This document describes the architecture of the EPiServer platform, with an introduction to the system foundation and related components and products.

The EPiServer platform

The EPiServer platform consists of the EPiServer framework with a core user interface, CMS and Commerce for content management and e-commerce, and other modules supporting marketing automation and social interaction features. A broad selection of ready-to-use add-ons is available from the EPiServer Add-on Store to extend the functionality of a solution.


  • The data layer provides the information, which can originate from the database, from one or more content providers as well external data sources integrated with EPiServer.
  • The creation layer is where content, for instance pages and blocks or e-commerce content such as products and orders, is managed. Content can be personalized, and can also be part of an approval workflow with authorization applied.
  • The delivery layer holds the presentation parts including support for responsive design and templates based on both WebForms and MVC, as well as support for building advanced search and filtering features.
  • The optimization layer provides various options for measuring, analyzing and optimizing the performance of website content, for instance conversion rates for a campaign landing page.

The platform offers shared features such as global system access and search through the OnlineCenter, the Add-on Store for easy-access to modules and upgrades, and the EPiServer Find search module for the creation of advanced search based site navigations.
