Now let’s look at what’s under the hood.

Key components included as a part of VMware Cloud on AWS Outposts:

  • Industry-standard 42U rack 
    1. Fully assembled and ready to be rolled into final position 
    2. Installed by AWS, plugged into power and network
    3. Centralized redundant power conversion unit and DC distribution system for higher reliability, energy efficiency, and easier serviceability 
    4. Redundant active components, including top of rack switches
  • Dedicated Nitro-based EC2 metal servers with local SSD storage (as per the order)
  • VMware SDDC software – vSphere, vSAN, NSX-T, vCenter Server

Compute: Instance Type and Configuration Options:

VMware Cloud on AWS Outposts supports i3en.metal instance type. Based on the 2nd Generation Intel® Xeon® Scalable Processor, i3en.metal instances are optimized for applications requiring high random I/O access to large amounts of data utilizing storage optimization of VMware VSAN Compression. 

VMware Cloud on AWS Outposts i3en.metal instances provide: 

  • 45.84 TiB (50 TB) raw capacity per host, with an additional 6.55 TiB cache capacity delivered via low latency NVMe SSD storage.  
  • Depending on workload characteristics and FTT/RAID settings, this instance type can deliver up to 34 TiB of usable storage capacity per host.  
  • 96 logical cores or vCPUs especially suited for applications that require increased CPU throughput.  
  • 768 GiB (825 GB) of memory. 

Configuration Options: Customers can choose 3 – 8 hosts configuration per rack. All configurations come with dark host capacity for host remediation, EDRS scale-out, and lifecycle management purposes

Networking- Connectivity options:

  1. Service Link Connection
Connection between VMware Cloud on AWS Outposts and local AWS Region

An Outposts requires a connection back to an AWS region. The connection must be minimum 1GB with sub 150ms of latency. The service link is an encrypted set of VPN connections that are used whenever the Outpost communicates with your chosen home Region – See above. Service link connectivity options include – AWS Direct Connect via Private or Public VIF or internet via your Internet Service Provider 

VMware Cloud on AWS Outposts offers connectivity to regional AWS services over Elastic Network Interface (ENI) or VMware Transit connect. 

Data transfer from VMware Cloud on AWS Outposts to the parent VMware Cloud on AWS supported region incurs no charge. Similar to data transfer charges in AWS Regions, data transfer out charges from the parent availability zone to the VMware Cloud on AWS Outposts is the same as in the AWS Regions. Intra-AZ, inter-AZ and VPC data transfer charges in the AWS Region remain the same

2. LGW – Local Gateway

Connection between VMware Cloud on AWS Outposts and on-premises environment

The local gateway provides a target for on-premises destined traffic. VMware NSX as associated with the SDDC deployed as a part of VMware Cloud on AWS Outposts advertises networks destined for on-premises to the LGW route table – See below

Workload Migration to and from VMware Cloud on AWS Outposts

Customers can deploy new environments on VMware Cloud on AWS Outposts or migrate their existing environment using well-established options such as VMware vMotion and VMware HCX.
