What Is DevOps and How Does It Work?

DevOps has brought a paradigm shift in IT firms across the globe. It is now popularly known as culture in firms rather than technology because it breaks the traditional silos and brings the developers and IT operations team together. Many companies have seen a tremendous rise in results in terms of product development & delivery, better coordination between teams, work culture, and customer experience.

What is DevOps?

DevOps is a set of practices that brings development teams and operation teams together. DevOps brings individuals, processes, and products together to release software of high quality with greater efficiency to provide greater value to customers. It is an evolution from the agile model and uses pre-built software, which is easy to deploy and reliable.

The development team submits the application to the operations team for implementation using this modern code deployment approach and the operations team monitors the application to provide the relevant feedback. This approach helps to speed the development of the application by reducing the risks of continuous production and providing accurate reviews for faster and better launches. Thus, DevOps enables continuous integration (CI) and continuous delivery (CD) of value to end-users.

How does DevOps work?

In DevOps the team works together to achieve the ultimate objective, beginning from design and development to testing automation and from continuous integration to continuous delivery.

Individuals with both development and operational skill sets work together and use different CI/CD and testing tools to rapidly respond to consumer requests and address problems and bugs.

Quality assurance and security teams may also become more closely aligned with development and operations teams throughout the application lifecycle in some DevOps models. This is often referred to as DevSecOps when security is the priority of everyone in a DevOps team.

DevOps works by following each phase of the DevOps life cycle which includes continuous development, continuous integration, continuous testing, and continuous deployment.

Continuous Development - Plan application objectives and code the requirementsContinuous Testing – Verify the product for actual usage in a live environmentContinuous Integration – Plan tests and build the productContinuous Deployment – Ensures product is deployed with maximum accuracyContinuous Monitoring - Monitor the product output and find the problem areasTeams use techniques to automate processes that have been manual and slow traditionally.

They use a stack of technologies and tools that help them rapidly and efficiently develop and deploy programs. These tools often help engineers accomplish tasks independently that would usually require assistance from other teams, and this further increases the pace of a team.

There are various DevOps tools available that help the team to speed up the process, increase collaboration between teams and deliver a high-quality product to customer

Conclusion: DevOps is an evolution from the agile model. It is a culture, movement, or practice where collaboration and communication of both software developers and other IT professionals are emphasized while automating the software delivery process and infrastructure changes.

This helps to create a community and ecosystem where applications can be designed, reviewed, and released easily, regularly, and more consistently.
