DevOps Lifecycle

The lifecycle is not linear—it is a continuous loop, where feedback from later stages improves earlier stages.

DevOps Lifecycle Overview

The DevOps lifecycle connects development and operations teams into a single workflow.

🔸 Encourages collaboration between teams
🔸 Automates repetitive tasks
🔸 Improves software quality
🔸 Enables faster and more reliable releases

Each phase plays a critical role in delivering stable and scalable software.

Plan Phase

The Plan phase is where ideas and requirements are defined.

🔸 Understand business requirements
🔸 Define project scope and goals
🔸 Create tasks, timelines, and priorities
🔸 Plan features and improvements

Proper planning helps reduce rework and confusion later in the lifecycle.

Code Phase

In the Code phase, developers start writing application code.

🔸 Developers write and update code
🔸 Source code is managed using version control tools like Git
🔸 Code reviews are performed
🔸 Collaboration happens through repositories

This phase ensures code is well-organized, trackable, and collaborative.

Build Phase

The Build phase converts source code into executable applications.

🔸 Compile source code
🔸 Resolve dependencies
🔸 Package applications
🔸 Generate build artifacts

Build automation tools ensure consistency and reduce manual errors.

Test Phase

The Test phase ensures the software works as expected.

🔸 Run automated tests
🔸 Perform unit and integration testing
🔸 Identify bugs and issues early
🔸 Improve code quality

Automated testing helps catch problems before they reach production.

Release Phase

In the Release phase, tested builds are prepared for deployment.

🔸 Approve builds for release
🔸 Tag versions
🔸 Prepare release notes
🔸 Ensure stability and readiness

This phase ensures only reliable builds move to production.

Deploy Phase

The Deploy phase delivers the application to production or staging environments.

🔸 Deploy applications automatically
🔸 Use CI/CD pipelines
🔸 Minimize downtime
🔸 Ensure consistent deployments

Automation in this phase makes deployments faster and safer.

Operate & Monitor Phase

This phase focuses on maintaining and observing the application after deployment.

🔸 Monitor application performance
🔸 Track system health and logs
🔸 Handle incidents and failures
🔸 Collect feedback for improvement

Monitoring helps teams quickly identify issues and improve future releases.

Why the DevOps Lifecycle Is Important

Understanding the DevOps lifecycle helps you:

🔸 Deliver software faster
🔸 Improve collaboration between teams
🔸 Reduce deployment failures
🔸 Build reliable and scalable systems

It forms the foundation of modern DevOps practices.
