DevOps Vs Agile

If you want to learn more about this topic (DevOps VS Agile), we have a separate blog for the same reference link https://devopscurry.com/devops-vs-agile-understanding-the-difference/

What is DevOps ?

A Process that integrates IT operations, practice, tools, software development And contributes the outstanding characteristics of software with the endless delivery. It characterizes the take on the renewal of programmable infrastructure and expenditure, software development, industrialization. In a company, it stimulates alliance and transmission.

DevOps have some procedures such as the CI/CD tool (Continuous Integration/ Continuous Delivery) with an intensity of task automation. Microservice, Container, and Executing together with the DevOps methodologies. Though it is clear that it has some methodologies, it is not a technology. The two words define DevOps (software development and Operations) and in other words, you can say the assortment of software development and operation is known as DevOps.

It enhances the speed and quality of the application that has been delivering to an enormous extent and that’s why it’s becoming more prominent for the organization. It provides you with the faster speed, security for your code, delivered quickly, these are some of the important features of using DevOps.

What is Agile ?

In the development process of Agile, the product cuts into several minor portions and blends them for the definitive testing. It comes with the management quality and inspired the adoption that stimulates self-organization, great teamwork and last not least accountability. The exhibition of methodologies and the collection of extreme Programming, the scrum that utilizes by the developer is Agile.

Some of the main targets of Agile development is the discussion of the tools and the process and taking the point from individuals and with the entire team. The other point is it concentrates on the constant changes and it targets software development.

What is AgileOps?

AgileOps is a short abbreviation of Agile operations. A software development methodology that builds all the DevOps techniques & helps the organization with their operations quickly and flexibly.

In other terms, Agile plays a central role that helps the developer and operations and also helps to work with the whole organization, data analysts, and business leaders. Agile is a method of software development that collect all the provisions and after that build, test, and release the overall solution. A methodology that helps the organization for becoming more responsible & doing the changes by wiping out some of the work of software development in tiny parts and have to finishes this work more efficiently and quickly is called AgileOps.

Definition Of AgileOps As Per Wikipedia: Agile software development is the mindset for developing software that derives from values agreed upon by The Agile Alliance, a group of 17 software practitioners in 2001. As documented in their Manifesto for Agile Software Development the practitioners value.

Benefits /Advantages of Agile

Some of the advantage are discussed below:

Client Satisfaction: As the client is involved in the development process, the client can share their priorities with the development team and get all the information. This interaction helps to decrease the complication between the development and client about their provided and wanted services.

Increasing the graph of production: Agile utilizes the resources very well and improves the production from them. The users air the developers were targeted on their factoring and moving forward. This will help in increasing the graph of production.

The amount of Risk Decreased: The developer put the better version on the work by that way the number of risks decreases. The team can handle the issues quickly and easily solve them.

Having good Communication: The client has the interaction with the developer team, so there is no gap between the customer wants and requirements.

Reasonable Visibility: In the process of completing the application, a client can give their acknowledgement and opinion.

Difference Between the DevOps and Agile

S.No.	DevOps	Agile
01	DevOps targeted on delivery and regular testing.	Agile targets constant changes.
02	The team have different level of skill-set	The team has the same level of skill-set.
03	Having several department with different level of skill-set	Whole the team works together with the same level of skill set having less number of teams.
04	Some of the tools they are working with are Slack,Trello, Kanboard, Active Collab etc.	Some of the tools they are working with are Docker, Jenkins, GitLab, OpenStack etc.
05	Due to the automation testing the quality of production is good with low risk.	Later each ride, when the product quality increases, the risk decreases.
06	Motivates the team and gives the feedback for the improvement and the fastest delivery.	Products are made according to the client’s satisfaction.
07	It is utilized on the side of the engineering process.	For the project, any department can help them.

DevOps vs Agile – Similarities

Agile and DevOps both have some similar factors which as discussed below:

Both giving the benefit on the productivity of an Organizations: Agile and DevOps both emphasis company productivity. Agile pushes DevOps for the fastest work and DevOps Pushes Agile to be intensive.

Accepting the narrow Philosophies: In a comprehensive amount, both DevOps and Agile executed the narrow Philosophies.

Collaboration Procedure: Both Agile and DevOps are delivered end to end and bring in collaboration with each other to make the process of tools and data easy and effective.

Conclusion

While DevOps and Agile share common goals of enhancing collaboration, increasing efficiency, and delivering higher quality software, they approach these goals from different angles. Agile focuses on iterative development, customer feedback, and flexible responses to change within the development process. In contrast, DevOps emphasizes the end-to-end automation and integration of development and operations, aiming to streamline the entire software delivery lifecycle.

