Building my DevOps Portfolio 🚀

Project 6: Continuous Integration on AWS Cloud.

One of the benefits of working at EY is Udemy for Business. I enrolled in the DevOps Projects | 20 Real-Time DevOps Projects course to enhance my DevOps portfolio and I’m sharing this process for educational purposes. Thanks Rox for giving me the free credits to keep using AWS to develop this project! Thanks for your support to the DevOps Community worldwide.

Scenario

• ✅ Agile Software Development Life Cycle.
• ✅ Developers make regular code changes.
• ✅ These commits need to be Build & Tested.
• ✅ Usually Build & Release Team will do this job or developers with responsibility to merge and integrate code

Problem

• ❌In an Agile SDLC, there will be frequent code change.
• ❌Not so frequently code will be tested.
• ❌ Developers need to rework to fix bugs and errors.
• ❌ Manual Build and release process.
• ❌ Inter team dependencies.
• ❌CI server maintenance
• ❌Operational overhead to maintain server like Jenkins, Nexus, Sonar, Git, etc

Solution: Continuous Integration

• ♾️ Build and test for every commit.
• ♾️ Automated process.
• ♾️ Notify for every build status.
• ♾️ Fix code if bugs or error found instantly rather rather than waiting.
• ♾️ Cloud services for CI to remove Operations overhead.

Benefits CI Pipeline

• ✅ Short Mean time to recovery (MTTR).
• ✅ Agile.
• ✅ No human intervention.
• ✅ Fault isolation.
