About VMware HCX

VMware HCX 4.5.1 is available for VMware Cloud on AWS GovCloud deployments only.

VMware HCX delivers secure and seamless application mobility and infrastructure hybridity across both on-premises and in the cloud. HCX abstracts the distinct private or public vSphere resources and presents a Service Mesh as an end-to-end entity. HCX Interconnect can then provide high-performance, secure, and optimized multi-site connectivity to achieve infrastructure hybridity and present multiple options for bi-directional virtual machine mobility with technologies that facilitate the modernization of legacy data centers.

For more information, see the VMware HCX User Guide in the VMware Documentation Center.

Installation and Upgrade

Installing HCX 4.5.1

HCX for VMware on AWS GovCloud installs as an add-on service from the VMware Cloud on AWS GovCloud console. Following the deployment of HCX Cloud Manager in VMware Cloud on AWS GovCloud, you deploy HCX Connector in your on-premises site and connect the two sites as a "site pair." Alternatively, you can create a site pairing between two VMware Cloud for AWS GovCloud deployments in a cloud-to-cloud configuration.

To get started, see HCX for VMware Cloud on AWS GovCloud.

For a sample installation workflow, see the section HCX Installation Workflow for HCX Public Clouds.

Upgrading to HCX 4.5.1

  • Requirements:

    • Upgrading to HCX 4.5.1 from HCX 4.3.9 is supported.

    • All site paired systems must be upgraded.

  • Upgrade snapshots

    • During upgrades to HCX 4.5.1, HCX Manager snapshots are taken automatically.

    • Upgrade snapshots are only taken when an HCX Manager is deployed on the same vCenter Server registered to it. For other deployments, manual snapshots can be taken.

    • HCX retains automatic snapshots for 24 hours before deleting them.

      Note: To restore the HCX Manager from a snapshot, contact VMware Support.
