tests.
Continuous Testing: Continuous Testing involves using automation tools to ensure that every code change in a mobile app works smoothly and properly.
Continuous Monitoring: After a mobile app is deployed, Continuous Monitoring tracks its performance, crashes, and user interactions in real-time allowing teams to detect and resolve issues quickly to enhance app stability and user satisfaction.
Continuous Delivery (CD): Continuous Delivery is all about automating the process of building, testing, and getting the mobile app ready for release. This means that new features and fixes are always good to go for deployment to staging or app stores without needing someone to do it manually.
Continuous Deployment: Continuous Deployment takes Continuous Delivery a step further by automatically deploying every code change that passes testing directly to production, allowing for faster mobile app updates, though it still depends on app store review processes for final releases.

Mobile DevOps Best Practices

Automate everything: Automation is one of the key principles of DevOps. It helps save time, cost, and much of manual effort. Moreover, it also minimizes any chance of human error. Automating testing and deployment helps to reduce the time-to-market for apps while maintaining quality and integrity.
Monitoring and feedback: App stores have a public rating feature which is often a mix of negative comments, genuine issues, and praise. That said, developers can use that feedback to improve their app or fix bugs. Monitoring tools should also be used to monitor the app’s performance in real-time to diagnose and resolve issues faster.
Security: The codes and dependencies of the mobile app must be regularly checked for vulnerabilities and loopholes to ensure data privacy and the safety of users. DevSecOps is a term used to refer to a DevOps pipeline where security is prioritized.
Version control: Version control tools like Git help to manage multiple versions of the mobile app and enable team members to collaborate on them.
UI/UX design: Mobile apps should have a responsive design and a user-friendly user interface so that they work smoothly on all device models and screen sizes.

Conclusion

In conclusion, Mobile DevOps brings a tailored approach to app development, addressing unique challenges like app store approvals, extensive device testing, and security. By incorporating key practices such as automation, continuous integration, and monitoring, Mobile DevOps ensures faster, more reliable releases while maintaining high app quality and user satisfaction. As the mobile ecosystem continues to evolve, adopting Mobile DevOps is essential for developers to stay competitive and deliver seamless app experiences to users.

Blue-green Deployment Explained: The Secret to ZERO Downtime

Wed, 25 Sep 2024 03:52:14 +0000

This article talks about what is blue-green deployment and how it helps to reduce downtime to improve end-user experience.

Introduction to Blue-green Deployment

Frequent and quality deployments are a core principle of DevOps. However, whenever you need to deploy a new version, you must stop the current one first. This leads to significant downtime for the end user and can affect customer experience. Moreover, if any bug or error is found after release, it will require additional downtime to withdraw the updated version and switch back to the old one. This process is how newer versions of the application were deployed conventionally.

A modern approach that solves the problem of downtime and time-consuming rollback procedures is blue-green deployment. Although a bit complicated, blue-green deployment requires ‘zero’ downtime and makes rollbacks easier, thus ensuring seamless user experiences.

But how does it work?

How does Blue-green Deployment Work

Blue-green deployment involves 2 production environments:

‘Blue’ environment is the old/active environment.
‘Green’ environment is the newest environment that needs to be deployed.

As per the traditional method, the blue environment should be stopped first and the green environment should be deployed in its place. However, in blue-green deployment, the green environment is deployed alongside the blue one so that both of them run simultaneously. Then, the user traffic is gradually shifted from the blue environment to the green one. Once all of the traffic has been successfully shifted to the green environment, the blue environment is finally withdrawn. Therefore, there occurs no downtime for any user as both the old and the new versions stay active.

The following illustration depicts how traffic is shifted from the blue environment to the green environment…

Image credits: What is Blue/Green Deployment?

But I also mentioned that it makes rolling back easier in case of bugs, right? How does that work?

So, when the traffic is being shifted from the blue environment to the green one, the latter is closely monitored for any signs of errors or bugs. If any of them occurs, whatever traffic that lies in the green environment is shifted back to the blue environment. The green one is then rolled back for redevelopment and retesting. In this way, blue-green deployment makes rolling back easier in case of bugs that might have bypassed the testing phase but are evident only when actual users interact with it.

