A VMware Cloud on AWS Software-Defined Data Center (SDDC) is a collection of bare-metal hosts running a standard set of VMware software components, including vCenter, vSAN storage, and NSX software-defined networking.

Each SDDC runs in an Amazon Virtual Private Cloud (VPC) and provides a full VMware stack, including vCenter, NSX software-defined networking, and storage, and one or more ESXi hosts that provide compute and storage resources to your workloads.
