DevOps vs Agile – understanding the difference

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:

  1. Continuous development
  2. Continuous testing
  3. Continuous deployment
  4. Continuous monitoring
  5. Continuous feedback

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.
