vRA 7.2 DIG – 06.1, NSX Load Balancer Config

Automation, Cloud, Install Guide, NSX, Tech200, Tech300, Technical, VMware, vRA, vRA DIG

Next we’ll be configuring load balancing and high availability policies for the distributed components. An NSX Edge Service Gateway (ESG) will be providing the load balancing and availability services to vRA as an infrastructure service. vRA supports In-Line and One-Arm load balancing policies. This implementation will be based on an In-Line configuration, where the vRA nodes and the load balancer VIPs are on the same subnet.

(If you do not plan on using NSX for HA services, you can skip this configuration)

 

 

The vRA Load Balancing Guide provides additional details and load balancing guidelines for NSX, F5, and NetScaler.

NSX Load Balancing configuration consists of creating a Application Profile, Health Monitoring policy, Server Pool(s), and a Virtual Server (VIP) per load-balanced pair. These services can be configured after the initial deployment (preferred) to avoid any potential deployment issues related to load balancing config.
