What is Blue-Green Deployment?
A deployment strategy that runs two identical production environments, switching traffic from the old to the new.
Why It Matters
Blue-green deployments enable zero-downtime releases and instant rollback if something goes wrong.
Real-World Example
Deploying the new version to the green environment, testing it, then switching all traffic from blue to green.
“Understanding terms like Blue-Green Deployment matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
