Plan a service around real workload and required behavior.

Plan a service around real workload and required behavior.

00:00:06.500 — The idea

Check capacity, waiting time and feature support together. A familiar API format does not prove the underlying service supports every required feature. A local system can serve real work when the necessary controls are in place.

00:00:24.708 — One useful term

Concurrency. The amount of work in progress at the same time.

The amount of work in progress at the same time.

00:00:31.958 — A worked example

At a stable two requests per second and three seconds average time in the system, average work in progress is six. A limit of four bounds admitted work but does not itself prove the timing target.

00:00:47.125 — Your turn to think

Does limiting the queue automatically establish acceptable response time? Pause and decide before continuing.

Pause the video if you need more time.

00:01:05.042 — Why this answer works

No. Test the workload and required features. Distinguish a running process from a service ready to perform its task.

00:01:16.208 — Check 1

Check units and workload assumptions.

00:01:21.500 — Check 2

Check whether the task works, not only whether the process is running.

00:01:28.667 — Check 3

Verify the underlying service supports each required feature.

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