Understanding PeopleSoft Pure Internet Architecture
PeopleSoft PeopleTools is the technical foundation of the PeopleSoft software and the Oracle’s PeopleSoft Pure Internet Architecture. As suggested by the name, the PeopleSoft Pure Internet Architecture lets you use PeopleSoft applications in a purely Internet environment.
The PeopleSoft Pure Internet Architecture is a server-centric execution architecture for deploying Internet applications to end users who access the applications through a web browser. These Internet applications are built using PeopleSoft PeopleTools. The following diagram illustrates the various servers involved in the PeopleSoft Pure Internet Architecture and the protocols they use to communicate:
Components and communication protocols of PeopleSoft Pure Internet Architecture
There are several key concepts to take away from the above diagram:
• Endusersaccess the applications through a web browser.
• Thearchitecture is very server centric.
The heart of the architecture is the PeopleSoft Internet application server that consists of the web serverand the application server.
• The above architecture supports all of your end users.
The only users who will require Microsoft Windows machines and client configurations will be system administrators and developers who use the PeopleTools Development Environment.
The PeopleTools Development Environment is used by developers and system administrators, who are typically a very small percentage of the overall user base. The following diagram illustrates the connection between the PeopleTools Development Environment, the application server, and the database server.
How the PeopleTools Development Environment communicates with the application server and database server
This is just the Microsoft Windows-based PeopleTools Development Environment that can be deployed in either two- or three-tier mode.
In other words, with the PeopleSoft PeopleTools technology, the client platform should be much less of an issue when compared to past PeopleSoft releases. The use of server-centric, browser-based applications in the current PeopleSoft software should allow you to focus primarily on the server platforms. All the client machine needs is a standard web browser.
