How are DevOps and Agile different?

DevOps 4 min read

Both Agile and DevOps are software development methodologies, i.e. they constitute steps, guidelines, mechanisms, processes, pre-established templates of how a software development process should be strategised, as well as the professionals involved in each of the stages.

Although they usually have many aspects in common, there are several differences that are important to identify – in this article we will help you discover them all.

Agile Methodology

It is a development methodology that has gained a lot of popularity in recent years, displacing the traditional ones. This methodology focuses on iterative development with an incremental and evolutionary approach.

This means that the development of the final product is divided or fragmented into smaller tasks. These tasks are developed and tested until there are no errors. Therefore, upon completion, they are integrated to perform the final tests. When implementing this methodology there are different frameworks that make modifications and adjust it to their environment and needs.

DevOps

This software development methodology deploys its full potential around integration, communication and collaboration between different computer technology professionals to facilitate rapid development. Development and operations departments come together to create a production structure that generates more effective codes. This link is the great pending subject of other development methodologies. It is an alliance that elevates the concept of agility to a higher level like never seen before.

Let’s now analyse some key differences between Agile and DevOps

Team size

Perhaps the main difference that exists between these two methodologies is the number of people involved in development. The first is designed for a small team, while the second usually involves a greater number of professionals. It is said that everyone who can be considered as a stack holder must be part of the team.

Work Fractionation

On the other hand, the agile methodology divides its achievements into sprints, each of the sprints usually lasts a little less than a month. While DevOps tries to deliver code every day or even every few hours. This is possible because the feedback occurs only within the development team itself, unlike the first. Agile employs sprints, which range from a week to months as a way to manage the development program, while DevOps focuses on quick launches that begin with several times per day.

Documentation

The agile approach gives greater importance to development in a work system that caters documentation to a second level of importance. This works because team members are able to do any job.

However, in the DevOps methodology it is necessary to generate more detailed documentation because the program is in constant transit between the development team and the operations team.

Scope

Not a few specialists place the scope as one of the elements that most accentuates the difference between the two methodologies.

The first focused since its inception on accelerating the development process; however, it neglected the evidence. While the second, taking advantage of the good and proven practices of the first, introduced a marked holistic character. This means that during any stage of the code, the team must see it comprehensively and ensure that it works as designed.

Clearly these are two methodologies that cannot be considered incompatible, but it is not fair to say that one is the evolution of the other. They simply raise two approaches with marked differences in the conception of the productive process.

Other Differences

Both DevOps and Agile can work together as they can complement each other. DevOps promotes a fully automated continuous deployment and integration process to allow frequent launches, while Agile offers the ability to quickly adapt to changing requirements and better collaboration between different smaller teams.

When applied in tandem, Agile and DevOps can allow organisations to develop and implement technology with significantly faster speed. There is an emphasis on putting customer needs at the forefront of any technology that is being developed.

That said, the potential inconveniences faced by both DevOps and Agile are rooted in the “significant cultural change” that both require. DevOps requires two isolated teams to foster a relationship to work together, and Agile requires organisations to move away from a conventional static work environment.

Individually, Agile has many advantages over the conventional cascade model, but it presents certain challenges, especially for larger equipment. Agile has several advantages that include user-centred development, greater team collaboration, fast product delivery and flexibility. However, it comes with some challenges, such as the uncertainty of the final goal, and making it work well for large teams.

As for DevOps, this can accelerate product innovation, but if it is not executed correctly it can cause a load. It allows better quality, performance and accelerated product innovation. However, if it is not done correctly, DevOps can become an additional burden for the equipment and a large amount of investments in wasted tools and infrastructure.
The difference between DevOps and Agile is further highlighted in the following table:

Emphasise the barriers between developers and management.DevOps is about software deployment and operations teams.
Focus on functional and non-functional readiness.Address the gap between development and operations teams.
Address the gap between customer needs and the development team.It focuses on operations and business preparation.
Agile development mainly involves the way companies think about development.DevOps emphasizes deploying software in the most reliable and secure way, and these are not always the fastest.
Agile development places great emphasis on training all team members to have a variety of similar and equal skills. Therefore, when a problem arises, any team member can get help from any member without team leadership.DevOps is similarly divided and conquered, spreading skills between development and operations teams. It also maintains consistent communication.
Agile development management “sprint”. This means that the timeline is much shorter (less than a month) and multiple features are generated and published during this time.DevOps strives to consolidate deadlines and benchmarks for major releases, rather than smaller and more frequent versions.

With these ideas in mind, it is clear to see that both Agile and DevOps seek to contribute the value of the end user in a more efficient way, but from different angles. Agile focuses on making developers and development cycles more efficient, while DevOps launches the operations team to enable continuous integration and continuous delivery.

Conclusion

DevOps has become one of the most popular buzzwords in the computer industry. DevOps is rather a more advanced version of Agile, at the project execution level. Agile’s focus is on making the software development process more efficient, while DevOps focuses on reducing the gap between development and operations; It is therefore the complete execution of the project.
