The software distributes processing loads among server resources so that multiple
client requests for information can be met without delay.
Middle tier
The middle tier enables users to access intelligence data and functionality via a web
browser. This tier provides web-based interfaces for report creation and information
distribution, while passing analysis and processing requests to the SAS servers.
Clients
The client tier provides users with desktop access to intelligence data and
functionality through easy-to-use interfaces. For most information consumers,
reporting and analysis tasks can be performed with just a web browser. For more
advanced design and analysis tasks, SAS client software is installed on users'
desktops. Some support for mobile devices is also provided.
Note: The four tiers represent categories of software that perform similar types of
computing tasks and require similar types of resources. The tiers do not necessarily
represent separate computers or groups of computers.
The following diagram shows how the tiers interact, and the sections that follow
describe each tier in more detail.