Stages Of AgileOps Cycle

Image Credit:https://www.analyticssteps.com/blogs/what-agile-software-development

As you can see in the above given images, there are six stages of AgileOps Cycle (Meeting, Planning, Designing, Practice, Testing and last one is Evaluate). Now you can go a deeper insights of each stages as described below:

Meet

The first stage of the Agile cycle is meeting. Here, all the stakeholders meet together to solve the problem of what they are facing. It is most commonly a democratic process. Some people called this meetup is as “Kickoff Meeting” The purpose of this first stage is : Every stakeholder has their perspective, so we get to have so much information and solution to the problem. This first stage is very important for fixing the basic work for the rest entire life cycle of Agile and make certain that all the team members are put in a order and get ready for the latest project.

Planning

The second stage is planning, Now from the first stage we have the solution in our hand of the problems that we are facing. In this stage, we have to plan what work to prioritize. The main intention of this stages is to explain the goals, find out the importance and getting ready to the entire team for an productive implementation. This stage is also very important for handling resources, organizing the teams efforts, reducing the risks and eventually contributing to the success of AgileOps life cycle.

Designing

In third stage creates little more reflexive sense in the context of technical project. After completing this designing stage, we come in a phase of performance. This third phase is also important where all the specific plans and structures are manufacture to address the goals and requirements find out in the earlier stages. The main goal of the designing stages is to translate the find out requirement and objectives into detailed plans and blueprints. This stages is basically for creating a robust and successful blueprint that lead the growth and performance of the solution.

Practice

After completing these three stage it’s time to practice what you have learn. This stages is all about complete the techniques and practices that have been created in the stating stages such as Plan, Develop and Test. In the other ways you can say its is an dynamic phase that consists of feedback collection, continuous monitoring to assure that the carry out practices deliver the wanted profit and hand out to the overall goals of AgileOps.

Testing

When you have completed the phase of practice, it’s time to do testing, that means whatever we are thinking of it should be work like that. In the other world we can say, the real word should like same as in real world. The fifth and important stage of AgileOps is testing and it make sure that the quality, reliability and performance of the product s being expand and sustain. AgileOps assure that the system is secure, robust and perform well under several conditions.

Evaluate.

This is the last stage of AgileOps cycle that concentrate on evaluating the outcomes of previous activities to assure that the ongoing improvement and layout with the customers requires the business target. This stage is also important for sustaining the agility and effectiveness of the AgileOps cycle.

Difference Between AgileOps & DevOps.

S.No.	AgileOps	DevOps
01.	John Kern & Martin Fowler invented it in 2001.	John Allspaw and Paul Hammond at Flickr, and the Phoenix Project by Gene Kim invented DevOps in year 2007.
02.	A methodology for creating software	DevOps is not related for creating any software
03.	Some tools used for AgileOps: JIRA, Kanboard etc.	Some tools used for DevOps : AWS, Chef, Puppet etc.
04.	Agile is not related to automation.	DevOps relates to automation.
05.	A large number of team is not essential.	It requires a different team members.

Similarities Between DevOps & AgileOps

Agile and DevOps both have some similar factors which as discussed below:

Both give to benefit the productivity of an Organizations : Agile and DevOps both emphasize company productivity. Agile pushes DevOps for the fastest work and DevOps Pushes Agile to be intensive.

Accepting the narrow Philosophies: In a comprehensive amount, both DevOps and Agile executed the narrow Philosophies.

Collaboration Procedure: Both Agile and DevOps are delivered end to end and bring in collaboration with each other to make the process of tools and data easy and effective.

Conclusion:

Agile plays a central role that helps the developer and operations and also helps to work with the whole organization, data analysts, and business leaders. Agile is a method of software development that collect all the provisions and after that build, test, and release the overall solution. There are six stages of AgileOps Cycle (Meeting, Planning, Designing, Practice, Testing and last one is Evaluate).

A Complete Guide on Technical Debt

Shiwani Sharma — Fri, 22 Sep 2023 17:20:47 +0000

What is Technical Debt?

If you’ve been in the software industry for any period of time, chances are you’ve definitely heard the term “Technical debt”

In software development, the concept of Technical debt plays an important role. Here, the team makes trade-offs during the development process to handle any type of issues and difficulties that may arise in the future. Technical debt is also known as code debt, tech debt, or in some cases, design debt in software companies. It comes into play when there is unfinished work or when a project faces significant complications, and technical debt helps in completing such projects. You can recognize technical debt in the domain of software development when developers are juggling multiple tasks to create a system and write code.

