What Is Cloud Computing ?

CLOUD COMPUTING :

"The use of a network of remote servers hosted on the Internet to save, manage, and process data, rather than a local server or a personal computer"

Cloud computing is saving the data and program over the internet in spite of Hard Drive Disk (HDD). Saving data through this way is called local storage. Every one want to get data very fast and in easy way as well as in proper form.

ORIGEN OF CLOUD COMPUTING:

Cloud computing is started since 1960 as the name of RJE (Remote Job Entry). In which we deal a large number of members of higher association like (IBM, DEC). In 1970 its platform use as a multi task like CTSS Unix port.

In1990, Telecommunication Company offered VPN (Virtual Private Network). They actually connect all the network with it to run more effetely. It expand the boundary of its infrastructure to increase its efficiency. It experiment with algorithm optimize the platform and CPUS to increase the efficiency for users.

ADVANTAGES:

Following are the advantages of cloud computing:

AGILITY:

It improve the efficiency of an organization and help to maintain the record easily and increase the flexibility of the users.

COST:

 It is very cheap in price. Its provider claim the cost reduction for the public deliver the model converts capital expenditure to operating expenditure.

DEVICE AND LOCATION INDEPENDENCE:

It enable the user to use browsing for their location and told what device use. It help to store the data on internet.

CENTRALIZATION:

It centralize the user to show the each data in all around the world and help to use it according to their requirements.

PEAK LOAD CAPECITY:

As we use it on internet so we have a lot of space to save our data on it.

EFFICENCY:

It wholly utilize the system on which it is use and make it more efficient.

PERFORMANCE:

Its performance maintain by IT experts. They provide the service and using it as the web .interface

PRIDUCTIVITY:

It increase multiple data user work on it rather than save in E-mail. It save more time and show more information.

RELIABLITY:

It is more reliable for the use of multiple sites to design and recover the data.

ELASTICITY:

It is made for receive self or according to the customer requirements it scale up while user need to increase or decrease the data due to resources.

DISADVANTAGE:

According to Bruce, it customize the option for use it. It is very cheap that everyone miss use it. 

DOWNTIME:

We are full based on our internet and can’t use it without internet this cause of expense for a single user.

SEURITY AND PRIVACY:

In it there is a leakage of risk to relief our important and personal issue by hacking.

LIMITED CONTROL:

It contain limited control according to their qualification. It can’t use to utilize the all option of it.

COST:

Its hardware cost is too expensive that rare people afford it also the expense of internet and manage of its hardware.
