Ruth Willenborg is a Senior Technical Staff Member in IBM's WebSphere Technology Institute where she is currently working on WebSphere cloud computing and virtual appliance initiatives and is the technical evangelist for the new IBM WebSphere CloudBurst Appliance. Prior to her work on virtualization and appliance initiatives, she was the manager of the WebSphere Performance team responsible for WebSphere Application Server performance analysis, performance benchmarkingm and performance tool development. Ruth has more than 20 years of experience in software development at IBM and is co-author of Performance Analysis for Java Web Sites (Addison-Wesley, 2002) and numerous articles on both WebSphere performance and using WebSphere with virtualization technologies.

Summary:  In this tutorial, the authors demonstrate how to use WebSphere® CloudBurst to build patterns you can use to represent the configuration of both your application and application infrastructure. They also show you how to use these patterns to consistently deploy the application environment as it moves through the four life-cycle stages — development, test, QA, and production. The tutorial offers a complete, step-by-step example of using patterns to handle changing topologies, underlying platform architectures, and configuration properties.

Showtime! Moving to production

You're at the point where it is time to put your brand new Account Management application into production and open it up for enterprise use. To accomplish this you can use the same Account Management Cluster — QA pattern created earlier or if organizational processes dictate, you can simply clone it and create a new pattern with a new name. Nothing about the makeup of the pattern will change. In fact, in order to deploy your Account Management cluster environment into production, you only need to make two familiar changes:

  1. The application binaries should be retrieved from a different repository.
  2. The data source should be configured to refer to a different database instance.

This means you simply change the configuration data at deploy time as you have done previously.

Deploying the pattern to production

This is all it takes to move your application environment from quality assurance into a production environment! Once the deployment process is complete and the virtual system started, you can access the WebSphere Application Server administration console just like you did for previously deployments and you can manage the virtual system in WebSphere CloudBurst in the same manner as you managed virtual systems deployed on the VMware ESX platform.

Not only is the end-user experience consistent with respect to creating and deploying patterns for different platforms, the experience is the same when managing the resultant virtual systems regardless of the type of infrastructure on which the virtual machines are hosted.

How does it feel? You have moved an Account Management application from development to test to quality assurance and finally into production. Each migration action was little more than a combination of drag-and-drop actions paired with tweaks to deploy-time configuration data. In addition, each time you performed a migration task in minutes.
