Which action can the Hybrid Cloud Manager perform?

Cross vCenter vMotion between distinct Single Sign-On domains is a native vSphere feature, not a capability specific to or provided by Hybrid Cloud Manager.

Hybrid Cloud Manager does not provide a unified management interface for both vCloud Air and Amazon Web Services EC2 - it is scoped to vCloud Air and on-premises vSphere integration.

Hybrid Cloud Manager does not support live vMotion migrations spanning multiple public cloud providers such as AWS and Azure simultaneously - its scope is vCloud Air to on-premises vSphere.

Hybrid Cloud Manager is purpose-built to provide bidirectional workload migration between vCloud Air and on-premises vSphere environments, allowing administrators to move VMs from vCloud Air back to local infrastructure. It leverages vMotion-based technology to accomplish live migrations across the hybrid boundary without requiring downtime. This repatriation capability is a core documented function of the product.
