ResilientVM: High performance virtual machine recovery in the cloud
Abstract
In this paper, we present a scalable parallel virtual machine planning and failover method for high availability at a virtual machine (VM) level in a data center. The solution is implemented in IBM's Cloud Managed Services (CMS) enterprise cloud offering for rapid failover in large data centers with a large number of servers, VMs, and disks. The failover system enables failover-time planning and execution and keeps the recovery time within limits of service level agreement (SLA) allowed time budget. The initial serial failover time is reduced by a factor of up to 11 for parallel implementation, and by a factor of up to 44 for parallel failover - parallel storage mapping implementation.