All the steps involved in blue-green deployment can be summarized as follows…

Image credits: Blue-green deployment

Benefits

The following are the main advantages of blue-green deployment:

Rapid releases: Earlier, development teams had to wait for off-peak times like midnight to deploy new features so that the downtime affects minimum user traffic. But with blue-green deployment, new versions can released spontaneously without any risk of downtime. That said, it helps to achieve continuous delivery (CD).
Easier rollbacks: As discussed before, blue-green deployment makes rolling back updates simpler without requiring any additional downtime. It makes the deployment process even more risk-free.
A/B testing: A major advantage of blue-green deployment is that it allows for A/B testing. For this, a new code is loaded into the blue environment instead of the green one. A part of the traffic (usually 50%) is sent to the green environment while the other half remains in the ‘newer’ blue environment. Then both of these environments are monitored to decide which one works best and appeals to the audience more.
Improved customer experience: Overall, blue-green deployment helps to improve user experience by limiting downtime and providing 24/7 availability.

Challenges & Limitations

Although blue-green deployment sounds ideal, it comes with a few challenges and limitations:

Demanding: Using the blue-green deployment approach can be expensive as it requires you to keep two nearly identical environments active simultaneously. Also, it requires smooth and effortless coordination between the teams and its members.
Set up time: Initially, setting up blue-green deployment can be a time-intensive process and may require many tries before it is perfected.
Complex traffic routing: Moving traffic from one environment to the other (traffic routing) smoothly can be a complex task and may sometimes cause latency issues. Tools like load balancers may have to be used.
Not applicable to all applications: Blue-green deployment is difficult to apply in the case of stateful applications. This is because if a user is active in the blue environment, his/her user session may get interrupted or lost after making the switch to the green environment.

Conclusion

Blue-green deployment is a modern solution that effectively addresses the downtime problem, ensuring a smoother and more reliable user experience. By running two environments in parallel and switching traffic seamlessly between them, it eliminates the need for downtime during updates. It comes with an added advantage of easier rollbacks which makes it suitable for teams looking to improve their deployment efficiency. While it does have its limitations, such as infrastructure costs and setup complexity, the overall benefits make it a powerful strategy for delivering continuous and uninterrupted services.

5 DevOps Mistakes That Could Hurt Your Culture

Fri, 20 Sep 2024 05:22:28 +0000

In this post, we will be listing out the top 5 DevOps mistakes you should avoid to create a smooth and successful DevOps culture.

Top 5 DevOps Mistakes to Avoid

DevOps has revolutionized the way modern software development works. It has brought development and operations teams closer enough to communicate and collaborate effectively toward a common, shared goal. However, as with any novel approach, there are potential pitfalls that can trip you up if you are not careful. Whether you’re new to DevOps or looking to optimize your current infrastructure, avoiding certain common mistakes is crucial to creating a smooth and successful DevOps culture. In this post, we’ll dive into 5 key mistakes that many teams make and provide tips on how to avoid them, to ensure a smooth DevOps journey.

Mistake 1: Inadequate monitoring

Bugs and errors are bound to happen, even with the best developers and tools. That’s why monitoring is crucial for detecting and resolving these issues promptly. It involves continuous collection and analysis of data on system health and performance. Monitoring and observability tools measure various parameters and metrics such as CPU utilization, load speed, and uptime/downtime.

Inadequate monitoring may allow some smaller problems to go unnoticed which may lead to major issues later. Hence, a robust monitoring system is necessary to keep all processes and the infrastructure under check.

Mistake 2: Ignoring automation & tooling

Automation is integral to DevOps culture. It involves using tools that can be programmed to carry out certain repetitive processes without requiring much human interference. Tools can automate tasks like testing, security checking, deploying, backing up, and scaling.

However, many businesses, especially small-scale ones, might avoid using automation for various reasons. Firstly, because automation tools demand high initial costs. Setting up the automated system across the software development process requires time and expert interference. The expert may be hired from outside, or in-house employees may be trained, which, again, takes both time and money. Moreover, legacy systems can also act as an obstacle to adopting automation tools. These systems work well with the business but because of their rigidness and inflexibility, they are difficult to integrate with newer technologies (like automation tools).

However, regardless of these reasons, businesses should consider the long-term benefits of automation as they can help save significant time, cost, and manual workforce.

Mistake 3: Overlooking security

Ignoring security can lead to vulnerabilities that hackers can exploit. There are various techniques to ensure security across the software development process.

DevSecOps refers to an approach where security is prioritized in a DevOps environment by integrating security practices into every step of the DevOps lifecycle. It is also referred to as ‘shifting security to the left’ which means shifting security testing to earlier stages in the development process. It involves using automated security testing tools and continuous monitoring of infrastructure to detect any security threats.

