12. The Cloud Ecosystem
The 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.
