An Oracle Cloud VMware Solution software-defined data center (SDDC) contains the resources required for a functional VMware environment. Instances in an SDDC (see EsxiHost) run in a virtual cloud network (VCN) and are preconfigured with VMware and storage. Use the vCenter utility to manage and deploy VMware virtual machines (VMs) in the SDDC.
The SDDC uses a single management subnet for provisioning the SDDC. It also uses a set of VLANs for various components of the VMware environment (vSphere, vMotion, vSAN, and so on). See the Core Services API for information about VCN subnets and VLANs.