Mistake 4: Prioritizing speed over quality

Smaller and newer businesses may frequently develop and deploy new features, but this may come at the cost of stability and quality. As a result, it can lead to higher failure rates and spending maximum time on fixing bugs and errors. Low-quality services and irrelevant features can hamper customer experience and satisfaction. Ultimately, it can negatively impact the business’s competency in today’s competitive market which prioritizes quality over speed.

Mistake 5: Not understanding what DevOps actually is

Image credits: What Is AWS DevOps? Everything You Need To Know

Many businesses think of DevOps as a technology that a DevOps professional can install and DevOps will turn out magically. However, it’s not that simple. DevOps is an entire culture, a set of practices and philosophies that encourages collaboration between different software development teams. That said, a successful DevOps environment does not necessarily require a separate team. It is, instead, the duty of every team member to contribute to the DevOps culture. The various technologies are only different ways to assist the DevOps philosophy. However, it’s the responsibility of the team members to incorporate and implement these technologies with minimum resistance.

Conclusion

Avoiding these common DevOps mistakes can greatly improve your team’s efficiency and overall success. By focusing on proper monitoring, using automation tools wherever you can, prioritizing security, balancing speed with quality, and understanding that DevOps is more than just tools, you can ensure a smooth and effective DevOps culture. Moreover, DevOps is about continuous improvement, so regularly revisiting and refining your processes is key to staying ahead in today’s fast-paced development environment.

Enterprise DevOps: Why is it Important for Large Businesses

Wed, 18 Sep 2024 04:23:54 +0000

We have already talked about DevOps and DevOps toolchain. In this article we will be discussing DevOps for enterprises or Enterprise DevOps, why is it important, and best practices.

Introduction to Enterprise DevOps

Traditionally, the IT development team and the IT operations team worked in ‘siloed’ i.e. isolated environments. The former focused on developing newer codes as quickly as possible, while the latter tried to deploy these codes without losing the stability of the application. Both of the teams focused entirely on their goal, thus lacking communication. However, this led to slower releases which ultimately affected the business as a whole.

Hence, DevOps was introduced as an approach to bring the two teams close enough for them to collaborate towards a common goal. It can be defined as “…the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity…” (AWS)

Image credits: Enterprise Devops

In smaller businesses, DevOps principles are easier to incorporate as the number of people is less with their scope of work often overlapping with each other. In larger businesses, however, a specialized team is set up to handle specific aspects of the software development process. DevOps becomes much more complicated to execute in this case, thus giving rise to a special term called ‘Enterprise DevOps’ which refers to the implementation of DevOps practices and principles in large-scale organizations or enterprises.

Why is Enterprise DevOps Important

Some of the challenges typical to larger businesses or enterprises that make Enterprise DevOps crucial are as follows:

Large businesses need to release updates frequently to maintain their competitive edge in the market without compromising existing services. This is known as continuous development (CD).
These businesses involve several processes or tasks that may be time-consuming and labor-intensive. Enterprise DevOps helps to automate these tasks, thus saving time, effort, and labor costs.
Bigger companies often involve several teams handling their own set of tasks and responsibilities. So that it doesn’t lead to isolated or ‘siloed’ work environments, enterprise DevOps ensures smooth communication and collaboration between them.
Enterprise DevOps allows for both horizontal and vertical scaling ensuring established companies are ready for unexpected traffic spikes.
Enterprise DevOps helps to detect, diagnose, and resolve issues faster, thus minimizing downtime and ensuring rapid recovery.

Enterprise DevOps Best Practices

Following are some of the best practices for implementing DevOps in an enterprise ennvironment…

Test automation

In traditional software development processes, the application was tested manually once it was completely developed. If any issue was found during this testing (as was the case often), the app had to be sent for resolving and redeveloping again. This led to slower releases and increased time to market.

Test automation refers to automated testing using various tools like Selenium. It allows for continuous testing alongside continuous development. Test automation helps to reduce failure risk and prevent bottlenecks.

Continuous monitoring

While test automation helps to detect anomalies in the application during development, continuous monitoring helps to detect them after deployment. It involves using tools that monitor various application metrics like CPU utilization, network throughput, latency, traffic, etc. Monitoring helps developers detect bugs in real time, thus allowing them time to fix those bugs quickly.

Another term related to monitoring is observability. While monitoring involves continuous collection of data, observability also takes into account the historical data. Hence, observability provides much deeper insights than monitoring. However, although observability has a wider scope, it cannot function without monitoring.

