Cluster, grid and cloud computing are three main technologies for computing with each having its advantages and disadvantages. They have emerged during different periods of time as per needs of the time. Cluster computing is simply connection of computers using fast speed LAN to provide computing with efficiency and guaranteed availability. Grid computing is technology used mainly for number crunching like a supercomputer. It uses distributed environment of different networks or nodes. Cloud computing is latest of them.
