DevOps is a set of practices that automates the processes between software development and IT teams, in order that they can build, test, and release software faster and more reliably.

DevOps is the collaboration between development and operations that emphasises better collaboration and tighter integration. It unites agile, continuous delivery and automation to help development and operations teams be more efficient, innovate faster, and deliver higher value to businesses and customers.

Why DevOps?

CI/CD: DevOps allows Agile Development Teams to implement Continuous Integration and Continuous Delivery. This helps them to launch products faster into the market.

Predictability: DevOps offers significantly lower failure rate of new releases

Reproducibility: Version everything so that earlier version can be restored anytime.

Maintainability: Effortless process of recovery in the event of a new release crashing or disabling the current system.

Time to market: DevOps reduces the time to market up to 50% through streamlined software delivery. This is particularly the case for digital and mobile applications.

Greater Quality: DevOps helps the team to provide improved quality of application development as it incorporates infrastructure issues.

Reduced Risk: DevOps incorporates security aspects in the software delivery lifecycle. It helps in reduction of defects across the lifecycle.

Resiliency: The Operational state of the software system is more stable, secure, and changes are auditable.

Cost Efficiency: DevOps offers cost efficiency in the software development process which is always an aspiration of IT companies' management.

Breaks larger code base into small pieces: DevOps is based on the agile programming method. Therefore, it allows breaking larger code bases into smaller and manageable chunks.

DevOps Lifecycle

DevOps Lifecycle
DevOps Lifecycle

1. Development
Development of software takes place constantly. The entire development process is separated into small development cycles. This benefits DevOps team to speed up software development and delivery process.

2. Testing
QA team use tools like Selenium to identify and fix bugs in the new piece of code.

3. Integration
New functionality is integrated with the prevailing code, and testing takes place. Continuous development is only possible due to continuous integration and testing.

4. Deployment
The deployment process takes place continuously. It is performed in such a manner that any changes made any time in the code, should not affect the functioning of high traffic website.

5. Monitoring
Operation team will take care of the inappropriate system behaviour or bugs which are found in production.

DevOps supports a team to be more customer-centric with robust monitoring and testing procedures and enhancing the level of responsibility and quality of products delivered
