What is CLOUD COMPUTING?


7/33

Contd.7

Cloud Computing is a general term used to describe a new clnetwork based computing that takes place over the Internet.

Basically a step towards Utility Computing.

A collection/group of integrated and networked hardware,

software and Internet infrastructure .

Using the Internet for communication and transport provides

hardware, software and networking services to clients.

These platforms hide the complexity and details of tunderlying infrastructure from users and applications

providing very simple graphical interface or API.

Grid computing is a networkthat is not in the same place

but distributed resources such

as computers, peripherals,

switches, instruments, anddata.

How Grid Works?21

To grid computing, though its resources have beenlooks like a huge resource pool from outside.

But to the user who has submitted a special task,

know which node will complete his job.

What he need do is to submit his job to the grid

to a special style, and then what he will do next

for the result.

Contd

And the grid job schedule system will look for the reis matched to job, and find idle physical node, send

until the job will be finished.

Though grid can realize parallel job processing, the prepare the algorithm himself, and send them to diff

physical nodes.

Grid Computing VS Cloud Comp

Job scheduling is the core value and

aim of grid technology, its aim is to useall kinds of resources.

It can divide a huge task into a lot of

independent and no related sub tasks,

and then let every node do the jobs.

Even any node fails and doesnt returnresult, it doesnt matter; the whole

process will not be affected.

Even one node crashes, the task it

should do will be reassigned to other

nodes

It has some advantages, such as: One can provide unlimited compute

power through any computer, and can

get a great deal of information.

This environment can help enterprise

complete tasks that are very hard

before, and use their systemsefficiently, to meet the users

requirement and decrease the

management cost.
