Network segments are logical networks for use by workload VMs in the Compute-ResourcePool of the SDDC on VMware Cloud on AWS.

VMware Cloud on AWS supports three types of logical network segments: routed, extended, and disconnected.

  • A routed network segment (the default type) has connectivity to other logical networks in the SDDC on VMware Cloud on AWS, and to external networks through the SDDC firewall.

  • An extended network segment extends an existing L2VPN tunnel, providing a single IP address space that spans the VMware Cloud on AWS SDDC and an on-premises network.

  • A disconnected network segment has no uplink and provides an isolated network accessible only to VMs connected to it. Disconnected segments are created when needed by HCX. You can also create disconnected network segments and can convert them to other segment types.

SDDCs on VMware Cloud on AWS does not contain a default network segment, so you must create at least one for your workload VMs. You can use the VMC Console to create network segments or delete network segments that are no longer in use.

When you create a network segment, ensure that it does not overlap your management network or any of the subnets in your connected Amazon VPC.
