Question
What is the name of the deployment strategy that involves maintaining two separate environments, one live and one for testing updates, to minimize downtime?
A. Canary deployment.
B. Blue-green deployment.
C. Rolling deployment.
D. Incremental deployment.
Answer
B. Blue-green deployment.
Explanation
Blue-green deployments require two separate deployment environments. The blue environment is live and actively handles client requests, while the green environment accepts updates and bug fixes.
When updates are complete, the green environment goes live, although the blue environment is not immediately taken down in case the new deployment fails and the old environment needs to be reactivated.
