Open Stack

+1 for Boris’ suggestion. Many of us use Rally to probe our clouds and have significant tooling behind it to integrate with local availability reporting and trouble ticketing systems. It would be much easier to deploy new functionality such as you propose if it was integrated into an existing project framework (such as Rally).

Sam,

Seems like a good plan and huge topic ;)

I would as well suggest to take a look at the similar efforts in OpenStack:
- Failure injection: https://github.com/openstack/os-faults
- Rally Hooks Mechanism (to inject in rally scenarios failures): https://rally.readthedocs.io/en/latest/plugins/implementation/hook_and_trigger_plugins.html


Best regards,

Hi All,

This is a follow up for OpenStack Extreme Testing session[1]
we did in MEX-ops-meetup.

Quick intro for those who were not there:
In this work, we proposed to add new testing framework for openstack.
This framework will provides tool for create tests with destructive
scenarios which will check for High Availability, failover and
recovery of OpenStack cloud.
Please refer the link on top of the [1] for further details.

Follow up:
We are planning periodic irc meeting and have an irc
channel for discussion. I will get back to you with those details soon.

At that session, we did not have time to discuss last 3 items,
Reference architectures
 We are discussing about the reference architecture in [2].

What sort of failures do you see today in your environment?
 Currently we are considering, service failures, backend services (mq,
DB, etc.) failures,
 Network sw failures..etc. To begin with the implementation, we are
considering to start with
 service failures. Please let us know what failures are more frequent
in your environment.

Emulation/Simulation mechanisms, etc.
 Rather than doing actual scale, load, or performance tests, we are
thinking to build a emulation/simulation mechanism
to get the predictions or result of how will openstack behave on such
situations.
This interesting idea was proposed by the Gautam and need more
discussion on this.

Please let us know you questions or comments.

Request to Mike Perez:
 We discussed about synergies with openstack assertion tags and other
efforts to do similar testing in openstack.
 Could you please give some info or pointer of previous discussions.
