Carnegie Mellon University, MIT, Stanford University, the University of Maryland, and the University of California at Berkeley, quickly followed suit. The concept evolved with the Internet, and businesses began offering “virtual” private networks as a rentable service, eventually leading to the development of the modern cloud computing infrastructure in the 1990s. In 1970s, IBM came out with an operating system (OS) named VM. Cloud Computing can be defined as delivering computing power( CPU, RAM, Network Speeds, Storage OS software) a service over a network (usually on the internet) rather than physically having the computing resources at the customer location. In the same year, Google launched the Google Docs services. Mobile cloud computing is being harnessed by bringing into existence a new infrastructure, which is made possible by getting together mobile devices and cloud computing. Clouds are of four types: public, private, community, and hybrid. This enables a company to store and access data or programs virtually, i.e. In 2006, Amazon launched Amazon Web Services, which offers online services to other websites, or clients. It comes with huge amounts of storage, the ability to handle multiple projects, and more availability to a variety of users, simultaneously. Having said that, security is, and may always be, the primary concern of most Cloud users. The Intergalactic Computer Network, otherwise known as the Internet, is necessary for access to the Cloud. A driving factor in the evolution of cloud computing has been chief technology officers seeking to minimize risk of internal outages and mitigate the complexity of housing network and computing hardware in-house. Evolution of Cloud ComputingNick Peterson, Director of Engineering 2. It acted as a primitive Cloud with two or three people accessing it. The prohibitive costs of this mainframe devices did not make them economically feasible for organizations to buy them. Guest Operating Systems could be run on every VM, with their own memory and other infrastructure, making it possible to share these resources. JCR, or “Lick” was both a psychologist and a computer scientist, and promoted a vision called the “Intergalactic Computer Network,” in which everyone on the planet would be interconnected by way of computers, and able to access information from anywhere. This means that the consumer of cloud services reposes lot of trust on the provider of those services. Businesses could purchase the software in an on-demand, cost-effective manner, without leaving the office. Here, we come up with a new concept called Virtualization in Cloud Computing, in which we will explore its working. This infrastructure allows the cloud to execute massive tasks and store huge data, as processing of data and its storage do not take place within mobile devices, but only beyond them. The universities immediately realized computer experiments can be done faster and for less money, if IBM and Google were supporting their research. The 1990s witnessed telecom operators begin offering virtualized private network connections, whose quality of service was as good as those of point-to-point (dedicated) services at a lesser cost. There are essentially two kinds of Public Clouds. Cloud deployment models indicate how the cloud services are made available to users. To IT managers, it means to minimize cap-ex by outsourcing most of the hardware and software resources. Users can choose public, private or hybrid storage offerings, depending on security … And finally, for many business projects, it is simply faster and easier to use the Cloud. In the same year, NASA’s OpenNebula provided the first open-source software for deploying Private and Hybrid Clouds. Private Clouds offer all the advantages of a Public Cloud, but have the advantage of controlling security and privacy concerns. Mobile computing is getting a fillip as customers are wanting to use their companies' applications and websites wherever they are. The following diagram shows the graphical view of cloud computing … These are distributed systems and its peripherals, virtualization, web 2.0, service orientation, and utility computing. In 2002, Amazon introduced its web-based retail services. 2007 was also the year when Netflix launched it’s streaming video service, using the Cloud, and provided support for the practice of “binge-watching.”. Cloud security has become a fast-growing service, because of its importance to customers. Storage options. Cloud computing offers many tangible benefits, but you must be ready to deal with the challenges.

They are scalable, and the users avail only those services that they use. The Cloud gained popularity as companies gained a better understanding of its services and usefulness. Since then, cloud computing has been evolved from static clients to dynamic ones and from software to services. (What could such an unrealistic, impossible-to-pay-for, fantasy of the future look like?) This includes the protection of critical information from accidental deletion, theft, and data leakage. That was the time when the idea of provision of shared access to a single computer occurred to the companies to save costs. Google and Microsoft followed soon after.
