SAS Workspace Server
SAS Workspace Servers interact with SAS by creating a server process for each client connection. The workspace server process is owned by the client user who made the server request. Each workspace server process enables client programs to access SAS libraries, perform tasks by using the SAS language, and retrieve the results.
Pooled workspace server
SAS Pooled Workspace Servers are configured to use server-side pooling and load balancing. a configuration in which the client application maintains a collection of reusable workspace server processes is called pooled workspace server.
