What is Cloud Computing?
A definition for cloud computing can be given as an emerging computer paradigm where data and services reside in massively scalable data centers in the cloud and can be accessed from any connected devices over the internet. Cloud computing is a way of providing various services on virtual machines allocated on top of a large physical machine pool which resides in the cloud. Cloud computing comes into focus only when we think about what IT has always wanted a way to increase capacity or add different capabilities to the current setting on the fly without investing in new infrastructure, training new But cloud computing offers a better solution We have lots of compute power and storage capabilities residing in the distributed environment of the cloud. What cloud computing does is to harness the capabilities of these resources and make available these resources as a single entity which can be changed to meet the current needs of the user. The basis of cloud computing is to create a set of virtual servers on the available vast resource pool and give it to the clients. Any web enabled device can be used to access the resources through the virtual servers. Based on the computing needs of the client, the infrastructure allotted to the client can be scaled up or down. From a business point of view, cloud computing is a method to address the Scalability and availability concerns for large scale applications which involves lesser Overhead. Since the resource allocated to the client can be varied based on the needs of the client and can be done without any fuss, the overhead is very low.
One of the key concepts of cloud computing is that processing of 1000 times The data need not be 1000 times harder. As and when the amount of data increases, the Cloud computing services can be used to manage the load effectively and make the Processing tasks easier. In the era of enterprise servers and personal computers, Hardware was the commodity as the main criteria for the processing capabilities depended on the hardware configuration of the server. But with the advent of cloud Computing, the commodity has changed to cycles and bytes – i.e. in cloud computing Services, the users are charged based on the number of cycles of execution performed Or the number of bytes transferred. The hardware or the machines on which the Applications run are hidden from the user. The amount of hardware needed for Computing is taken care of by the management and the client is charged based on how the application uses these resources.
The Essay on Cloud computing Service
The “cloud” refers to the Internet; it is usually hosted on more then one server in multiple locations, normally neither the public nor the businesses know where the information is located.

They are using this service to store their software, conduct, documents, other personal and ...
Definition
A pool of abstracted highly scalable and manage computer infrastructure capable of hosting end customer applications and billed by consumption.-Forrester.
Clod computing refers to both applications delivered as service over the internet the hard ware system software in the data center that provide that service.-Berkely.
Cloud Computing is associated with a new paradigm for the provision of computing infrastructure. This paradigm shifts the location of this infrastructure to the network to reduce the costs associated with the management of hardware and software resources. The Cloud is drawing the attention from the Information and Communication Technology (ICT) community.
Types of Cloud computing:
1. Software as s service (SAAS):
Software package such as CRM or CAD/CAM can be accessed under cloud computing scheme. Here a customer upon registration is allowed to use software accessible through net and use it for his or his business process. The related data and work may be stored on local machines or with the service providers. SAAS services may be available on rental basis or on per use basis.
2. Platform as a Service (PAAS):
Cloud vendors are companies that offer cloud computing services and products. One of the services that they provide is called PAAS. Under this a computing platform such as operating system is provided to a customer or end user on a monthly rental basis. Some of the major cloud computing vendor is Amazon, Microsoft, and Google etc

However, in 2009, the university changed its name to Edinburgh Napier University. To enhance high ...
3. Infrastructure as a service (IAAS):
The cloud computing vendors offer infrastructure as a service. One may avail hardware services such as processors, memory, networks etc on agreed basis for specific duration and price.
Need for Cloud Computing in Digital Libraries
Digital library, as a most important academic and scientific research base, charges for providing information services for its users. In the past, most libraries insisted that their service is based on their own library resources. So librarians scarcely considered users’ demands. But today, digital libraries have changed this viewpoint. And librarians usually need to collect as more information as they can accord users’ requirements. Then they will analyze the information and sort out them. Finally, they will provide them for users in some certain technical methods. However, services in digital libraries will increasingly focus on users’ demanding in future. And the ultimate goal of digital library is to offer appropriate, comprehensive and multi-level services for its users. With the introduction of Cloud Computing to digital library, services of libraries will have a new leap in the near future. Services provided by digital libraries will become more user-centric, more professional and more effective, etc. And we all believe that digital libraries will create more knowledge benefits for our country with the help of Cloud Computing.
Libraries and the clouds computing.
Libraries are also not left blank with the emerging i.e. cloud computing. Many enterprises are implementing cloud computing as a new technology model for ICT infrastructure and services.Cloudcomputing allow libraries to avoid the locally hosting multiple server and equipment and constantly deal with the hardware failutre,software installation, upgrade and compatibility issue and this is possible because processes get simplified and libraries save time and money. ICT related headaches get reduce by the introduction of the technology. Further more it can concurrently make workflow simpler and permit the libraries to make available improved end user customer services with highly developed library find means and assist them online through a large network of collaboration librarians globally.
Example of clod computing in Library
OCLC Online computer library center is a nonprofit membership computer library service and research organization dedicated to the public purpose of furthering access to the world information and reducing the rate of rise of library cost. In a sense OCLC has been as a cloud computing vendor. They provide cataloguing tools over the internet and allow member institution to draw on their centralized data store. These centralized data bases allow for the sharing of catalogue record between libraries and greatly reduce the time spent cataloguing incoming material.
