Lab 07 - Inter-SDDC and Native VPC Connectivity



An SDDC deployment group uses VMware Transit Connect to provide high-bandwidth, low-latency connections between SDDCs in the group and to other VPCs in the same region. You can also add a Direct Connect Gateway (DXGW) to provide centralized connectivity to your on-premises SDDCs.

An SDDC deployment group (SDDC Group) is a logical entity designed to simplify the management of your organization's VMware Cloud on AWS resources at scale. Collecting SDDCs into an SDDC Group provides several benefits to an organization with multiple SDDCs whose workloads need a high-bandwidth, low-latency connection to each other. All network traffic between group members travels over a VMware Transit Connect network. Routing between compute networks of all SDDCs in a group is managed automatically by VMware Transit Connect as subnets are added and deleted. You control network traffic among group member workloads with compute gateway firewall rules.

VMware Transit Connect is a VMware Managed Transit Gateway. It Eliminates the overhead of self-deploying and managing complex configurations to establish a connectivity fabric across VMware Cloud on AWS SDDCs, AWS VPCs, and on-premises environments.

VMware Transit Connect easily enables connectivity across environments and adds networks with automatic set up of all the necessary routing policy configuration, transparent to the user. The solution is based on the highly available AWS Transit Gateway. It integrates with AWS Direct Connect Gateway to simplify connectivity to on-premises data centers.

Any organization member who has a VMC service role of Administrator or Administrator (Delete Restricted) can create or modify an SDDC Group.

In this lab, we will first create an SDDC Group with a single SDDC, the purpose of this exercise is to show that an SDDC group can contain a single SDDC, but also to highlight that the VMware Transit connect of the SDDC Group can be used to allow high-bandwidth, low-latency connectivity from SDDC(s) in a group to Native AWS VPC(s). We’ll later I the lab, create a new SDDC Group, and populate it with 2 SDDCs.


Task 1 - Create a Single SDDC SDDC Group


In the Google Chrome Browser from the VDI desktop

  1. Click the VMware Cloud SDDC bookmark
    • Login as vmcexpert#-xx@vmware-hol.com (Where # is the Environment ID and xx is your student number) i.e. [email protected]
    • Password = VMware1!
  2. Navigate to the SDDC item in the menu. You should see both your SDDC and your partner's SDDC
  3. In the top right, Click Actions
  4. Under the Actions Dropdown Click Create SDDC Group
  5. In the Name and Description page Name the Group vmcexpert#-XX-SDDC-Grp (Where # is the Environment ID and xx is your student number)
  6. Click Next


  1. On the Membership page Select <your SDDC> 
    NOTE: Only add your Student SDDC to the group
  2. Click Next
  3. on the  Acknowledgment page Check the Configuring VMware Transit Connect for your group will incur charges per attachment and Data Transfer checkbox
  4. Click Create Group
  5. Monitor the Group creation status (this could take up to 10 minutes to complete)
  6. While you are waiting, review the blue box below and explore the SDDC Groups tab
  7. Click View Details once the status changes to Connected

While waiting for the process to complete, let’s review the SDDC Group tabs

vCenter Linking Tab  Allows Cloud administrator to log in as [email protected] and use the vSphere Client to manage all the vCenter Server systems in the group. If the [email protected] account configures these systems to use single sign-on, then users with accounts in that single sign-on domain can access all the linked systems in the group.

After vCenter linking has been enabled in an SDDC group, the vCenter Server systems in SDDCs added to the group are linked automatically, and vCenter Server systems in SDDCs that are removed from the group are unlinked automatically.

Direct Connect Gateway Tab  After you create an SDDC Group, you can attach an AWS Direct Connect Gateway to it to support high-bandwidth, low-latency connections to your on-premises SDDC.

VMware Transit Connect handles all compute and management network traffic among SDDC group members. Many SDDC group members will also need to make network connections to external endpoints such as on-premises SDDCs, VPCs outside the group, and AWS services that run in them. To enable these kinds of connections, associate an AWS Direct Connect Gateway with the group's VMware Managed Transit Gateway.

Attaching a Direct Connect Gateway to the SDDC group is a multi-step process that requires you to use both the VMC Console and the AWS console. You use the VMC Console to make the VTGW (an AWS resource) available for sharing. You then use the AWS console to accept the shared resource and associate it with the Direct Connect Gateway you'd like to attach to the SDDC Group.

VPC Connectivity Tab  Once the SDDC Group has been configured, you can add existing Native AWS VPC to the group. Doing so allows the VMware Transit connect to establish and manage a High-bandwidth, low-latency connection between the SDDC and the Native VPC(s).

Routing Tab  The Routing tab displays all of the learned routes to the VMware Transit connect as well as all of the Advertised routes from the Transit Connect.

Note: SDDC Groups will typically include 2 or more SDDCs and not a Single SDDC as we have done in this task. The only exception is when you have one or more Native AWS VPC with Services you need to consume in your SDDC or vice-versa and/or connect your On-Premises to your SDDC(s) via a Direct Connect Gateway.

Task 2 - Connect a Native VPC to your SDDC Group

Task 2.1 - Associate you AWS account with the SDDC Group
