This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of multiple hosts running vSphere and managed by one or several instances of vCenter. It is understood that you do not want to abandon your investment in VMware by retooling the entire stack. You want to continue managing your infrastructure with already familiar and powerful VMware tools, such as vSphere and vCenter Operations Manager. Your goal is to create a self-service cloud environment on top of your vSphere infrastructure to provide your users with a simple cloud interface featuring elasticity, multi-tenancy and self-service provisioning.
