CI/CD Explained

[Lomanu4]

CI/CD stands for continuous integration and continuous delivery/deployment

Aimed to streamline and accelerate the SDLC (Software Development Life Cycle) to ensure faster and more reliable delivery of applications.

Importance of CI/CD


CI/CD helps decreasing complexity, increase efficiency and streamlining workflows. CI/CD enables teams to:

• Release code faster, while ensuring the quality of the applications.
• Automate repetitive tasks, such as testing, building, and deployment.
• Reducing human errors and human intervention. ?
• Decrease Complexity. ?
• Increase customer satisfaction through faster feedback loop and frequent update. ?

CI - continuous integration


CI is a Practice of :

• Integrating all your code changes into main branch early and often
• Running automated builds and tests (e.g., unit tests, linting, static analysis) on every commit or pull request.

Benefits of CI:

• Early detection of bug, security issue, and integration conflicts ?
• Minimizing code integration conflict, by merging frequently ?
• Faster issues identification ?
• Verify code changes

CD - Continuous Delivery/Deployment


CD can mean two things:

• Continuous Delivery
• Continuous Deployment

Continuous Delivery

• Ensure that code is in Deployable state
• Automate Builds and Tests (e.g., unit tests, integration test) ?

Continuous Deployment

• Automates release/deployment of application to production ?
• Reduce manual process by operations ?
• Faster app delivery

Summary


CI/CD pipeline can streamline the creation, testing, and deployment of applications.
Improving quality and speeds up the delivery.

• CI - Continuous Integration
  • Minimizing conflicts ?
  • Detect issues faster ?
• CD - Continuous Delivery/Deployment
  • Ensuring quality ?
  • Automate application's release ?

Benefits:

• Faster release cycles ?️
• Fewer errors and bugs ?
• Shorter feedback loops ?
• Reduced operational workload ?️
• Faster recovery from failures ‍?
• Higher team morale and customer satisfaction ?
