Distributed computing paradigm in which all the

resources of any number of computers are subsumed

to be treated as a Single irtual Supercomputer"

,eatures

Distributed systems must be scalable!

transparent and fault"tolerant"


20/26

Scalabilit# refers to the variability of the size of a

distributed system.

%ransparenc# refers to the invisibility of the use ofmultiple processors and remote access.

&ault %olerance if a system component breaks another

component must be able to replace.
