PeopleSoft Architecture Fundamentals

Your PeopleSoft application runs within the PeopleSoft Internet Architecture (PIA), which requires a variety of software and hardware elements, including:

• relational database management system (RDBMS).

• application server(s).

• Process Scheduler server(s).

• web server(s).

• web browsers.

It's important to understand the role of each element before you can decide which configuration options will work best for your implementation. The following diagram illustrates, at a high level, the physical relationship between the basic elements of the PeopleSoft architecture:

The browser sends requests to the web server, which transmits the request to the application server, which generates the SQL to run on the database.

Configuring the PeopleSoft infrastructure is not just about enabling internet application deployment through a browser. PeopleSoft enables you to take advantage of numerous PeopleSoft intranet, internet, and back-end solutions, including:

• Integration Broker, our service oriented architecture (SOA).

• PeopleSoft Interaction Hub.

• Feeds Framework.

• Search Framework.

• Performance Monitor.

All of these additional technologies stem from the basic architecture depicted in the previous diagram.
