As a service provider, one of the most important aspects of planning for the Physical Architecture portion of a migration is capturing information about the required capacity to support new tenants along with their migrated and newly deployed workloads. To gather this information from customer premises running physical or virtual workloads, VMware provides a tool called Capacity Planner. The data captured from Capacity Planner is useful in understanding consolidation ratios when the source workloads are running on physical hosts, and potential over-commitment scenarios that can be used for a subset of applications depending on tenant resource allocation models available in the VMware Cloud Provider offerings.

Capacity Planner has a SaaS portal at Error! Hyperlink reference not valid. that presents findings from infrastructure utilization measurements. VMware PSO offers a Virtualization Assessment package built around Capacity Planner that can help provide optimal readiness for tenant migration efforts. VMware Solution Providers can also use Capacity Planner and this service model to deliver a similar service. More information can be found at the Capacity Planner product page.