DevSecOps

Security is paramount in an enterprise environment as it involves faster release cycles and multiple stakeholders. Hence, instead of leaving security as an afterthought in the software development process, it should be integrated into every step. This is known as DevSecOps, a DevOps approach that prioritizes security. ‘Shifting security to the left’ is also often used to refer to the early on addressing of security issues during the development process, alongside code writing and testing. DevSecOps can be implemented through automating security testing and continuous monitoring.

Containerization & Microservices

Large enterprises require scalable and flexible infrastructure to deal with sudden spikes in traffic. Microservices architecture is an approach that involves distributing the application into several independent services, each handling a specific business function. It allows the scaling up of individual services with no need to scale the application as a whole. Other complementing technologies include containerization tools like Docker and Kubernetes, and serverless computing.

Standardize toolsets

The market is supplied with multiple tools and technologies for performing the same tasks and procedures. If every individual or team uses a different set of tools, this can createoften create silos and lead to inconsistencies. Hence, standardizing toolsets across teams helps to unify the processes, improve communication and compatibility, and reduce the risk of errors. Moreover, it can help in saving costs and ensuring standardized security tests for all codes.

Conclusion

In the modern world, DevOps is crucial to a business’s success. However, implementing DevOps in larger organizations or enterprises can be difficult due to its huge size and diversity. Enterprise DevOps is a set of DevOps principles and practices specifically designed for these large enterprises. It involves automating all manual tasks to optimize workflows for speed and efficiency. However, it is not just about adopting the latest tools and technologies. It is about creating a culture of transparency, collaboration, and teamwork to work towards a shared goal of business success.

Introduction to Kubernetes: The Go-to Container Orchestration Tool

Fri, 16 Aug 2024 06:27:05 +0000

If you google for Kubernetes, you will be hit with terms like orchestration, containers, and Docker. But what are these things? And how are they related to Kubernetes?

That’s what we are covering in today’s article. Here, you will be learning about Kubernetes and its working, plus how it relates to the terms mentioned above.

Let’s start from the beginning: What are Containers?

Containers are the fundamental units of containerization technology. They are lightweight packages that contain the application code and its dependencies like runtime, libraries, databases, etc. They are highly portable and help improve the speed and efficiency of the development and deployment process. The most popular example of containerization technology is Docker, an open-source platform that uses containers to facilitate the development, testing, and deployment of software.

However, although lightweight, the number of containers can often get out of hand for large-scale companies that provide a variety of services. In this case, managing hundreds and thousands of containers requires a separate tool.

That’s where an orchestration tool like Kubernetes comes in…

What is Kubernetes & Container Orchestration?

AWS defines container orchestration as “…the process of automating the networking and management of containers so you can deploy applications at scale.” As businesses grow, they add more and more services or features to their applications, with each of them having its own container. If a business keeps growing in this way, a time comes when there are thousands of containers that need to work simultaneously to keep the whole application well alive. However, managing such huge numbers of containers manually can be impractical and lead to a variety of problems and inefficiencies. This is why a container orchestration tool is required – to manage the containers.

Kubernetes (also known as K8s) is a container orchestration tool that was originally developed by Google and released as an open-source platform in 2014. Although there are other orchestration tools like Docker Swarm and Mesos as well, Kubernetes is the most popular one and is considered an industry standard.

Kubernetes Architecture: Components and Working

Image credits: The Kubernetes Architecture

Kubernetes cluster: A Kubernetes cluster is a set of nodes (or, in simple terms, computers) that run containerised applications. A cluster consists of 2 kinds of nodes: the master node and several worker nodes.
Nodes: The worker nodes are those that do the actual work of running the applications. The master node, on the other hand, manages these worker nodes by monitoring and scheduling various processes. It is further made up of 3 components: API server, scheduler, and controller manager.
Components of master node: The Application Programming Interface (or API) server acts as the link between the user and the various components of the K8s cluster. It is through this that one interacts with pods, services, and nodes within the cluster. The controller manager simply monitors the performance of the cluster. The scheduler, as the name suggests, schedules the placement of pods and containers based on the current capacity and availability of resources.
Pods: A worker node contains several pods, which are the smallest unit in Kubernetes architecture. Pods can further contain a single container or a group of containers. All the containers in a pod share the same resources and a common IP address. This IP address is used by pods to communicate with each other. Moreover, pods are ‘ephemeral’, which means they can ‘die’ (i.e. fail) in case of application crash or node failure. The backup, in these cases, is provided by services.
Services: Failed pods are quickly replaced or recreated by the master node. However, the newly created pod always comes with a new IP address. Since pod failure happens frequently, the IP address also changes often, which can affect the communication network between the pods. To solve this issue, services act as the permanent IP address of a pod. Even if the pod behind a service changes, the service remains as it is and keeps the communication going.
Kubelet: Kubelet is an important component of the K8s cluster, which is present on every worker node. It monitors and facilitates coordination and communication between all the components (pods and nodes) of the cluster.

