Basics

This chapter states the concepts of Plesk plug-in technology known as Plesk Modules:

• The Overview section shows the purpose of modules in Plesk architecture, explains the difference between modules and other ways of extending the logic of Plesk, and shows why modules are more useful for the customer.
• The How a Module Builds into Plesk Architecture section gives a common idea of what a module presents, how it is structured, and how this structure mounts in the file and folder structure of Plesk.
• The Plesk Modules Support Architecture section explains how Plesk supports modules and what internal mechanisms of Plesk are involved. This section specifies the boundary between the area of Plesk support and the area of the module's activity (with regard to each operation that can be performed against the module).
