The virtual network design example illustrates an implementation for a management application virtual network.

Detailed Example of Application Virtual Networking shows an example for implementing a management application virtual network. The example service is vRealize Automation, but any other 3-tier application would look similar.

Figure 1. Detailed Example of Application Virtual Networking

Application Virtual Network Components and Design

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 GUID-074E1E04-5DB5-4595-9E7D-78E50EB2CB52.html#GUID-074E1E04-5DB5-4595-9E7D-78E50EB2CB52__ID-fig-00000006).

  • The network that is used by vRealize Automation connects to external networks through 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 via the NSX Edge load balancer.

The following table shows an example of a mapping from application virtual networks to IPv4 subnets. The actual mapping depends on the customer environment and is based on available IP subnets.


The following IP ranges are an example. Your actual implementation depends on your environment.
