A VMware vSphere Distributed Switch™ (VDS) acts as a single virtual switch across all associated hosts in the data cluster. This setup enables VMs to maintain a consistent network configuration as they migrate across multiple hosts.
For on-premise Site A, VDS SiteA-10g-dVS uses 4 x 10GbE adapters per host
A port group defines properties regarding security, traffic shaping, and network adapter teaming.
The following distributed switch port groups were created for Oracle RAC and Oracle Data Guard traffic to balance traffic across the available uplinks:
For on-premise Site B, VDS SiteB-10g-dVS uses 2x 10GbE adapter and 2 x 1GbE adapter per host

The following distributed switch port groups were created for on-premise Oracle RAC and Oracle Data Guard traffic to balance traffic across the available uplinks:
For VMware Cloud on AWS, VDS vmc-dvs is as shown below

The following distributed switch port groups were created for Oracle VM traffic between on-premises site A and VMware Cloud on AWS:
vSphere vMotion enables live migration of running—that is, powered on—VMs from an on-premises host to a host in VMware Cloud on AWS, with zero downtime for the application (less than 1 second switchover time), continuous service availability, and complete transaction integrity. Furthermore, by enabling certain advanced configurations,
vSphere vMotion migration between on-premises VMs and VMware Cloud on AWS can be enabled across various VDS versions.
