CI/CD Explained

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 🔥
