Rally can generate load with passed users now!

Finally, I happy to announce that OpenStack Rally team, after more than 1 year of work, finished support of benchmarking with already existing users in OpenStack. This is crucial feature that simplifies adoption of Rally in enterprise world.

Why it’s so important?

There are 2 very important use cases from production world:

  1. It’s simpler to run Rally against production cloud
    Rally can use existing users instead of creating own which is impossible in case of r/o Keystone backends like LDAP and AD.
  2. It’s safer to run Rally against production cloud
    Rally can be run from isolated group of users and if something went wrong it won’t affect rest of the cloud users.

Rally Tricks: “Stop load before your OpenStack goes wrong”

Benchmarking pre-production and production OpenStack clouds is not a trivial task. From the one side it’s important to reach the OpenStack cloud’s limits, from the other side the cloud shouldn’t be damaged. Rally aims to make this task as simple as possible. Since the very beginning Rally was able to generate enough load for any OpenStack cloud. Generating to big load was the major issue for production clouds, because Rally didn’t know how to stop the load until it was to late. Finally I am happy to say that we solved this issue.

With the new feature “stop on SLA failure” things are much better.
