This article will explain to you how to config loadbalancer through vCloud Director. Information about configuration dan type of loadbalancer can read on Overview Loadbalancer

Preparation

Before using this guide, please ensure these following:

• You have subscribe Virtual Data Center
• You have deployed more than 1 VMs
• Understanding about logical loadbalancer

Guide

A. Pools Tab 

Shows an overview of the selected Network Interface and lets you configure and/or edit the Network as selected from the Drop Down.

1. Clicking on the Load Balancer Tab of your vDC you will see the options listed below. Button to Enable/Disable the Load Balancer (default is disabled)

2. Once enabled the Configuration Tabs will appear from which you configure the details required to get the Load Balancing function working for your service workload. 

• Pools: You can add a server pool to manage and share backend servers flexibly and efficiently. A pool manages load balancer distribution methods and has a service monitor attached to it for health check parameters. 
• Application Profiles: You create an application profile to define the behaviour of a particular type of network traffic. After configuring a profile, you associate the profile with a virtual server. The virtual server then processes traffic according to the values specified in the profile. Using profiles enhances your control over managing network traffic and makes traffic-management tasks easier and more efficient. 
• Application Rules: You can write an application rule to directly manipulate and manage IP application traffic. 
• Monitors: You create a service monitor to define health check parameters for a particular type of network traffic. When you associate a service monitor with a pool, the pool members are monitored according to the service monitor parameters. 
• Virtual Servers: Add an NSX Edge internal or Uplink interface to act as the virtual server for the Load Balances Service. 

3. To create a new Load Balancer Pools, click on the Add Pool Button.
