Yes, this is the continuation of T206636 <https://phabricator.wikimedia.org/T206636>. In T221631#5131322 <https://phabricator.wikimedia.org/T221631#5131322>, @bd808 wrote: > 1.

Spec and rack specific hardware sized for these instances using the "fake ironic" model of making them virt servers with a single instance each In term of constraints: - We know that IO is critical to the performance of WDQS in its current implementation, and we suspect the same thing about any replacement solution. So I'm not sure that sharing the same IO on the 3 VMs is a great solution. - We need to test the distributed nature of whatever replacement solution. By hosting the 3 VMs on the same physical host, we will probably hide whatever issue might come from increased latency between different physical servers. So my preference would be to have dedicated servers, with a single VM on each, basically using our cloud infrastructure only as an isolation layer. I'm not sure how much sense this makes and we're very much open to suggestions!
