Job-oriented VM state synchronization in CloudStack

Sign up or log in to save this to your schedule and see who's attending!

Several major pain-points of the old model are discussed, these pain-points drive the major motivation for CloudStack to look for a more loose-coupled model for future evolutions. A job-oriented processing model is presented, the new model decouples the in-place monolithic synchronization process into individual job-oriented context-aware synchronization processes, which provides an eventually consistent VM state picture between CloudStack and underlying hypervisors in a loosely-coupled fashion. The necessary underlying supporting facilities on message bus, job scheduling, how to make the switch with minimal impact to large legacy code base and future work for performance optimization are also discussed.
