CICD

✅ Problem Statement: Why Do We Need CI/CD?

• Traditional software development processes often involve:

  • Manual testing and deployment of code, which can be time-consuming and error-prone.

  • Inconsistent environments between development, testing, and production leading to “it works on my machine” issues.

  • Slow, manual release cycles that impact delivery speed and time to market.

  • Difficulty in ensuring high-quality code and reducing integration problems during releases.

  • Increased risks of downtime and bugs in production due to lack of automation and quality control.

🛠️ Solution: What CI/CD Offers

• CI/CD is an automation pipeline that streamlines the process of building, testing, and deploying code.

• Key benefits:

  • Continuous Integration (CI):

    • Automates code integration, allowing teams to merge small changes frequently.

    • Ensures code quality through automated tests (unit, integration, etc.) that run on every commit.

  • Continuous Deployment (CD):

    • Automates the deployment process, pushing code to production with minimal manual intervention.

    • Reduces deployment risk and ensures faster, reliable delivery of new features and fixes.

  • Automated testing: Prevents bugs from reaching production by catching issues early in the pipeline.

  • Faster feedback: Developers receive immediate feedback on code quality, making it easier to fix issues early.

  • Supports rollbacks and canary releases for safe updates.

  • Tools like Jenkins, GitHub Actions, GitLab CI, CircleCI, and ArgoCD help automate the entire pipeline.
