Performance Planning for Web Servers

Paul Reeser

Web servers play an integral role in Internet commerce and telecommunications service offerings. Web servers are portals to external customers (over the Internet), and they are also an interface to internal agents (over corporate Intranets). In many modern telecommunications applications, the Web server is as a vehicle to provide a "unified desktop" interface for customer care (CC) agents. The CC agents will access a myriad of incompatible Operations Support System (OSS) applications for customer workflow processing (ordering, provisioning, billing, ticketing, etc).

Typically, these Web servers provide

This talk discusses many critical aspects of end-to-end capacity/performance planning for such Web-based architectures, and (time permitting) presents a queueing model for Web servers in distributed environments. The modeling results lead to a fast and accurate analytic approximation for the key end-user performance measures.