Benefits of Using Kubernetes

Kubernetes orchestration helps businesses implement containerization effectively, especially when the containers are in large numbers.
It can be used to automate container deployment and scaling. During peak times, it can automatically scale up the resources (by adding pods) for better performance. During low traffic, it can scale down the resources (by removing pods) to reduce waste.
Kubernetes reduces downtime and ensures the availability of the application 24/7 through load balancing and automatic replacement of failed or unhealthy pods.
It helps to save on costs and resources by automating the various processes mentioned above.
Kubernetes overall complements and supports modern approaches to software development like DevOps and microservices.

Conclusion

Kubernetes has become a game-changer in the world of container orchestration, providing a robust and scalable solution for managing complex applications. Its ability to automate deployment, scaling, and operations across clusters has made it an essential tool for modern DevOps practices. As organisations continue to embrace cloud-native technologies, Kubernetes will play a critical role in enabling more efficient and resilient application management. Whether you’re just starting out or looking to optimise your existing infrastructure, Kubernetes offers the flexibility and power needed to meet the demands of today’s fast-paced tech environment.

An Brief Introduction On NoOps

Shiwani Sharma — Fri, 09 Aug 2024 08:43:13 +0000

An Brief Introduction On NoOps

“NoOps” stands for “No Operations” and is a concept in software development and IT. The idea behind NoOps is to automate the operations side of things so much that a dedicated operations team is hardly needed, or not needed at all. In a NoOps setup, tasks like managing infrastructure, deploying software, and monitoring systems are handled by automated tools and scripts. This lets developers spend more time writing code instead of managing infrastructure.

NoOps is often linked with cloud computing and DevOps, where the infrastructure is managed in such a way that it requires little to no manual intervention. The goal is to create a system that manages and fixes itself through automation, reducing the need for human involvement and minimizing errors.

It’s important to remember that while NoOps aims to cut down on the need for traditional operations roles, it doesn’t mean operations expertise is unnecessary. Instead, it focuses on moving from manual work to automated processes.

Why NoOps?

NoOps, or “No Operations,” is pursued for several key reasons:

NoOps automates repetitive and time-consuming tasks like infrastructure management, software deployment, and system monitoring. This reduces human error and speeds up processes.
With NoOps, developers can focus more on writing and improving code rather than managing infrastructure. This leads to faster software development and deployment, allowing businesses to innovate and adapt quickly.
By minimizing the need for a large operations team and reducing the chances of costly human errors, NoOps can lower operational costs.
Automated processes can easily scale up or down based on demand, making it easier to manage resources in cloud environments without manual intervention.
NoOps aims to create a self-managing, self-healing system that can automatically detect and resolve issues, leading to higher reliability and uptime for applications.
NoOps complements DevOps practices by further integrating development and operations through automation. It streamlines processes and enhances collaboration, helping teams deliver software more efficiently.

Sustainable DevOps: Optimizing DevOps For The Planet

Wed, 07 Aug 2024 06:02:17 +0000

Detail Information About Sustainable DevOps

Introduction & History Of Sustainable DevOps

Sustainable DevOps is a concept that combines the principles of sustainable development with the practices of DevOps. DevOps, a blend of “Development” and “Operations,” is a methodology aimed at improving collaboration between software developers and IT operations. It focuses on automating and integrating the processes of software development and IT operations to increase the speed and reliability of software delivery.

Sustainability in this context refers to practices that ensure long-term environmental, social, and economic health. Sustainable DevOps aims to make the process of developing, deploying, and maintaining software more environmentally friendly, cost-effective, and socially responsible.

DevOps emerged in the late 2000s as a response to the traditional separation between software development and IT operations. This separation often led to inefficiencies and slow release cycles. DevOps sought to break down these silos by fostering a culture of collaboration, continuous integration, and continuous delivery (CI/CD). By the mid-2010s, organizations began to recognize the importance of incorporating sustainability into their DevOps practices.

Environmental impacts of Software Development

You use a variety of software’s and applications throughout the day. Each software drains your mobile’s or PC’s battery at different speeds. To keep your battery and your device working, you need to charge or power them with electricity. Now unless you are getting it from solar panels or windmills, high chances are that the electricity you use comes from burning fossil fuels. These fossil fuels, as you must have read a hundred times in your school, are limited and cause pollution when burnt. In short, the software’s that you are using is directly linked to pollution, or in technical terms, carbon emission.

