What is DevOps: DevOps Methodology, Principles & Stages Explained

DevOps is the combination of practices, tools, and cultural philosophy through which development and IT teams’ processes can be automated and integrated. It puts a lot of focus on team collaboration, cross-team communication, and technology automation. 

The DevOps movement began around 2007 when the software development and IT operations groups highlighted concerns about the traditional software development approach, where developers who created code worked away from operations who distributed and supported the code. 

The phrase DevOps, a mix of development and operations, reflects the idea of combining different disciplines into one continuous process.

DevOps Methodologies

Automation and agility are the exclusive focuses of DevOps methodology, and its sole objective is to hasten the development of apps. Furthermore, continuity and consistency are key components of the DevOps lifecycle.

With continuous integration, development, feedback, monitoring, testing, delivery, and deployment, it powers the entire production process. Let’s talk about the DevOps lifecycle stages:

Continuous Development

Continuous development may require the use of a CI/CD tool, but the two are not technically equivalent. Continuous Integration/Continuous Delivery, or CI/CD, refers to two distinct approaches that cooperate to support continuous development. Automated software delivery across coding, testing, and delivery is made feasible by the CI/CD pipeline. Continuous testing and deployment are two more techniques that are part of continuous development. 

Continuous Integration

Continuous integration involves developers routinely merging their code changes into a common repository, which is followed by automated builds and tests.

Continuous Testing

Software testing that incorporates testing at each stage of the development life cycle is known as “continuous testing” in DevOps. Continuous testing’s objective is to assess the software’s quality through early and frequent testing as part of a continuous delivery process. 

Continuous monitoring

DevOps staff may monitor and identify compliance problems and security risks using an automated procedure at every stage of the DevOps pipeline. It aids teams or organizations in keeping track of important indicators, spotting problems as they arise, and researching solutions in real time. 

Continuous Delivery

To evaluate application modifications across numerous dimensions before releasing them to users, continuous delivery enables developers to automate testing beyond just unit tests. 

Continuous Deployment

Code updates to an application are automatically pushed into the production environment as part of a software development method called continuous deployment. During this stage, tools like Chef, Ansible, Docker, Puppet, and Vagrant are employed. 

DevOps Principles 

Teams should adhere to fundamental DevOps principles to maximize the benefits of the discipline:

Collaboration

Throughout the development and deployment cycle, the development and operations teams come together to form a functional team that communicates, exchanges feedback, and work together.

Automation

An essential component of a CI/CD pipeline, automation lowers human error rates and boosts team output.

Customer-focused action

By utilizing real-time live monitoring and quick deployment, DevOps processes enable rapid collection and response to customer feedback.

End-to-end operations

Teams shouldn’t “build in a bubble” or make assumptions about how users would use the software when developing software. DevOps teams should have a stronghold of the product, from conception to use.
