Question

Which specific architectural approach for model deployment allows for near-zero downtime by running two identical production environments where traffic is switched from the old version to the new one only after the new one is verified?

Accepted Answer

The architectural approach described is called Blue-Green deployment. In this strategy, you maintain two identical production environments, known as Blue and Green. One environment, such as Blue, is currently live and serving all production traffic. The other environment, Green, is kept idle or used for testing the new version of the software. Once the new version is deployed to the Green environment and passes all verification tests, you switch the traffic router to point to the Green environment. This makes Green the new live production environment, while Blue becomes the idle environment. This method ensures near-zero downtime because the switch occurs almost instantaneously at the router level. If any issues are discovered after the switch, you can immediately revert the traffic back to the original Blue environment, providing a reliable and fast rollback mechanism.
