Elastic Load Balancing (ELB)

This is a service offered by AWS for providing highly available TCP load balancing services for Amazon EC2 instances. They are capable of performing SSL termination and can handle very high loads.

The ELB service can be managed either through the AWS Web Console or by using the ELB API. The ELB API tools are very robust, and are a tremendous asset for managing load balancing services for server and application pools.

There are some caveats that come with the territory (such as hard coded 60-second TCP keep alive’s). The load balancers also operate on pure round-robin. Although they do allow for the end-users to configure many health checking parameters in determining if a server or server service is up, they do not support some of the more advanced load balancing algorithms (like those that can be found on the f5 BIG-IP  platform).

Elastic Load Balancers do serve, however, as a superb, reliable and cost effective method for load balancing distributed web applications on the AWS platform. We know the in’s and out’s – to find out how we can help, use the contact form below to see what we can do for you.
