Understanding the Architecture
The database servers store the user, application, and configuration data. The user data contains
information such as documents that are saved in document libraries. The application data is specific to each
feature running in the SharePoint farm, which is described shortly. For example, it may contain some of the
search indexing information. The configuration data contains the administrative settings at the farm and
These components can be deployed on the same machine, or scaled out to multiple machines. Chapter 6
discusses the various topologies that are supported.
The SharePoint Hierarchy
A SharePoint farm is a collection of one or more machines that have the roles of WFE, application server,
and database server, and are managed by the same central administrator.
A SharePoint farm is composed of one or more web applications . Each web application, also known as
Windows SharePoint Services (WSS) Virtual Server (vServer), is a separate Internet Information Server
(IIS) application pool and has a different IIS port. Most farms will have one web application, but in large
enterprises, the central Information Technology (IT) manages several web applications in the same farm.
Each web application has a separate content database for storing its user data.
A web application has one or more WSS site collections. The site collection is the top-level container for
sites and subsites .
Each of the WFE machines supports all the web applications and all their site collections and sites.
