The following deployment use case depicts a service provider architecture that spans five geographically separated data centers with a requirement to maintain a vCenter Single Sign-On domain. The sites with larger vSphere deployments host multiple load-balanced Platform Services Controllers supporting multiple vCenter Server instances with additional VMware products, such as vRealize Operations 6.0. Smaller sites have been deployed with a single vCenter Server Appliance with an embedded Platform Services Controller for an efficient, small footprint design.