Technical Debt(TD aka Code debt), is a broad concept that includes many of the decisions made and shortcuts taken during the software development cycle.Negative outcomes caused by technical debt typically take the form of badly designed code, deterioration of productivity, additional unplanned costs, delivery delays, and degradation in the quality of the product.

As per definition on Wikipedia:

In software development, or any other IT field (e.g., Infrastructure, Networking, etc.) Technical debt (also known as design debt or code debt) is the implied cost of future reworking required when choosing an easy but limited solution instead of a better approach that could take more time

Usually, technical debt arises when developers are making various compromises to meet targets or deadlines. It becomes more pronounced as software becomes more complex.

What Causes Technical Debt?

Technical debt can arise in Software development, and it’s a common problem that software engineers face in today’s world. There are several contributing factors, including:

Lack of Testing: technical debt occurs when testing is inadequate and insufficient. Incomplete coding can introduce vulnerabilities and hidden bugs, resulting in higher costs. Releasing code without proper testing can lead to technical debt. Organizations must establish plans and techniques to address technical debt caused by insufficient testing.
Avoiding Documentation:lack of documentation makes it difficult for developers to understand how the code works, leading to reduced clarity when addressing future maintenance challenges. Having all the documentation in front of developer is very important and that requires less errors otherwise it causes technical debt.
Lack of Technical Knowledge Technical debt is a major issue stemming from a lack of technical knowledge among various members of an organization, including employees and managers. Investing in staff training to improve technical knowledge can help reduce mistakes. Providing the training to the staff is very important to the employees to get a proper knowledge about technical stuff that helps to convey less mistakes.
Limited Timeframes: software development often encounters technical debt due to tight deadlines. Companies may push developers to make trade-offs for faster delivery, but this can lead to increased costs when addressing technical debt later. Developer have the limited timeframes to complete the tasks with all efficiency and dedication.
Problems Arising with Product-Market Fit: it is essential to understand the concept of product-market fit, which occurs when a product is successfully used by and satisfies users in the market. Organizations must pay careful attention to how their product fits in the market. If a product has unresolved issues or messy code, it may struggle to fit in the market, resulting in the accumulation of technical debt.

Types of Technical Debt

There are three types of Technical debt: Planned, Unintentional, and Unavoidable.

Planned Technical Debt

A strategic decision that is prepared by a team that is software development organization to organized the fastest delivery of a product over addressing the technical problem. It consist the agreement in the development process with the intention of revisiting and convey it later. One of the best example of Planned technical debt is a organization of CRM development that company has to launch a product in the market in a short period of time. The plan consist a timeline for communicate the technical debt. The team execute to refactoring, revisiting the code or building very important improvement while they have extra time and resources.

Unintentional Technical Debt

Unintentional technical debt is also known as technical debt. It occurs rarely when the developer’s not able to understand the requirements or to build it just to fulfill the market need. If the management is not done properly then it causes debt. Unintentional Technical Debt assemble slowly and goes unnoticed until it starts causing the problem. It also consist the introduction of unnecessary problem in the codebase, that is difficult to handle or that reached the pipelines.

Unavoidable Technical Debt

In the technical debt, there are many problems that arises due to circumstances that are beyond the control of the development team or are inherent to the software development process. Unavoidable technical debt happens from the dependencies on third party libraries, services that have the limitations, bugs, or security vulnerabilities.

Managing Technical Debt in Software Development

IMAGE CREDIT:https://www.qentelli.com/thought-leadership/insights/technical-debt-ways-prevent-and-manage-it

There are several ways to manage technical debt in software development:

Documentation & Identification: document the technical debt, including the reasons for its occurrence and its impact on the project. Regularly review code to identify areas with code smells, complexity, or other signs of technical debt.
Planning & Scheduling: create a technical debt backlog with priorities, descriptions, and effort estimates for resolution. Allocate time and resources in each development sprint to address technical debt alongside new features and bug fixes.
Monitoring and Tracking: establish a dashboard or reporting system to provide visibility into the status of technical debt remediation efforts.
Embracing Good Engineering Practices: we all know that prevention is better than cure, and same applies to technical debt as well.Another way to manage the accumulation of technical debt over time is to follow and implement best SDLC practices throughout he SLDC cycle. This includes following the coding standards, software principles for designing, testing best practises, and good documentation. In addition to this, Devops principles and toools like CI/CD, deployment, code reviews, refactoring, and automated testing can help in early detection and rectification of technical debt.
Start doing Hot fixes: any code change or update in the system which causes an issue with Severity level 5 can be immediately fixed with what we call as Hotfix. It’s basically a temporary patch, which is mostly already technical debt by itself. The Hotfix is mostly temporary and immediate solution that gives the team some breathing space to investigate the long-term permanent solution for the issue without disrupting the experience for the user any longer.

