vCenter Server is a key component of the solution that provides centralized management of VMs in both VMware Cloud Provider and customer locations. Additionally, it is a required component for the use of VMware NSX with vSphere based deployments. While it is possible to have completely separate deployments of vCenter Server with individual PSC and single sign-on (SSO) domains, deploying both vCenter Server instances within the same SSO domain reduces some of the management tasks within the implementation. First, there is the benefit of having a shared view of both vCenter Server instances provided that the user has the required privileges for both. Additional benefits of this configuration are discussed in Section 6, VMware NSX L2VPN Onboarding Scenarios.

With the service provider model, it is common for the end customer to have their own PSC/SSO domains. Where this is the case, the long-distance vSphere vMotion operations must be performed through the API and not through the UI with the federated view of the vCenter Server instances.
