Open Stack

One thing we do at Overstock.com<http://Overstock.com> to try and help with this concern in our dev and test environments is to require that an expiration date is associated with each Openstack resource.  As users spin up an environment, they have an expiration date such that if they don’t renew their ‘lease’, their instances are suspended and then destroyed shortly thereafter.  This expiration information is stored outside Openstack in the system that they interact with for requesting resources.

Doesn’t solve all your problems - since users can (and often do) just renew their environments all the time, but it does ensure that if people do not tell us that they are still actively using their resources, that they are removed.

Dear Openstack community,

We are a medical research institute and we have been running HPC for many years, we started playing with Openstack a few months ago and we like it’s flexibility to deploy multiple environments. However we are quite concern about the resource utilization, what I mean is that, in HPC the resources are released for the rest of the community once job has finished, however a VM keeps the resources for the owner of the vm until the instance is killed.

I would like to ask, how do you organize your resources used by Openstack to maximize utilization across the organization?

Thank you very much
