Getting Your Hands Dirty with Load Balancing

What Does the Integrated Load Balancer Do?

According to the Oracle Solaris 11 documentation, the Integrated Load Balancer (ILB) intercepts incoming requests from clients, decides which back-end server should handle the request based on load-balancing rules, and then forwards the request to that server. By spreading one server's work load across multiple servers, ILB improves reliability, minimizes response time, and improves performance of the server.

The documentation describes features, components, how it works, and even the command line interface. The docs help you understand what your load balancing toolset is, but if you want to get your hands dirty, try this:

Hands-On Lab - Deploying the Integrated Load Balancer in 60 Minutes

by Amir Javanshir

This is a cool lab because it walks you through the steps that set up an environment that enables you to play with the load balancer. The steps consist more or less of:

  • Installing Solaris
  • Setting up the virtual switches and their VNICs
  • Configuring the zone for the load balancer, including its access to the VNICs
  • Cloning that zone into three other zones
  • Configuring each cloned zone to run Apache Tomcat
  • Installing the load balancer on the first zone

Once the environments are set up, the lab walks you through several exercises to help you become familiar with the different ways in with the load balancer monitors and manages traffic. This lab is a whole lot of fun.
