I think this is really neat. As a 3rd party ci operator managing a small nodepool cloud, leveraging #3 would be really great!

HP is supplying two racks of machines, and we will operate each as an independent cloud. I think this is a really good idea, and will do a lot for OpenStack. Here's what we would get out of it: 1) More test resources. The primary goal of this cloud will be to provide more instances to nodepool. This would extend our pool to include a third provider meaning that we are more resilient to service disruptions, and increase our aggregate capacity meaning we can perform more testing more quickly. It's hard to say for certain until we have something spun up that we can benchmark, but we are hoping for somewhere between an additional 50% to 100% of our current capacity. 2) Closing the loop between OpenStack developers and ops. This cloud will be deployed as often as we are able (perhaps daily, perhaps less often, depending on technology) meaning that if it is not behaving in a way developers like, they can fix it fairly quickly. 3) A fully open deployment. The infra team already runs a large logstash and elasticsearch system for finding issues in devstack runs. We will deploy the same technology (and perhaps more) to make sure that anyone who wants to inspect the operational logs from the running production cloud is able to do so. We can even run the same elastic-recheck queries to see if known bugs are visible in production. The cloud will be deployed using the same tools and processes as the rest of the project infrastructure, meaning anyone can edit the modules that deploy the cloud to make changes. How is this different from the TripleO cloud? The primary goal of the TripleO cloud is to provide test infrastructure so that the TripleO project can run tests that require real hardware and complex environments. The primary purpose of the infra cloud will be to run a production service that will stand alongside other cloud providers to supply virtual machines to nodepool. What about the infra team's aversion to real hardware? It's true that all of our current resources are virtual, and this would be adding the first real, bare-metal, machines to the infra project. However, there are a number of reasons I feel we're ready to take that step now: * This cloud will stand alongside two others to provide resources to nodepool. If it completely fails, infra will continue to operate; so we don't need to be overly concerned with uptime and being on-call, etc. * The deployment and operation of the cloud will use the same technology and processes as the infra project currently uses, so there should be minimal barriers for existing team members. * A bunch of new people will be joining the team to help with this. We expect them to become fully integrated with the rest of infra, so that they are able to help out in other areas and the whole team expands its collective capacity and expertise. If this works well, it may become a template for incorporating other hardware contributions into the system. Next steps: We've started the process of identifying the steps to make this happen, as well as answering some deployment questions (specifics about technology, topology, etc). There is a StoryBoard story for the effort: https://storyboard.openstack.org/#!/story/2000175 And some notes that we took at a recent meeting to bootstrap the effort: https://etherpad.openstack.org/p/InfraCloudBootcamp I think one of the next steps is to actually write all that up and push it up as a change to the system-config documentation. Once we're certain we agree on all of that, it should be safe to divide up many of the remaining tasks. -Jim __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