Final Conclusion

Technical debt often arises from inadequate and insufficient planning and testing. This article has provided insights into technical debt, its causes, types, and management strategies. When using it within your organization, keep these considerations in mind to minimize costs and ensure smoother software development processes.

However Technical Debt is not always bad, especially if it boosts the chances of a faster and more successful outcome. It’s considered okay if you have the resources to pay it back and give you the competitive edge. Also keep in mind that managing technical debt is a daunting task requiring a nuanced understanding of technology and business goals, effective communication with stakeholders, and a continual learning and improvement culture. By following the ways and best practices shared in this post, technical leaders can successfully navigate stakeholder conflicts, manage technical debt, and foster a culture of technical excellence.

Three things about DevOps in 2020

Mon, 05 Oct 2020 17:20:20 +0000

Knowing the Three C’s (3C’s) of DevOps

Culture, Collaboration, and Continous Change (Integration & Deployment) are the three fundamental principles of the ever-growing popular approach to software delivery, currently referred to as “DevOps.” Coined in 2009 by Patrick Debois, the term (Development and Operations) can be viewed as an extension of Agile and Lean development environments that aims to enhance the software delivery process as an entity. Definitely, there are many controversies over the correct definition of DevOps.

1. DevOps is the next generation of Agile
Perspectives differ on where Agile fits into DevOps (or how DevOps fits into Agile). Some see it as DevOps vs. Agile, while others see them as two sides of an equivalent methodological coin. Others would say that Agile enables DevOps to exist. Since 2009, more IT professionals began to move away from the traditional waterfall approach and adopt a non-linear agile methodology by making each stage of development independent and incorporating continuous testing from the start and throughout the event cycle.

Consequently, this approach improved efficiency and reduced risk by allowing developers to make immediate changes before getting to production, and supported the continuous feedback they received. While Agile methods had always improved development, there was still some discrepancy when it came to Agile implementation, which still embraced the waterfall methodology.

While development wants to be Agile to scale back risk and increase efficiency, the implementation stuck to the linear waterfall structure, slowing the delivery and leaving testing for the top of the method, a process that wrongly divided ownership. This created big bottlenecks in delivery cycles because developers would need to start over if a drag was discovered near the top of the deployment.

2. DevOps needs a Cultural Shift
DevOps is not only about fancy tools or automation methods , it’s more of a Cultural Shift. Changes of any type are often feared in most organisations, hence adopting new methodologies is often a challenging and complex task. Therefore, it’s vital to first define the business need that initiated the discussion about the potential change, and also the challenges that accompany it.

The cultural shift is key element in determining the success of DevOps implementation within an organization.

Today, companies are expected to quickly deliver flawless applications that specialise in best user experience, but without the proper toolchain, team collboration, and behaviour, this seemingly “Walk in the park” process can become a big mess. Ultimately, a defective or broken software delivery means lost business opportunities.

The DevOps culture can only shape-up in environments where everyone agrees with the philosophy. You would like to have a proper blend of correct technology, situational assessment, and attitude for successful software development and delivery.

If everyone within the organization is on the same page and understands the need of clear and consistent communication, developing collaborative work environment, taking ownership and accountability of your work and being transparent with other teams, then the sky is the limit for their success.

3. DevOps needs Unified, Multi-skilled teams (No more Silos)
The evolution of development methodology over the last decade has seen the emergence of new roles, from the Systems-Admins to the SRE, then from the SRE to a full fledged DevOps engineer. Therefore, this career path is common to ascertain on the resumes of the many people within the world of developers and engineers, because the required methodologies and expectations that are expected of latest employees evolve.

As mentioned above, collaboration, communication, and integration are the key elements for incorporating DevOps into any development and delivery environment. Building multipurpose teams that are made from individual talents (for example, developers, sysadmins, and testers) are often of great benefit, but without the proper teamwork and attitude, talent is practically useless. When people know they will trust everyone else, the group as an entity also moves more quickly and efficiently, ultimately resulting in happier customers.

