What is the difference between grid and cloud computing?
grid and cloud computing may seem similar, but each of them is built and works in a different way. Both systems use multitasking capabilities and spread work aloud to other systems, but cloud computing actually takes place via the Internet rather than over several computers on the network. Cloud computing is therefore independent of location because one does not have to know where the computer that performs tasks is actually placed. On the other hand, the grid computer technology takes place in clusters of physical systems at a specific location that some call cluster computing. In addition, each system differs in cost and security, with cloud computing usually costing more and requires additional safety measures.
Although grid and cloud computing take advantage of multiple systems to perform task, cloud computing can act on request when multiple resources are needed. For example, the calculation of the grid is based on systems that are connected to the infrastructure and adding additional sizes require addition moree systems. With cloud computing, multiple resources can be requested over the Internet so that companies can add or remove resources based on business needs. Grid and Cloud Computing allow multitasking and allow users to perform as many tasks as needed.
Another difference between grid and cloud computing deals with availability. Cloud computing passes through the network, so the data fees may be costly. In addition, network fees could become unpredictable if the amount of resources required increases.
Grid Computing does not experience this problem because systems do not have to rely on Internet connection to share resources. In addition, it should be considered that cloud service providers often have variable rates that rely on the amount of resources used. If the company requires heavy processing, fees for internet and cloud services can significantly increaseIT. In this case, the company could find that the grid calculation is less cost alternative.
The very important difference between grid and cloud computing includes security problems. Cloud Computing uses resources and stored network data, so the company can have big problems if the provider has a failure. If the company uses cloud computing for selling customers, it can lose money if customers are unable to reach the system to place orders. The same problem arises if the company provides a specific service over the cloud and the service is interrupted for some reason.
Finally, the company may face problems if the cloud service provider is not interested in data regularly. Companies using computer technology can back up data on the server on the network. However, businesses that use Cloud Computing must take further steps to secure and back up important data.
