Learn HCX – Topic 2 – What are the Components of HCX?

In my last blog we have understood About HCX, Why do we need HCX , What are the benefits we can avail from HCX.

Now its time get some more details about HCX. What are  their Components and their work?

HCX has concept of source and target, Target we take it as a cloud side which is basically controlled and managed by Client side install of HCX. The other side is the HCX install on On-premises side which is basically a Master which controls cloud side  HCX via vCenter web client UI snap-in.

Now lets cover  four important components in HCX which is backbone of migration of workload.

 HCX Manager:

First we need to install HCX manager to cloud side for VMware solutions, Its a OVA file specific to cloud side in conjunction with an NSX edge load balancer firewall which is configured specifically for the HCX role.

Then, On-Prem HCX manager is an OVA image file which provides the UI functionality for Controlling HCX. The client side HCX manager is responsible for registration with the target side HCX manager and creating a management plane between the on-premises and target side.

Fleet components:

HCX WAN Interconnect (CGW)

This is commonly known as Cloud gateway which is basically create an encrypted tunnel for workload migration (be it vMotion or bulk migration ) over the internet and private lines to the cloud side while providing  traffic engineering and virtual machine mobility.

HCX WAN optimizer

It works along with CGW, Its a Silver Peak™ WAN optimization appliance use for deduplication and line conditioning  and bring the performance to LAN environment.

HCX Layer two extension(L2C):

It also create an encrypted tunnels for the data and control plane corresponding to stretched layer 2 traffic and helps to allows keeping the same IP and MAC addresses during a Virtual Machine migration.Network Extension with Proximity Routing  ensures that forwarding between virtual machines connected to extended and routed networks, both on  premises and in the cloud, is symmetrical.
