The Management, Resource, and Edge Pods are deployed in each data center that is part of a site. Pods that belong to a site can be scaled to meet the use cases and requirements of their data centers.

Resource Pods in each data center are sized to meet the scale and traffic requirements of the VNFs and other data plane functions.

Respectively, a pair of availability zones should be created in each site for redundancy and fault tolerance. A group of homogenous hosts, also called host aggregates should be mapped across the availability zones. A single tenant (Project and Tenant vDC) map to the host aggregates to deploy workloads for control and user plane functions.
