Grid computing is making big contributions to scientific research, helping scientists around the world to analyze and store massive amounts of data.
SETI (Search for Extraterrestrial Intelligence) @Home project
SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.
Grid computing is a form of distributed computing whereby resources of many computers in a network is used at the same time, to solve a single problem. What distinguishes grid computing from conventional cluster computing systems is that grids tend to be more loosely coupled, heterogeneous, and geographically dispersed.
Cloud computing is how data is accessed using remote servers via Internet (known as “the cloud”). Cloud computing relies on sharing hardware and software resources over a network rather than on local servers or personal devices. This network of servers and connections is collectively known as the cloud. Google Docs is an example of Cloud computing. Cloud services can be used to provide high-performance computing, as needed.
