There are two components to the solution architecture:

  • On-premises vSphere cluster (Site A and Site B)
  • Stretched Clusters for VMware Cloud on AWS

 

Figure : On-Premises vSphere Cluster with Connectivity to Stretched Clusters for VMware Cloud On AWS

 

The on-premises setup has a two-site vSphere cluster configuration:

  • Site A runs Production workloads
  • Site B runs Dev , Test and Disaster Recovery (DR) workloads
  • Both Site A and Site B are in Hybrid Linked mode.
  • Site A and Site B vSphere clusters have access to dedicated storage

 

Site A comprises of a 4-node vSphere 6.7 cluster:

  • Each ESXi server is a Dell PowerEdge R730xd Rack Server with 2 sockets , 14 cores each with
    Intel® Xeon® Processor E5-2695 v3 at 2.30GHz with Hyper-Threading Technology and 384GB of RAM.
  • All ESXi servers has access to a NAS storage

 

Site B comprises of a 4-node vSphere 6.7 cluster:

  • Each ESXi server is a Dell PowerEdge R630 Rack Server with 2 sockets , 14 cores each with
    Intel Xeon Processor E5-2680 v4 at 2.40GHz with Hyper-Threading Technology and 256GB of RAM.
  • All ESXi servers has access to a NAS storage

 

The Stretched Clusters for VMware Cloud on AWS setup has the following configuration:

  • A 6-node stretched cluster for VMware Cloud on AWS is setup across two AZs, 3 servers in AZ us-west-2band 3 servers in AZ us-west-2c.
  • Each ESXi server is an Amazon EC2 i3p.16xlarge with 2 sockets , 18 cores each with Intel Xeon Processor E5-2686 v4 at 2.30GHz with Hyper-Threading Technology and 512GB RAM memory.
  • Storage is provided by the HCI vSAN instance.

 

 

 

An L2VPN is used to extend the on-premises data center on site A to VMware Cloud on AWS to rapidly and easily migrate application workloads from on premises to the VMware Cloud on AWS and back. This leverages the following:

  • NO VM conversions
  • NO application refactoring—therefore noapplication downtime
  • NO networking changes with L2VPN capability between on-premises SDDC and VMware Cloud on AWS
