6.1.2.1 Cloud versus Grid
The evolution of distributed systems has shifted from infrastructure-
oriented architecture to service-oriented architecture. Figure 6.2 shows this
change in perspective in detail. With the advent of networking technologies,
the style of computing has also changed. The collaboration of services de-
ployed across different computing networks and the capability of using these
services without platform or infrastructure limitations have shifted computing
to a large scale.
