Virtual Machine Resiliency Management System for the Cloud

This article presents a scalable parallel virtual machine (VM) resiliency management system for the cloud environment. It describes two complementary mechanisms for providing resiliency: automated VM restart when a physical server fails unpredictably, and automated evacuation of the VMs from a physical server that is about to fail or needs to be maintained. The solution is suitable for clouds with a large number of physical servers, VMs, disks, networking components, and management tools. This solution has been deployed in IBMs Cloud Managed Services enterprise cloud.
