The virtual network design example illustrates an implementation of a management application virtual network for the management components in this validated design.

An example for implementing a management application virtual network is the network for vRealize Automation, but the setup of the application virtual networks of any other 3-tier application looks similar.

Figure 1. Detailed Example of vRealize Automation Networking




The example is set up as follows.

  • You deploy vRealize Automation on the application virtual network that is used to fail over applications between regions. This network is provided by a VXLAN virtual wire (orange network in Detailed Example of vRealize Automation Networking).

  • The failover network that is used by vRealize Automation connects to external networks by using NSX for vSphere. NSX ESGs and the UDLR route traffic between the application virtual networks and the public network.

  • Services such as a Web GUI, which must be available to the end users of vRealize Automation, are accessible using the NSX Edge load balancer.

You map each application virtual network to an IPv4 subnet according to your environment and availability of IP subnets. For example, you can implement the following configuration:
