  • The source HCX Manager makes outbound HTTPS connections to the site paired destination HCX Manager systems.

  • The VMware Cloud on AWS URLs are listed in vmc.vmware.com, under SDDCs > Settings.

  • Ensure the VMware Cloud on AWS management firewall allows inbound HTTPS connections from the on-premises HCX Connector and from the User systems that access the interface.

▢ HCX Activation / Licensing:

  • Activation keys for the HCX Connector system on-premises are generated in VMware Cloud on AWS.

  • To generate a key, open add-ons tab to open HCX. Use Activation Keys > Create Activation Key > HCX Connector to generate a key for the on-premises HCX system.

  • The HCX in the VMware Cloud on AWS SDDC instance activates when the service is enabled.

Proxy requirements

If a proxy server is configured, all HTTPS connections are sent to the proxy. An exclusion configuration is mandatory to allow HCX Manager to connect to local systems.

The exclusions can be entered as supernets and wildcard domain names. The configuration can encompass these settings:

  • vSphere

    Management Subnets.

  • NSX Manager if present.

  • Internally addressed site pairing targets.

  • You can use the RFC 1918 IP block, along with the internal domain name, as the exception configuration.

For example: 10.0.0.0/8, *.internal_domain.com

Not applicable.

Planning the Compute Profile Configuration

A Compute Profile contains the catalog of HCX services and allows in-scope infrastructure to be planned and selected prior to deploying the Service Mesh. The Compute Profile describes how HCX deploys services and service appliances when a Service Mesh is created.

A Compute Profile is required in the on-premises HCX Connector.

A Compute Profile is pre-created in the VMware Cloud on AWS SDDC as part of enabling the HCX Add-on.

""

Review the table for a checklist of Compute Profile configuration items. For each row, the table describes how that information is used in the source and the destination Compute Profile.

On-premises Compute Profile

▢ Compute Profile Name

  • Using meaningful names simplify operations in multiple Compute Profile deployments.

  • The Compute Profile configuration is created automatically in the SDDC HCX system when HCX is enabled.

▢ Services to activate

  • Services are presented as a catalog, showing available capabilities based on licensing.

  • This can be used to restrict the individual HCX services that are activated.

  • All HCX services are activated in the SDDC Compute Profile.

▢ Service Resources (Data Center or Cluster)

  • Every cluster that contains virtual machines used as a Service Cluster in the Compute Profile.

  • The SDDC Compute Cluster is assigned as the HCX Service Cluster.

  • The SDDC Management Cluster is a Service Cluster.
