VMware HCX comprises a virtual management component at both the source and destination sites, and up to three types of VMware HCX Interconnect service appliances. VMware HCX services are configured and enabled at the source site, and then deployed as virtual appliances at the source site, with a peer appliance at the destination site.

VMware HCX Enterprise Manager and VMware HCX Cloud Manager





VMware HCX Manager platform is deployed to the management zone, adjacent to each site's vCenter Server, and provides a single plane for administering VMware HCX. The VMware HCX manager provides a sophisticated framework for deploying VMware HCX service VMs across both the local and remote sites. VMware HCX administrators are authenticated, and each task authorized through the existing vSphere SSO identity sources. VMware HCX mobility, extension, protection actions can be initiated from the VMware HCX User Interface or from within the vCenter Server Navigator screen's context menus.

In the HCX site-to-site Architecture, the HCX Managers have a Source or Destination function. HCX Enterprise Manager is always deployed as the source. HCX Cloud Manager is always deployed as the destination. Same types cannot be paired with each other.

In HCX-enabled public clouds, the cloud provider deploys VMware HCX Cloud. The public cloud tenant deploys VMware HCX Enterprise on premises.

In the NSX Hybrid Connect model (HCX for Private to Private deployments), the tenant deploys both source and destination VMware HCX Managers.

HCX-IX Interconnect Appliance

The HCX-IX service appliance provides replication and vMotion-based migration capabilities over the Internet and private lines to the target site whereas providing strong encryption, traffic engineering, and virtual machine mobility.

HCX-WAN-Optimization Appliance

The VMware HCX WAN Optimization service improves performance characteristics of the private lines or Internet paths by applying WAN optimization techniques like the data de-duplication and line conditioning. It makes performance closer to a LAN environment. It accelerates on-boarding to the cloud using Internet/VPN- without waiting for Direct Connect/MPLS circuits.

HCX Network Extension Virtual Appliance

The VMware HCX Network Extension service provides a late Performance (4–6 Gbps) Layer 2 extension capability. The extension service permits keeping the same IP and MAC addresses during a Virtual Machine migration. Network Extension with Proximity Routing enabled ensures that forwarding between virtual machines connected to extended and routed networks, both on-premises and in the cloud, is symmetrical.
