Web Technology

Due to cloud computing's fundamental reliance on internetworking, Web browser universality, and the ease of Web-based service development, Web technology is generally used as both the implementation medium and the management interface for cloud services.

This section introduces the primary Web technologies and discusses their relationship to cloud services.

Resources vs. IT Resources

Artifacts accessible via the World Wide Web are referred to as resources or Web resources. This is a more generic term than IT resources. An IT resource, within the context of cloud computing, represents a physical or virtual IT-related artifact that can be software or hardware-based. A resource on the Web, however, can represent a wide range of artifacts accessible via the World Wide Web. For example, a JPG image file accessed via a Web browser is considered a resource. For examples of common IT resources, see the IT Resource section.
