This document discusses web server architecture and types of architectures. It begins with defining a web server as software that controls how users access hosted files and ensures delivery of website content. It then describes web server architecture as the logical design consisting of parameters like physical capacity, performance, application tiers, platform, and network connectivity. The main types of architectures are listed as multi-process, multi-threaded, single process event-driven, and asymmetric multi-process event-driven. Examples of popular web servers are also provided, including Apache, IIS, Lighttpd, and Sun Java System Web Server.

Introduction • Web server software controls how a user accesses hosted files. • It is accessed through the domain names of websites and ensures the delivery of the site's content to the requesting user. As software • A Web server is a computer that holds web server software and other files related to a website, such as HTML documents, images and JavaScript files As hardware A web server is server software, or hardware dedicated to running said software, that can satisfy World Wide Web client requests The most common use of web servers is to host Websites There are other uses such as gaming, data storage or running enterprise applications. 3

Web server architecture is the logical layout or design of a web server, based on which a web server is designed, developed and deployed. Introduction 4
- 5. Web server architecture consists of parameters including, but not limited to: Physical capacity In terms of computing power, storage and memory Performance and quality of service (latency, throughput, low memory utilization) Application tiers (type of different applications deployed on the server) Platform supported (.Net, LAMP) Operating system (Windows, Linux, Solaris) Network and/or Internet connectivity (modes of connection and the number of concurrent users it can support) 5
