In 2010, about 75 people showed up for the first OpenStack Summit in Austin, Texas.

This week, roughly 6,000 have descended on Vancouver for the 11th installment of the twice-yearly event, according to unofficial estimates. The open source cloud architecture project has gained huge traction with contributors, vendors, and increasingly with users — ecosystem momentum that has given OpenStack a leg up on competing platforms such as CloudStack, which even partisans in Vancouver privately admit has some technical advantages over OpenStack.

Hoping to take advantage of that community base, OpenStack on Tuesday launched a community app catalog, where community members can share developer tools for setting up new applications and services on an OpenStack cloud.

Still in beta, the community-curated marketplace already features applications that enable self-service provisioning of Oracle databases or deployment of container-orchestration system Kubernetes, among other examples.

"This really is just the beginning," OpenStack Foundation COO Mark Collier said as he announced the app catalog's launch during a Tuesday keynote. "Knowing this community, I expect there will be hundreds of additional applications in the next few days."

Also revealed Tuesday were locations for the next two OpenStack Summits. In October, Tokyo will play host city, and in the spring of 2016 the event will return to the place where it all started: Austin, Texas.
