For IT Pros: This page contains information about the Server Load Balancing (SLB) service, how to request SLB service, and how to use the SLB service. Most of this information is for IT professionals; end users will connect to the services using the SLB by the hostname the service advertises.
Server Load Balancing (SLB) is using a device to sit between the customers and multiple instances of your hardware (called real servers in SLB-speak) used by a service. The SLB device presents a single, virtual server front-end to the customers of the service while spreading the actual traffic out to the real servers so that they each take a part of the load. This allows you to give your customers a single name or IP address for your service, even if you have multiple servers. Your customers connect to the Virtual Server IP address that is configured in the load balancer (VIP in SLB-speak), and the load balancer uses the real servers' load and health check information to decide where each user’s connection will go.
For example, if your customers know your service by the name www.test.illinois.edu, and their traffic needs to be balanced to the 3 web servers on the right, your server load balancing configuration might look like this:
SLB is available through the DCL Data Center and the Technology Services portion of the data center in RRB in Chicago.
If you've never used SLBs before, you should setup a meeting with the SLB service manager and make sure you have all the information you need to get started.
