Hello everyone,

I am a Dutch student at the Amsterdam University of Applied Sciences (AUAS) and have recently finished my thesis. My thesis was written on improvements that were made to OpenStack Watcher between February and Juli of 2019. Specifically, many of these improvements were written to aid CERN in deploying Watcher. In addition, the thesis describes methods of collaboration and engaging in communities as well as evaluating strengths and weaknesses of communties.

Since the thesis primarily resolves around OpenStack I would like to share it with the community as well. Please find the thesis attached to this email.

Any feedback, remarks, future advice or other responses are appreciated.

Kind regards, Corne Lukken (Dantali0n)

Thanks for sharing these results Corne, looks great. I've added the [nova] tag to the subject line to sub-thread this just for awareness to nova developers. Section 8 should be interesting for nova developers to see how simple client-side optimizations can be done to improve performance when working with the compute API. The particularly interesting one to me is the regression fix to not use limit=-1 in novaclient when listing servers but specify a hard limit to avoid extra API calls to list servers. Personally I enjoyed this little short-term side project working with the Watcher team on improving the performance of Watcher's nova data model builder code. Thanks to the Watcher team for welcoming my contributions. -- Thanks, Matt
