Setting up a Load-Balanced Oracle Weblogic Cluster in Amazon EC2

Update (January 29, 2016) – This blog post is six years old and many of the original links are now out of date. Take a look at the newer (albeit not by much) Oracle AMIs page for some alternatives.

Oracle recently released several middleware Amazon Machine Images (AMIs) to the community. I want to point out a detailed blog entry by Paul Parsons from The Server Labs that describes how to run a Weblogic Server on Amazon EC2, incorporating the load balancing feature inside the Monitoring, Auto Scaling and Elastic Load Balancing Service for Amazon EC2.

The following paragraphs are straight out of Pauls full blog post, which of course you should read in its entirety if this topic is relevant to your interests.

Oracle recently made available a set of AMI images suitable for use with the Amazon EC2 cloud computing platform. I found the two images (32-bit and 64-bit) that contain Weblogic (along with Oracle Enterprise Linux 5 and JRockit) the most interesting of the lot. This article will explain how to set up a basic two-node Weblogic cluster using the 32-bit Weblogic image provided by Oracle with an Amazon Elastic Load Balancer (ELB). In future articles, I will demonstrate how to set up a more complicated cluster with Apache Web Server instances balancing the load between many weblogic cluster members.

You can set up a Weblogic cluster in EC2 in very little time which makes it great for testing complicated Weblogic setups without having to mess around on your local machine or trying to scrape together the necessary hardware. This type of configuration would also be suitable for deploying a production application, though youd have to check the licensing implications with Oracle if you wanted to do this.

Note that this article assumes a basic level of familiarity with using Amazon web services.