The first step during a DevOps approach involves recognizing how software development, IT operations, and internal control are mutually hooked in to one another. As mentioned above, DevOps relies on cross-department collaboration and open communication between key players within the software delivery process to drive operational efficiency, predictability, and maintainability. Integrating and automating these elements early within the process enables teams to expire software delivery.

While implementing Devops, the quality and delivery of the solution is the single key priority and becomes common goals of all the stakeholders involved, hence the boundaries of roles and responsibilities of different teams become indistinct.

DevOps is the way forward for Enterprise Software
Modern business applications are built with complexities that still continues to grow, thanks to the use of various technologies, multiple end-user devices, and especially process like DevOps that help simplify the complex development and operations ways of doing work and help in delivering a great quality software product at a faster pace.

Going forward Devops is the new way that modern businesses need to adopt for a faster, smarter and high-quality delivery of products.

DevOps vs Agile – understanding the difference

Wed, 30 Sep 2020 15:21:48 +0000

DevOps, is a latest buzzword that has been trending in the software industry for some years now. But in-spite of it’s popularity, there is still a lot of confusion about to how different Devops is from Agile. However the DevOps vs Agile, is a never ending debate in the IT industry.

While both the methodologies have a lot in common , there are some notable Agile and DevOps differences. In this post we are trying to outline, how Agile and DevOps operate independently and the key differences between them.

What is Agile?
Agile is a software development methodology that focuses on an iterative and incremental approach to software development or project management. It was introduced as an alternative to the traditional old waterfall methodology. Agile process breaks the product into smaller pieces and integrates them for final testing.

There are four core values that form the base for Agile development process:

Individuals and interactions over processes and tools.
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

What is DevOps?
DevOps can be defined as a software development culture where the Development and the Operations team work together to improve collaboration and productivity. It can be called as joint (collaborative) responsibility between development, testing, automation and operations team to make the software development and deployment process more faster and smooth.

Unlike traditional software development, DevOps focus on a continuous cycle of building, testing, deploying, and monitoring software. DevOps’ main objective is to deliver quality software efficiently.

A typical Devops lifecycle involves the following processes:

Continuous development
Continuous testing
Continuous deployment
Continuous monitoring
Continuous feedback

Differences between DevOps and Agile

Parameter	DevOps	Agile
Definition	Devops involves collaboration between the Development and Operation teams.	Agile methodology talks about iterative development and focus on collaboration, customer feedback, small, and rapid releases
Purpose	Devops manages end to end SDLC process from development to deployment to operations & monitoring.	Agile is used to manage complex projects mostly limited to development, testing and deployment process.
Teams Involved	Devops involves bigger and larger teams and responsible for collaboration between them.	Agile works best in smaller team size.The smaller the team ,lesser would be members and hence faster would be development, testing and deployment.
Implementation	Devops normally does not follow any standard frameworks.	Agile supports multiple frameworks and can be implemented using Scrum, Kanban, Lean, TDD etc
Target areas	Devops is involved in complete end to end development process(Development ,testing, CI/CD, deployment, monitoring and operations) ensuring faster delivery.	Mostly during the software development process.
Feedback Mechanism	Feedback mostly comes from within the teams internally.	Agile ensures direct feedback from the customer.
Duration	Devops aims to achieve smooth development and deployment process within defined deadlines. The code is ideally deployed daily or every few hours	gile is carried out in units called ’Sprints’. A Sprint duration is normally less than a month, ideally 2 weeks.
Shift left principle	Devops supports both Left as well as Right shift.	Agile only works on Shift-Left principle.
Automation	Automation is an important part of Devops process.	Agile’s main focus is on speed and agility and does not emphasize on automation.
Popular Tools	Devops involves a wide variety of tools , most popular ones being: Git, Jenkins,Puppet, Ansible,Terraform, Nagios,Zabbbix, ELK etc	Commonly used Agile tools are: JIRA,Versionone,LeanKit,Bugzilla, Codegiant etc

Final Conclusion:
Both Agile and Devops aim at delivering quality software within a defined timeline. Where Agile focuses on optimizing the development life-cycle, Devops provide a collaborative environment for the development and operations team to work together and ensure faster software delivery using processes like CI/CD, continuous testing and monitoring.

But the key takeaway here is that both DevOps and Agile are not mutually exclusive and they can coexist within an organization. So any organization transitioning to a DevOps way should not completely abandon existing Agile workflows. DevOps can be considered as an extension of Agile built around the practices that are not in Agile’s focus.
