Scalable internet services
Fred Douglis, M. Frans Kaashoek · IEEE Internet Computing · 2001
As the Internet has grown from an experimental system to a commercial reality, the number of users and services has expanded exponentially. When the Internet started, an “Internet service” meant roughly one of three things: electronic mail, file transfer, or remote login. Today, “Internet service” is nearly synonymous with the World Wide Web, but the Web is not limited to simple hypertext documents — it includes rich media such as audio and video as well as personalized content in the form of Web portals.
