What is DevOps?
DevOps is a collaboration between development and operation teams, which enables continuous delivery of applications and services to our end users.

Benefits of DevOps
Continuous delivery of software
Better collaboration between teams
Easy deployment
Better efficiency and scalability
Errors are fixed at the initial stage
More security
Less manual intervention (which means fewer chances of error)
DevOps Lifecycle
Now that you know why DevOps and what is it exactly, we will learn all about the DevOps Lifecycle which will give you a clarit on why devops, that is divided into six different phases which will give a clear idea on why Devops:

Source Code Management – In this phase, the business owners and software development team discuss project goals and create a plan. Programmers then design and code the application, using tools like Git to store the application code.
Continuous Build and Test – This phase deals with building tools, like Maven and Gradle, then taking code from different repositories and combining them to build the complete application. The application is then tested using automation testing tools, like Selenium and JUnit, to ensure software quality.
Continuous Integration – When the testing is complete, new features are integrated automatically to the existing codebase.
Continuous Deployment – Here, the application is packaged after being released and deployed from the development server to the production server. Once the software is deployed, operations teams perform tasks, such as configuring servers and provisioning them with the required resources.
Continuous Monitoring – Monitoring allows IT organizations to identify issues of specific releases and understand the impact on end-users.
Software Released – After all the phases are completed and the software meets the user’s requirement, it is released into the market.

According to IDC, 40% of DevOps teams will invest in tooling and focus on business KPIs by 2023. The number of organizations releasing codes for specific applications will increase to 30% by 2023 from the current 3% (as of 2019).
