SharePoint basic concepts - 2

Logical and physical architecture
Whenever you deploy a SharePoint environment, in reality, you’re deploying a logical architecture called a SharePoint farm. A SharePoint farm is a set of servers that have different roles and offer various services that together make up a server farm suitable for hosting a full SharePoint deployment. Here are the common server roles in a SharePoint farm:


  • Front-end web servers These servers publish websites, often called web applications.



  • Application servers These servers host back-end services, such as Search services, the User Profile service, Excel Services, and so forth.



  • Database servers These servers store configuration and content data for the entire SharePoint farm.

The smallest farm you can build is based on a single server; this type is often called the single server farm deployment. However, it is highly recommended that you avoid such a scenario, except for testing or development.
