Introduction Cloud: cloud is one of the most important icon of the computer network we use a

cloud which denoting a type of network whether is a

point to point network. Multipoint network. switching network.

Computing: Computing is usually defined as the activity of using and developing computer technology.

Cloud computing: Cloud computing is the provision of dynamically scalable and often virtualized resources as a services over the internet Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them. Cloud computing represents a major change in how we store information and run applications. Instead of hosting apps and data on an individual desktop computer, everything is hosted in the "cloud"—an assemblage of computers and servers accessed via the Internet.

                                             

Cloud computing services often provide common business application online that are accessed from a web browser, while the software and data are stored on the servers.

The term cloud is used as a metaphor for the Internet The Cloud is a term that borrows from telephony Up to the 1990s, data circuits

(including those that carried Internet traffic) were hard-wired between destinations. Subsequently, long-haul telephone companies began offering virtual private network (VPN) service for data communication.

The term cloud had already come into commercial use in the early 1990s to refer to large Asynchronous transfer network (ATM) networks. By the turn of the 21st century, the term "cloud computing" began to appear more widely.

Advantages of cloud computing Lower computer cost. Improve performance. Reduce software cost. Instance software updates. Improved document format compatibility. Unlimited storage capability. Increase data reliability. Universal document access. Latest version availability. Easier group collaboration. Device independence.

Architecture of cloud computing

Cloud architecture the systems architecture of the software systems involved in the delivery of cloud computing, comprises hardware and software designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces, usually web services.

Individual users connect to the cloud from their own personal computers or portable devices, over the Internet. To these individual users, the cloud is seen as a single application, device, or document. The hardware in the cloud (and the operating system that manages the hardware connections) is invisible.

Why cloud computing is distinct.— User centric interface On demand service provision. Qos guarantee offer. An autonomous system. Scalability and flexibility

In 2008 IEEE conference are organized on web services held in Beijing include a panel

“Cloud computing and it as a services”.

To illustrate the definition to form a three layer architecture. (saas,paas, iaas).

Function aspect –Hardware as services,Data as services. Enabling technology behind Virtualization technology. Web services and SOA enable services. Some strategies- Microsoft-software plus services IBM-transform through customer implementation. Cisco involving interoperability.

Review and suggestion

Cloud computing still has to exist on physical servers .

Problem for users: It does leave responsibility of data storage and control in the hands of

the provider. Cloud computing has been criticized for limiting the freedom of users and making them dependent on the cloud computing provider

Solution: The majority of cloud computing infrastructure, as of 2009, consists of

reliable services delivered through data centers and built on servers with different levels of virtualization technologies. The services are accessible anywhere that provides access to networking infrastructure.

Changing the way IT resources are consumed

In coordination with large technology partners, standards bodies and cloud services providers, VMware’s leading technology platform, VMware vSphere, enables you to transform your datacenter into an internal cloud – a pool of virtualized resources within a datacenter – and seamlessly leverage external cloud providers within the private cloud.

Cloud computing represents a major change in how we store information and run applications. Instead of hosting apps and data on an individual desktop computer, everything is hosted in the "cloud"—an assemblage of computers and servers accessed via the Internet. Cloud computing lets you access all your applications and documents from anywhere in the world, freeing you from the confines of the desktop and facilitating wholesale group collaboration.

Conclusion

Hence it provide a new kind of computing platform. Its is a heavy deal over distributed and utility

computing. Cloud computing provide enormous impact over

internet . It gives us a new application programming model

technology.  Thus cloud computing provide a super-computing

power .This cloud of computers extends beyond a single company or enterprise. The applications and data served by the cloud are available to broad group of users, cross-enterprise and cross-platform.
