As an IBM WebSphere CloudBurst user, you create patterns and deploy them into a private cloud. These patterns are complete representations of IBM WebSphere Application Server environments and can include many different parts, such as a deployment manager, custom node, administrative agent, and more. Each of these parts maps to a unique virtual machine, and that virtual machine is created from a virtual image. Specifically, the virtual machine is created from an IBM WebSphere Application Server Hypervisor Edition virtual image, which contains the operating system, WebSphere Application Server, and IBM HTTP Server, all pre-installed, pre-configured, and pre-tuned. However, this image does not contain other customizations or content that might be required for your specific environment. This article describes how easy it is to customize the WebSphere Application Server Hypervisor Edition virtual image to meet your application environment’s specific needs.
