EQUIVALENCE DATA GENERATION TECHNIQUE IN CASE OF DATA LOSS DUE TO FAULT OCCURRENCE IN VIRTUAL MACHINES USED IN CLOUD COMPUTING

Cloud computing is a computing like a blessed child in the field of computer. It is able to provide the solution of any problem in computers. As the data and user requirement increased two new problem came into existence, one is to store this huge amount of data and another is how to fulfil all the requirements of an individual user. As we know, computers have limitations in both the aspects, in storage as well as in the individual requirements . Ahead of this, user wants to fulfil their requirements round the clock and upto endless time. Both of these problems are solved by the cloud computing. Cloud gives unlimited space and side by side no requirement of new software or application installation on their own machine. That's why cloud is said to be the solution of every problem in the field of computer. But if any fault occurs, the whole architecture of cloud gets crippled.. To solve this problem many fault tolerant techniques are being proposed by the researchers in the field of cloud computing. Many of them are very useful. In the same sequence, we have proposed a new fault tolerant technique named as equivalence data generation technique to regenerate the lost or crashed data of any virtual machine which is being used by cloud architecture. We analysed this technique on four virtual machine architecture and successfully recovered the data of the lost virtual machine
