When HCX Migration, Disaster recovery, Network Extension, WAN Optimization services are enabled, HCX deploys Virtual Appliances in the source site and corresponding "peer" virtual appliances on the destination site. The Multi-Site Service Mesh enables the configuration, deployment, and serviceability of these Interconnect virtual appliance pairs with ease.
Multi-Site Service Mesh Benefits
New Configuration Options:
Uniformity: the same configuration patterns at the source and remote sites.
Reusability: Once a compute profile is created, it can be used to connect to multiple HCX sites.
Multisite ready: Compute Profiles and Network Profiles can be shared across multiple sites.
Ease of reconfiguration: New capability to pool datastores or modify them after deploying an Interconnect network structure.
Scale-out deployment: The HCX-IX can be deployed per cluster or a single HCX-IX can be shared across multiple clusters.
Cloud-to-Cloud: Cloud to Cloud capabilities are built on the foundation of the Multi-Site Service Mesh.Important:
VMware currently supports cloud-to-cloud provisioning only in the VMware Cloud on AWS.
Parallel execution ensures faster Interconnect deployments (in under 5 minutes).
The new lockless model ensures parallel configuration of network stretches.
Improved interfaces display a clear deployment diagrams.
New task-tracking features provide incremental details for each step of the progress of operations.
Preview of required firewall rules to avoid configuration difficulties.
Multi-Site Service Mesh Site Pairs
The destination HCX system is registered in the Multi-Site Service Mesh Interface at the source site.
Compute and Network Profiles
The compute profile defines the structure and operational details for the virtual appliances used in a Multi-Site Service Mesh deployment architecture. The compute profile:
Provisions the infrastructure at the source and destination site.
Provides the placement details (Resource Pool, Datastore) where the system places the virtual appliances.
Defines the networks to which the virtual appliances connect.
The following conditions apply when deploying a service mesh network:
The integrated compute profile creation wizard can be used to create the compute and network profiles (or Network Profiles can be pre-created).
HCX Interconnect service appliances are not deployed until a service mesh is created.
A Service Mesh specifies a local and remote Compute Profile pair. When a Service Mesh is created, the HCX Service appliances are deployed on both the source and destination sites and automatically configured by HCX to create the secure optimized transport fabric.
