Introduction
The WSO2 Application server is used for hosting, deploying and managing applications, built on the WSO2 Carbon platform. A detailed documentation of the Application Server can be found here.
As is the case with other WSO2 products, multiple instances of the Application Server can be installed in a cluster. When in a cluster, the work is shared between the multiple instances although it appears as if though there is only a single instance of the Application Server (AS).
In this tutorial, we will be using AWS EC2 instances to create a AS cluster. The EC2 instances will be Ubuntu based. We’ll be creating a cluster of 3 AS nodes, using Nginx for load balancing and MySQL for storing the user management and registry data of the AS. More information on load balancing can be found here and here.
