Grid computing enables the virtualization of distributed computing and data resources such as processing, network bandwidth and storage capacity to create a single system image, granting users and applications seamless access to vast IT capabilities. Just as an Internet user views a unified instance of content via the Web, a grid user essentially sees a single, large virtual computer.

At its core, Grid computing is based on an open set of standards and protocols the Open Grid Services Architecture (OGSA) that enable communication across heterogeneous, geographically dispersed environments. With Grid computing, organizations can optimize computing and data resources, pool them for large capacity workloads, share them across networks and enable collaboration.

Main Standardization areas are as follows:
  • Grid Middleware
  • Grid Data management
  • Grid Security
  • Grid User environment
  • OGSA

Discussion on grids in the telecoms community, involves more than just how to provide bigger pipes, there are a number of other areas of interest. At a simple level, telecommunication service providers could use grids internally, for billing and simulations for example. They could also offer grid managed services, or act as service brokers.
