To conduct our evaluations, we established metrics, selected a video streaming application and conducted experiments on different architectures covering OpenSAF in physical and virtual machines, the VMware HA and VMware FT. Our work aims at comparing virtualization solutions, VMware, with OpenSAF from the high availability perspective, and proposes appropriate combinations to take advantage of the strengths of both solutions. At the same time the SAForum specifications and OpenSAF as a compliant implementation offer a standard based open solution for service high availability. There are some availability solutions developed by virtualization vendors like VMware HA and VMware FT. Availability of the virtual machines along with the availability of the hosted software components are the fundamental ingredients for achieving highly available services in the cloud. Virtualization is one of the key enablers of the cloud infrastructure.
