Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Distributed operating system is the logical aggregation of operating system software over a collection of independent, networked, communicating, and spatially disseminated computational nodes. Individual system nodes each hold a discrete software subset of the global aggregate operating system. Each node-level software subset is a composition of two distinct provisioners of services. The first is a ubiquitous minimal kernel, or microkernel, situated directly above each node's hardware. The microkernel provides only the necessary mechanisms for a node's functionality. Second is a higher-level collection of system management components, providing all necessary policies for a node's individual and collaborative activities. This collection of management components exists immediately above the microkernel, and below any user applications or APIs that might reside at higher levels.
