CI/CD Pipeline

Overview of CI/CD ⇒

What is CI/CD?

CI/CD stands for Continuous Integration (CI) and Continuous Deployment (CD). It is a methodology used in modern software development to automate and streamline the entire process of building, testing, and deploying applications.

It is a crucial part of the Software Development Life Cycle (SDLC) and follows an automated approach to ensure that changes in the codebase are tested and deployed efficiently without manual intervention.

Key Concept:

➡ CI = Continuous Build + Continuous Testing

FCFS Principle in CI/CD

The First-Come, First-Served (FCFS) principle is often applied in CI/CD pipelines.

It ensures that changes are processed in the order they are received, preventing delays and conflicts.
Similar to how a queue works, the first commit that enters the pipeline will be the first one to be built, tested, and deployed.

CI/CD Pipeline: Breaking It Down ⇒

A CI/CD pipeline is a structured workflow that automates software development, testing, and deployment. It consists of multiple stages that ensure code changes are safely and efficiently integrated into production.

1️⃣ Key Components of a CI/CD Pipeline

Component	Description
Continuous Integration (CI)	The process of frequently integrating code into a shared repository, followed by automated builds and tests.
Continuous Delivery (CD)	Ensures that every change is ready for deployment after passing tests.
Continuous Deployment (CD)	Extends Continuous Delivery by automating the release process so that changes reach production without manual approval.
Automation	CI/CD pipelines automate repetitive development tasks like code testing and deployment.
Testing	Automated tests run at every stage to catch bugs early.
Deployment	Code is deployed to production seamlessly, ensuring a smooth release cycle.
