Cloud vs. Grid Computing
It is thought that Cloud computing has evolved from Grid computing. This is because in Grid computing instances play bigger role and are referred to as separate devices which form together a distributed network and resource integration. The biggest drawback of grid computing is that there is a single point of failure if one unit on the grid degrades or becomes faulty.
On the other hand, Cloud computing tries to enhance the concept of Grid computing and avoid the single point of failure when one unit fails. Cloud computing is designed to act as one whole and its compound units to be automatically interchangeable. That is why cloud hosting offers the highest level of data security in the hosting market.
