Blue-Green Deployment is running two identical production environments where one serves live traffic while the other gets updates. When the new version is ready, you flip traffic instantly—zero downtime.
Running two identical production environments where one serves live traffic while the other gets updates. When the new version is ready, you flip traffic instantly—zero downtime.
Your app runs on "blue" servers. You deploy updates to "green" servers, test them, then switch all users to green in seconds.
Short for Continuous Integration/Continuous Deployment. It automates testing and deploying your code so you can ship faster with fewer bugs.
The practice of automatically building and testing code every time someone pushes changes. Catches problems early instead of at release time.
Automatically deploying code to production after it passes all tests. No manual "deploy" button—if tests pass, it ships.
A culture and set of practices that bridges development and operations. The goal is faster, more reliable releases through automation and collaboration.
Managing servers, databases, and networks through config files instead of clicking around dashboards. Version controlled, repeatable, and way less error-prone.
