The Cloud EcosystemThe Haizea project

Act as a drop-in replacement for OpenNebula’s default scheduler.

By working together, OpenNebula could offer resource leases as a fundamental provisioning abstraction, and Haizea could operate with real hardware through OpenNebula.

Integrating OpenNebula and Haizea provides the only VI management solution offering advance reservation of capacity. As Table shows, other VI managers use immediate provisioning or best-effort provisioning. However, private clouds — specifically those with limited resources in which not all requests are satisfiable immediately owing to lack of resources — stand to benefit from more sophisticated VM placement strategies supporting queues, priorities, and ARs.
