Resource Management of a Consolidated Web Server

A single web server can be managed by controlling the amount of resource that the entire web server can use. This is useful in an environment in which a web server is being consolidated with other workloads. This is the most basic form of resource management, and simply prevents other workloads from impacting the performance of the web server, and vice versa. For example, if a CGI script in the web server runs out of control with a memory leak, the entire system will not run out of swap space; only the web server will be affected.

In this example, a web server is allocated 20 shares, which means that it is guaranteed at least 20 percent of the processor resources should the database place excessive demands on the processor.

See Putting on a Web Front-end Process for an additional web server example.