The carbon footprint of an individual software or the software carbon footprint is affected by the software’s code quality, architecture, network usage, etc.

Moreover, the devices and hardware that runs the software also emits large amounts of carbon during its manufacturing. After their life ends, they are dumped in landfill while only a minimal percentage of them gets recycled. This is called embodied carbon (or embedded carbon) which is the amount carbon emitted during the manufacturing and disposal of a device. This means that even if a hardware is not using much electricity, it has already contributed to the carbon footprint during its manufacturing. An FPT TV and desktop computers have a much higher embodied carbon while a smartphone has the least.

What is Sustainable DevOps?

Sustainable DevOps, also referred to as Green DevOps or DevGreenOps, is a DevOps approach that focuses on reducing the environmental impact of software development processes. In other words, you can say it is an ideology that sees DevOps as the key to reduce the carbon footprint of the IT development industry. It involves the use of eco-friendly DevOps practices and instilling a sense of responsibility among the company’s teams.

In another terms, it refers to the practice of integrating sustainability principles into the DevOps processes, aiming to create software and manage IT infrastructure in an environmentally friendly way. This involves optimizing resource usage, reducing energy consumption, and minimizing the carbon footprint of IT operations.

Sustainable DevOps practices

Improving code efficiency

Poorly written or longer codes can increase the energy consumption of software and ultimately lead to more carbon emissions.

Green coding is defined by Stl Partners as “programming code that has been produced and written in a way that minimizes the energy consumption of software, thereby limiting the potential environmental impact.” Lazy loading (loading only those resources that are required at the moment) and caching mechanisms (locally storing frequently accessed data) are some green coding practices that help to save energy.

Using cloud services

Cloud computing allows businesses to use computing resources (servers, storage, infrastructure, etc.) whenever required without relying on physical hardware. In addition to being cost-efficient, cloud computing has numerous environmental benefits as well.

Firstly, it reduces the need for physical hardware that, as discussed before, reduces carbon emissions. Then, some cloud providers use green data centers that run on renewable energy. Lastly, cloud resources are auto-scalable. This ensures that no extra energy or hardware is wasted while business requirements are also met.

Continuous monitoring

In DevOps, continuous monitoring refers to constant monitoring and analysis of the development and operations processes. But in terms of sustainable DevOps, continuous monitoring refers to constantly checking the environmental impact of software’s instead. It involves tracking parameters like carbon emissions, energy consumption, and resource utilization.

Carbon Footprint, released by Google Cloud in 2022, is a monitoring tool that helps businesses track their carbon emissions based on their Google Cloud platform usage.

Automation

Automation can help in efficient resource utilization and make sure resources are used only when necessary. It can automatically scale up resources (like servers) during peak times and scale down during peak-off times. In this way, it also helps in reducing unnecessary costs. Automated monitoring tools can help monitor carbon and energy efficiency as discussed before. They can also be used to detect anomalies and inefficient codes.

Conclusion

Sustainable DevOps is about making the process of developing and running software more environmentally friendly and responsible. It combines the speed and efficiency of DevOps with sustainable practices like using energy-efficient technology, writing efficient code, and reducing waste. By adopting Sustainable DevOps, organizations can not only improve their software delivery but also help protect the environment and support long-term social and economic health. Embracing these practices benefits everyone—businesses, customers, and the planet.

What are DORA Metrics?

We have already discussed about DevOps culture and a few metrics and KPIs before. In today’s article, we will be focusing on 4 standard metrics provided by DORA and how to improve them.

What are DORA Metrics in DevOps & How to Improve Them?

The aim of DevOps is to improve the software development process through better communication and collaboration between the development and operations teams. DevOps culture has four basic principles as per the CAMS model:

Culture
Automation
Measurement
Sharing

The third principle, that is measurement, is what entails the metrics and Key Performance Indicators (KPIs) used to evaluate the DevOps performance of companies. These metrics and KPIs also help companies find loopholes in their development and deployment process. There are several metrics and KPIs, but four of them have been set as standard by DORA.

Let’s see what is DORA and it’s 4 standard metrics…

What are DORA Metrics?

DevOps Research and Assessment (DORA) is a research program launched by Gene Kim, Jez Humble, and Dr. Nicole Forsgren. It is a team at Google Cloud that “seeks to understand the capabilities that drive software delivery and operations performance.” (DORA)With years of research, DORA has identified 4 key metrics that help to measure the DevOps performance of businesses. These key metrics can be categorized based on what they measure.

