Figure 2 below shows a three-site lab setup, including on-premises Site A, Site B and VMware Cloud on AWS.
Two separate vSphere clusters are running on Site A and Site B respectively. Site A hosts production workloads while Site B hosts all non-production and disaster recovery (DR) workloads.
Both Site A and Site B are in hybrid linked mode. Site A is connected via Layer 2 VPN to VMware Cloud on AWS. Site B is connected via HCX to VMware Cloud on AWS.
Connectivity between on-premises and VMware Cloud on AWS is 10G Direct Connect and is shared between the various lab activities and VMware research and development.
The VMware Cloud is essentially in a stretched cluster deployment, a 6-node stretched cluster for VMware Cloud on AWS across two availability zones (AZ), with three servers in AZ1 and three servers in AZ2. Storage in VMware Cloud in AWS is provided by the hyperconverged infrastructure (HCI) vSAN instance.
Figure 2. Three-Site Lab Setup (Site A, Site B, and VMware Cloud on AWS)
HCX pairing is configured between Site B and VMware Cloud on AWS with bi-directional migration between on-premises and VMware Cloud on AWS.
Site B contains five single-instance database VMs:
Site B also contains a two-node Oracle RAC ‘TESTRAC’ setup with two VMs: testrac1 and testrac2.
