Overview of CI/CD:

Notes on CI/CD Pipeline

Key Concepts:

1. Methodology:
   • CI/CD Pipeline is a methodology used in software development for automated processes.
   • It encompasses Continuous Integration (CI), Continuous Delivery (CD), and Continuous Deployment (CD).
2. SDLC:
   • CI/CD is an integral part of the Software Development Life Cycle (SDLC).
3. Automated Processes:
   • The pipeline involves automating steps to ensure efficiency and reliability in the development process.

Examples:

1. CI/CD Process Flow:
   • The flowchart depicted involves steps such as washing, cutting, and cooking ingredients like Paneer, Onion, and Tomato.
   • This analogy helps in understanding the sequential and automated nature of a CI/CD pipeline.
2. First-Come, First-Served (FCFS):
   • The diagram at the bottom illustrates the FCFS principle, highlighting the orderly processing of tasks or items.

Before Continuous Integration

1. Process Without CI:
   • Developers commit code to a repository (e.g., GitHub).
   • Code is integrated and tested in cycles, typically every 7 days.
   • This process often leads to delayed feedback and potential integration issues.

Examples:

1. Pre-CI Workflow:
   • The diagram illustrates the involvement of developers, the repository, and the integration and testing steps.
   • It shows the time delays (3 days for commit, 7 days for integration and testing).
