00:00:00.000 — What you will learn

Check readiness and recovery before promoting a new version.

00:00:06.375 — The idea

A process being alive does not mean it is ready to serve the task. Check its configuration and required behavior. Keep a tested route back to a compatible previous version.

00:00:20.375 — One useful term

Readiness check. A test that a service can perform its required job, not merely that its process is running.

00:00:30.417 — A worked example

Version two fails readiness after a configuration change. The simulator blocks promotion and restores version one. It records recovery time and checks that no sample secret is embedded.

00:00:45.625 — Your turn to think

Does a running but incompatible process count as ready? Pause and decide before continuing.

Pause the video if you need more time.

00:01:02.458 — Why this answer works

No. Check the actual task and configuration. If recovery fails, inspect compatibility between code, artifacts and data.

00:01:15.208 — Check 1

Separate configuration from code.

00:01:30.250 — Now try a different case

Open the lesson and try its different practice case. Use every check in the full task. Watching alone does not mark the lesson complete.
