Hi Steve, I think we covered cloud computing in a previous thread, see below.

Out of interest, would you call Googles massive infrastructure and resources a cloud or grid?

They're both marketing buzz words so definitions may vary. In my experience, subtle differences exist.
Grid: Fixed resource pool consisting of multiple nodes for running batched (not realtime) computing tasks. Facilities generally used by single entity.
Cloud: anonymous resource pool that will scale near-real time per demand. Physical facilities are shared between multiple users. Details of infrastructure (most notable: geographical location) are hidden from end users
Cancer research is generally run on a grid. Seti@home is a hybrid. Amazon EC2 is (by definition ;-)) a cloud service.

Hi guys, Been looking up these two, 'Cloud computing' and 'Grid computing' and I'm still to figure out the real difference between them. According to Wikipedia: Cloud computing, is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet. Grid computing, is the application of several computers to a single problem at the same time – usually to a scientific or technical problem that requires a great number of computer processing cycles or access to large amounts of data. To me they both seem like one and the same, i.e. a) They both have to do with making a larger underlying system appear as a single whole. b) They both have to deal with large complex hardware and software implemetations which are often virtualised. c) They can both be implemented across large geographical locations, etc etc. So do clouds exist within a grid? Or do grids use clouds as an interface to the resources they provide? Why the two terms?
