VMware HCX is an add-on to the VMware Cloud on AWS SDDC. After activating the add-on from the VMware Cloud on AWS Console, the HCX Cloud components are deployed and the HCX plug-in is available in the vSphere Client.


  • The user performing this procedure must have access to the VMware Cloud on AWS console.


  1. Log in to the VMC Console.
  2. Click View Details.

    The SDDC interface opens.

  3. On the Add Ons tab of your SDDC, click Open HCX on the HCX card.

    The VMware HCX interface opens.

  4. Navigate to the SDDC tab and click Deploy HCX and click Confirm to initiate the deployment.

    The VMware Cloud on AWS activation is created and displayed, and the deployment begins. This step takes several minutes to complete. After the deployment is complete, hcx_cloud_manager appears in the vCenter console.

  5. Create a firewall rule to open the necessary ports to access the HCX Cloud Manager.
    1. From the VMC Console, select Networking & Security.
    2. Under Security go to Gateway Firewall and select Management Gateway.
    3. Click Add Rule and create a new inbound firewall rule with these parameters:
      • Source: Where the connection to the HCX manager is coming from.

      • Destination: HCX

      • Services: HTTPS (TCP 443)


      In cloud-to-cloud deployments (where two VMware Cloud on AWS SDDCs are paired) it is required to create an outbound HCX firewall rule. On this rule, set the Source as HCX, the Destination as any, and Service as any.

    4. To save the new rule, click Publish
  6. On the Add Ons tab of your SDDC, click Open HCX on the HCX card.

    A new browser tab opens.

  7. Navigate to the SDDC tab and click Open HCX.

    The VMware HCX Cloud service interface opens.

  8. Enter the cloudadmin@vmc.local user and password and click Log In.


The HCX Cloud Manager UI is available for HCX operations.

What to do next
