In the previous blog post, we created a simple HelloWorld example in AWS. We did the bare minimum (as any HelloWorld example should!) by taking advantage of a default VPC, Subnet, NACL, and Internet Gateway but, by necessity for our example, creating a custom Security Group.
In this tutorial, we will shy away from defaults and create a VPC from scratch. Again, this is done in the guise of HelloWorld.

Setting up multiple instances of Tomcat
With multiple tomcat instances, each can run in its own JVM, have its own configuration and can be started/stopped independently.
One approach to doing this would be to have multiple, full tomcat installations. This article instead details how to install tomcat once (in CATALINA_HOME) but have multiple independent instances (by utilizing CATALINA_BASE). This is a more streamlined approach that makes creating multiple instances easier and also simplifies upgrades/rollbacks of tomcat.
