Grid computing is the collection of heterogeneous computing resources dispersed geographically to reach a common goal. Grid is composed of many networked loosely coupled systems acting together to perform large tasks.
Grid computing is a computing model which involves several computers to a single problem at the same time.
A Grid computer is the multiple numbers of same computers clustered together.
It allows flexible resource sharing among geographically distributed computing resources in multiple domains to solve a single task.
It is basically used for grid applications rich in graphics and multimedia.
Grid computing is a processor architecture that combines computer resources from various domains to reach a main objective.
In this computing model, the computers on the network can work on a task together, thus functioning as a supercomputer.
A data grid is an architecture or set of services that gives individual/group of users the ability to access, modify and transfer extremely large amount of geographically distributed data for research purposes.
It handles large distributed data sets used for data management and controlled user sharing.
It creates a virtual environment for dispersed and organized research.
Computers are spread but connected in the form of a network.
Less chances of failure of whole system.
This strategy helps to develop a virtual supercomputer system within an organization.
Data grid is another system is used where data is managed under various schema.
Can solve larger, more complex problems in a shorter time.
Easier to collaborate with other organizations.
Make better use of existing hardware
Enable recovery and failure
Ability to run large-scale applications comprising thousands of computes, for wide range of applications.
Reduces signal latency – the delay that builds up as data are transmitted over the Internet.
Real Time Examples:
The main real-time application of the grid computing model is the Automatic Teller Machine (ATM) concept that’s being used by almost every bank to cash the customer against their corresponding ATM Cards.
GARUDA is India’s Grid Computing initiative which spans across 17 cities in the country. The IIT’s Centre for Development of Advanced Computing (C-DAC’s) and many other major institutes are the participant’s of this scheme which is pioneered for research purposes.
