This design uses two separate NSX instances per region. One instance is tied to the Management vCenter Server, and the other instance is tied to the Compute vCenter Server. Deploy and configure the NSX instance for the management cluster in Region A.


For this implementation NSX Manager and vCenter Server have a one-to-one relationship. For every instance of NSX Manager, there is one connected vCenter Server. 


After the NSX Manager is successfully connected to the Management vCenter Server, you must promote it to the primary role and deploy the three NSX Controller nodes that form the NSX Controller cluster.


You must install the NSX kernel modules on the management cluster ESXi hosts to be able to use NSX.


After all the deployment tasks are ready, you must configure the NSX logical network. 


When an authorized change is made to a host, the Host Profile must be updated to reflect the changes.


You configure load balancing for all services and components related to Platform Services Controllers (PSC) using an NSX Edge load balancer. 


NSX for vSphere creates a network virtualization layer on top of which all virtual networks are created. This layer is an abstraction between the physical and virtual networks. You configure NSX dynamic routing within the management cluster, deploying two NSX Edge devices and a Universal Distributed Logical Router (UDLR).


Configuring a distributed firewall for use with your SDDC increases the security level of your environment by allowing only the network traffic that is required for the SDDC to run. The firewall rules you define allow access to management applications.


Test the configuration of the NSX logical network using a ping test. A ping test checks if two hosts in a network can reach each other.


Deploy the application virtual networks.


Deploy a load balancer for use by management applications connected to the AVN, Mgmt-xRegion01-VXLAN.
