WebSphere deployment architecture
This section provides an overview of the IBM WebSphere Application Server v7.0 deployment architecture.
RAD v7.5 includes an integrated Application Server v7.0. Administration of the server and applications is performed by using the WebSphere Administrative Console for such configuration tasks as:
| 
|
| J2C authentication aliases |
|
|
|
| Data sources |
|
|
|
| Service buses |
|
|
|
| JMS queues and connection factories |
Due to the loose coupling between Application Developer and Application Server, applications can deploy in the following ways:
| Deploy from an Application Developer project to the integrated Application Server v7.0. |
|
| Deploy from an Application Developer project to a separate Application Server runtime environment. |
|
| Deploy through an EAR to an integrated Application Server v7.0. |
|
| Deploy through an EAR to a separate Application Server runtime environment. |
Administration of the application server is performed through the WebSphere Administrative Console that runs in a Web browser.
In addition, the Application Server v7.0 can obtain an EAR from external tools and be loaded into Application Developer v7.5 or Application Developer Assembly and Deployment (RAD-AD). Application Developer or RAD-AD optimize the EAR and a new EAR is saved to deploy to the application server.
The Assembly and Deploy function replaces the former Application Server Toolkit (AST) v6.1 function. Assembly and Deploy is licensed as part of the WebSphere Application Server v7.0. It includes a superset of the older AST functionality and is fully integrated within the Application Developer v7.5 tooling. The remaining Application Developer v7.5 functions are included on a trial basis and can be easily purchased through a downloadable license key.
A diagram of the deployment architecture and the various mechanisms to deploy out an application are provided in Figure | 6-4.
Details on how to configure the servers in Application Developer v7.5 are documented in Chapter | 2, Servers and server configuration.
