How scalable is CloudStack? | Boris Stoyanov

CloudStack has always known to be scalable, but just how scalable? In this talk, Boris discusses the known and anticipated CloudStack scalability limits. He also shares design decisions that should be made to accommodate growth and uses examples of organisations running CloudStack at a massive scale.

The CloudStack Collaboration Conference 2025 took place in November 19-21 in Milan, Italy, bringing together CloudStack users, developers, and operators from 40+ countries. This annual, in-person event provided a unique opportunity for the global CloudStack community to connect, collaborate, and help shape the future of the open-source platform.
