Virtualization has transformed enterprise data centers and server rooms around the world. The economics—hardware, facilities, power, cooling and more—are compelling, but SMBs struggle with different challenges and constraints than enterprises. The biggest difference is resources: With fewer staff and lower budgets, SMBs need better availability, reliability and security in their virtualization platforms.
It’s often difficult for businesses to evaluate competing virtualization platforms. Despite superficial similarities, different providers’ platforms are far from identical. Fundamentally different development goals, design philosophies, target markets, core and supporting technologies, feature sets, tools, bundles and support offerings have real consequences for implementation success.
This paper compares the VMware vSphere™ virtualization platform to two alternatives—Microsoft® Hyper-V™ Server and Citrix® XenServer®—focusing on features and issues that affect SMB outcomes.