The first category measures the throughput (or velocity) which refers to how fast changes are being made. It includes:

Deployment frequency
Lead time for changes

The second one measures stability which refers to the quality of the changes and the ability of the team to fix any failures. It includes:

Change failure rate
Mean time to recovery

Based on these metrics, DORA classifies the DevOps performance of companies into four: Elite, High, Medium and Low. After understanding all the metrics, you can also attempt the DORA Quick Check to evaluate these metrics for your company.

So let’s discuss each one of the metrics and how to improve them one by one…

Deployment frequency

Deployment frequency tells how often new codes are deployed to production. It can be simply calculated by counting the number of codes deployed over a period of time. It can range from multiple times a day (for high-performing teams) to once every 6 months or more (for low-performing teams).

How to improve deployment frequency?

Smaller deployments: When you receive a proposal for change, try to break it down into smaller changes. This makes it look less intimidating and more doable. Moreover, it becomes easy to test with smaller changes and rollback in case of failures.
Automation: Automating manual or repetitive tasks like testing or deploying can help reduce time spent on individual deployments. This allows the workforce to focus on more creative and complex tasks instead, thus improving the frequency of updates.

Change lead time

Change lead time or the lead time for changes indicates the efficiency of the CI/CD pipeline based on how much time it takes for a change to get successfully deployed to production. In other words, it is “the difference in hours between the date and time of the author’s commit and the date and time of the deployment containing that commit.” (Pluralsight)

It can range from less than an hour (for high-performing teams) to more than 6 months (for low-performing teams).

How to reduce change lead time?

Smaller deployments and automation: As said before, smaller batches of codes and automated testing and deployment help speed up the deployment process and reduce change lead time.
Optimize communication: Smooth communication and collaboration help in faster decisions and less delays.

Change failure rate

Change failure percentage or change failure rate (CFR) is the percentage of deployments that lead to failures in production. A ‘change failure’ means any negative impact like crashes, low performance, or security vulnerabilities caused by a change or update. It can be calculated using the following formula:

CFR = (number of failed changes/total number of changes)*100

A CFR lower than 15% is considered good while anywhere between 16 to 30% is considered high. A lower CFR indicates a reliable CI/CD pipeline and effective testing.

How to reduce the change failure rate?

Automated testing: Test automation and code reviewing at every step help to ensure the correctness of codes and reduce human errors.

Mean time to restore service (MTTR)

Also known as failed deployment recovery time, MTTR is the time taken to recover from a partial service interruption or a total failure. It includes the time spent diagnosing and repairing the issue and redeploying the new code. It can be calculated using the following formula:

MTTR = (Total downtime/Number of incidents)*100

It ranges from less than an hour (for high-performing teams) to 6 months (for low-performing teams).

How to reduce MTTR?

Real-time monitoring and alerting systems: Continuous monitoring helps to instantly detect anomalies and resolve them quickly.
Automation: Use automation tools for detecting and resolving faults speedily.
Improve communication: Improve communication between teams to reduce delays and keep everyone updated.
Infrastructure as Code (IaC): IaC improves collaboration and allows easy rollback mechanisms in case the new code does not work.

The above metrics can be summarized using the table given below:

Other Important Metrics & KPIs

Change volume: Change volume measures the amount of changed code against the static (old) code. It helps to determine how impactful the deployed codes are.
Defect escape rate: It measures how frequently defects go unnoticed and escape into production. It indicates the quality of the development and testing processes.
Time to detection: Time to detection, as the name suggests, is the time taken to detect failures. A lower time to detection means effective monitoring and alerting mechanisms.
Deployment success & failure rate: Deployment success rate is the percentage of deployments that do not require rollbacks or hotfixes while deployment failure rate includes those that result in errors.
Customer ticket volume: It is the total number of tickets or alerts raised by the customers.

Conclusion

Measuring your performance is the key to improving it. The four DORA metrics – deployment frequency, change lead time, change failure rate, and mean time to recover – help to quantitatively measure the current performance of your DevOps team. These metrics can be improved mostly through automation and smooth collaboration between teams. Continuous assessment and improvement of these metrics ultimately help to improve customer satisfaction – the goal of all businesses and companies.

Top DevOps Trends Of 2024

Fri, 19 Jul 2024 07:19:53 +0000

5 Popular Trends In DevOps In 2024

DevOps Trends Of 2024 .We have already talked about top 2024 trends in DevOps in our article – https://devopscurry.com/top-trending-best-6-devops-trends-in-2024/#google_vignette

Today we will be listing the most popular and revolutionizing DevOps trends till date.

