Global Server Load Balancers

From LB Wiki

Jump to: navigation, search

Global Server Load Balancers distribute traffic to multiple geographically locations. The decision on where to send traffic is typically based on:

  • Availability of the geographic location
  • Connectivity of the client to the multiple locations (best connectivity is preferred, and there are many methods for determining which geographic location has the best relative connectivity

At these datacenters, there is usually a local server load balancer as well, to distribute traffic to the local servers.

Server load balancers distribute load to servers, and global server load balancers load balance to servers directly or (more likely) local server load balancers (or a combination thereof).
