Part 4: WebSphere in Production Deployments


Chapter List

Chapter 12: Deployment Topology
Chapter 13: Securing your Enterprise
Chapter 14: WebSphere Administration
Chapter 15: WebSphere Summary

If you have got through the preceding parts of this book, then you should know everything you need to build an application to be hosted on WebSphere Application Server. You are now ready to put your application into a production environment.

This part of the book will help you understand how to set up a WebSphere production environment. It begins by understanding the parts of a WebSphere topology and the variations that you can apply to the structure of your information system. The topology chapter will explain how to put together a network of application servers, deployment managers, edge servers, and HTTP servers to achieve your objectives. It will explain the clustering and other topological constructs used by WebSphere.

The most time and resource consuming aspect of putting an application into production is managing it. We go on, in this part of the book, to explain the administration model for the WebSphere environment. We describe the overall architecture for management, walk you through the administration user interface for many common tasks, and spend an entire chapter describing how to program an administrative application – one that can be used to administer the WebSphere Application Server environment. Through this discussion, we will help differentiate between middleware management and enterprise system management. An appendix has been included at the end of this book with a complete enumeration of the command-line, scripting, and Ant services that are provided by WebSphere.

Of course, no production environment would have any value to you unless you could secure it. While its position within this book might suggest otherwise, security has not been an after-thought in the WebSphere programming model – rather, the security model is built right into the Java and J2EE programming model, and has been incorporated throughout the WebSphere runtime.

Finally, to our own dismay, there is no way we could cover everything there is to say about WebSphere in this one book. We conclude this book with a brief look at the other important features of WebSphere.