1. Microservices

Traditional software used a monolithic architecture that had a single codebase operating all its services such as UI, payment processing, customer support, etc. However, because of having a single unified codebase, updating a single service meant accessing the whole codebase. Also, if one of the components was facing an error, it could affect other components or services as well.

This made the development process cumbersome and complex.

Microservice architecture overcomes this drawback by isolating these services so they no longer affect each other. Making individual updates to a service no longer requires releasing a new version of the entire software.

Overall, the microservice architecture is highly reliable and risk-free and helps to improve productivity and save time.

2. Serverless Computing

What does a server do?

A server stores all the data for a particular website or web application and sends this data when requested by the client’s system. Usually, businesses buy physical hardware that acts as their server. But there are some problems with a physical server:

Buying and maintaining the hardware can be expensive and requires physical space.
For growing businesses, additional servers need to be bought to handle the increased traffic on their website.
If there’s a sudden rush in traffic, and the number of servers is not able to keep up, the website will crash.

However, with Serverless computing, businesses need not worry about buying any servers at all. That said, ‘Serverless’ does not mean ‘no servers’ but ‘not buying any servers’.

They only need to take care of the frontend (that is, display) of their website while their serverless provider handles the rest. This has several benefits:
It allows developers to code in any language such as Python, Java, etc.
The serverless provider automatically employs more servers as and when the traffic to the website increases.
The provider does not charge the business based on the number of servers but on the amount of computation. Cloudflare uses a nice analogy to explain this which goes as – “This (serverless computing) is like switching from a cell phone data plan with a monthly fixed limit, to one that only charges for each byte of data that actually gets used.”

Overall, it helps save costs for newer and growing businesses while helping with efficiency and scalability.

3. DevSecOps (Development Security Operations)

In the DevOps approach, the software is tested for security only once the entire development process is completed. But in DevSecOps, every step of the development process is accompanied by security testing. Shift Left and Shift Right are a few more terms related to DevSecOps. Shift Left is the process of checking for security issues in the early developmental stages. Shift Right refers to checking for vulnerabilities once the software is launched as some of them might have bypassed the earlier security checks.

Tools like Static Application Security Testing (SAST) and Dynamic Application Security Testing tools automate the security scanning process to keep the development process going and not stuck.

4. AIOps

AIOps, short for artificial intelligence for IT operations, refers to the use of AI and machine learning (ML) to automate IT operations. It is also known as IT operations analytics (ITOA) or Cognitive Operations.

AI is used for various purposes in the software development and deployment sector:

It is used for detecting anomalies or abnormal behaviors (in network, performance, or security)
It is used to find the root cause of these problems.
It is for analyzing historical data and patterns to predict future trends.
It continuously monitors the network and performance in real time.
It helps to collect data on user experience and interaction.

AIOps saves time and expenses by automating several processes. This allows businesses to focus their workforce on more important and less manual tasks. It also lowers the risk of human error. Lastly, it helps with making strategic and data-driven decisions.

5. GitOps

GitOps is a modern approach to software development and deployment that depends on Git repositories and automation. It is defined as “…a set of practices and tools that rely on Git as the central source of truth for managing software applications and infrastructure.” as per a Medium article by Mistazidane. GitOps uses the Infrastructure as Code (IaC) concept which means storing all the infrastructure configurations as code in the Git repository. The Git repository is where all the codes regarding the infrastructure and a history of all the changes are stored.

The GitOps workflow is as follows:

A developer raises a ‘pull request’ in the Git repository to change the infrastructure.
The other developers or team members can see this request. They can accept this request as it is, add their contributions, or reject it altogether.
Once the request is finalized, it can be automatically deployed through an automated process that removes any inconsistencies or human errors.

GitOps helps improve collaboration among the team and smoothens the development and deployment process. It is also highly reliable as it allows you to ‘roll back’ to the last best version if the new version doesn’t perform as expected.

Conclusion

As we move further into 2024, the landscape of DevOps continues to evolve, driven by emerging technologies and changing business needs. From the rise of AI and machine learning in automating workflows to the increased focus on security and compliance, these trends are reshaping how we approach software development and IT operations. Embracing these trends can lead to more efficient, scalable, and secure practices, ultimately enhancing your organization’s ability to innovate and respond to market demands. Staying informed and adaptable is key to leveraging the full potential of DevOps in this dynamic environment.
