Network Deployment (Distributed operating systems), v8.0 > Product overview and quick start

Fast paths for WAS

Use the paths in this topic to deploy applications quickly and easily. This topic provides links that pinpoint the relevant information for reaching your goals quickly. It also describes the audience roles and tasks assumed by this documentation. The fast paths in this topic are intended to help you gain a little experience. The fast paths do not showcase the advanced product features that some users need or want to use in their production environments.

Deploy any type of application involves the following tasks.

Procedure

1. Install the product.

   The simplest scenario is to perform a typical installation of a single application server.

   We can use the WAS, Express on Linux or Windows operating systems to try out the product. It has a single application server and its Trial program code is available at no cost.

2. Obtain or develop the application.

   In the simplest scenario, you already have a packaged web application that is compliant with Java EE, perhaps from a vendor with whom you work. Other than that, a web application is the most simple type of application to develop. See topics on developing web applications, or refer to product samples.

3. Deploy and test the application.

   In the simplest scenario, you will use the application installation wizard available in the administrative console. See topics on installing applications for a detailed walkthrough of this task. The task describes many contingencies, but many of these steps can be disregarded if:

   • You are deploying a web application.
   • You accept the default settings whenever possible.
   • Your application does not require data access.
   • Your application does not require security.

   Also, in many situations, you do not need to modify the default application server configuration.

4. Administer your deployed application.

   In the simplest scenario, you monitor the application with the Tivoli Performance Viewer functionality built into the administrative console. For an overview of this task, see topics on Monitoring performance.

Results

Now you should have some insight into the task flow for successfully deploying the applications.

To solidify and expand your understanding, view the following table. It shows the user role and task assumptions by which this documentation is organized, for predictability. If you know what role or task you are performing, you can disregard (at least temporarily) documentation that is labeled for other roles or tasks. By their nature, role and task models are simplified compared to reality. Also, one person might perform many roles and tasks in the course of a day.

Mapping of user roles to user tasks. Each user role performs at least one user task.

User role	User tasks
Installer	Install application serving environment Administer applications and environment Migrate deployed applications and their environment
Administrator	Administer applications and environment Deploy applications into production Monitor and tune applications and their environment
Developer	Develop or migrate application code Assemble applications for deployment Deploy applications for testing
Security expert	Secure applications and their environment
Troubleshooter	Use tools to troubleshoot problems
