Cloud Resource Virtualization

Three classes of fundamental abstractions – interpreters, memory, and communications links – are necessary to describe the operation of a computing system [312]. The physical realization of each one of these abstractions, such as processors that transform information, primary and secondary memory for storing information, and communication channels that allow different systems to communicate with one another, can vary in terms of bandwidth,1 latency,2 reliability, and other physical characteristics. Software systems such as operating systems are responsible for the management of the system resources – the physical implementations of the three abstractions.

Resource management, discussed in depth in Chapter ...
