Points of Delivery (PODs)
There are multiple POD (Point of Delivery) types for Cisco IAC 4.2:
Compute POD
Network POD
Service Resource Container
Compute PODs let you to specify compute infrastructure. For example, in the case of the Cloud Infrastructure Type,
VMware vCenter Server, the Compute Pod has selections for Network Pod, vCenter instance, DataCenter, UCS Manager,
as well as Physical Server Provisioning selections. They work together to associate and assemble Compute and Network

Compute POD
Cisco IAC 4.2 models these Compute PODs so it understands how it is that various infrastructure is associated to other
infrastructure, so it can empower the cloud administrator with common tools of capacity management of that
infrastructure.
