OpenStack API Benchmarking and Scaling — 3 Test Cases

31

Have you ever been curious how much of a workload the OpenStack control plane can handle before needing to scale horizontally? Based on the load, how will the API performance adjust? How much overhead will load on the OpenStack APIs add to my application deployment timeline? What behavior should I look for to determine its time to add more control plane resources?

These are just a few questions I have been asked about operating OpenStack clouds.  While performing API benchmarking can be measured in many different ways, it is a good idea to have some high level frame of reference.

There are about a million ways to measure performance, and your approach may differ from what I have done.
