The underlying details of how it is achieved are hidden from the user. The data and the services provided reside in massively scalable data centers and can be ubiquitously accessed from any connected device all over the world. Cloud computing is the style of computing where massively scaled IT related capabilities are provided as a service across the internet to multiple external customers and are billed by consumption.

Many cloud computing providers have popped up and there is a considerable growth in the usage of this service. Amazon is the pioneer in this field.

Smaller companies like SmugMug, which is an online photo hosting site, has used cloud services for the storing all the data and doing some of its services. Cloud Computing is finding use in various areas like web hosting, parallel batch processing, graphics rendering, financial modeling, web crawling, genomics analysis, etc.

Introduction The Greek myths tell of creatures plucked from the surface of the Earth and enshrined as constellations in the night sky.

Something similar is happening today in the world of computing. In general, there is a shift in the geography of computation.

What is cloud computing exactly? While there is a lack of precise scientific definitions for many of these terms, general definitions can be given.

Cloud computing is an emerging paradigm in the computer industry where the computing is moved to a cloud of computers. It has become one of the buzz words of the industry. It includes everything that sits in the bottom layer, i. Cloud computing ties together all these entities and delivers them as a single integrated entity under its own sophisticated management.

It came partly from the cloud-like symbol used to represent the complexities of the networks in the schematic diagrams.

Itrepresents all the complexities of the network which may include everything from cables, routers, servers, data centers and all such other devices. Computing started off with the mainframe era. They were dependent on the computer administrators to give them permission or to fix their problems.

They had no way of staying up to the latest innovations. The personal computer was a rebellion against the tyranny of centralized computing operations. There was a kind of freedom in the use of personal computers.

But this was later replaced by server architectures with enterprise servers and others showing up in the industry. This made sure that the computing was done and it did not eat up any of the resources that one had with him.

All the computing was performed at servers. Internet grew in the lap of these servers. With cloud computing we have come a full circle. We come back to the centralized computing infrastructure. But this time it is something which can easily be accessed via the internet and something over which we have all the control. Cloud computing- The Concept Cloud computing is Internet "cloud" based development and use of computer technology "computing". It is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.

Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. The concept incorporates infrastructure as a service IaaS , platform as a service PaaS and software as a service SaaS as well as Web 2.

Examples of SaaS vendors include Salesforce. The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals. Cloud computing is often confused with grid computing "a form of distributed computing whereby a 'super and virtual computer' is composed of a cluster of networked, loosely-coupled computers, acting in concert to perform very large tasks" , utility computing the "packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility such as electricity" and autonomic computing "computer systems capable of self-management".

Indeed many cloud computing deployments as of depend on grids, have autonomic characteristics and bill like utilities — but cloud computing can be seen as a natural next step from the grid-utility model. Some successful cloud architectures have little or no centralized infrastructure or billing systems whatsoever, including peer-to-peer networks like Bit Torrent and Skype and volunteer computing like 2.

The majority of cloud computing infrastructure as of consists of reliable services delivered through data centers and built on servers with different levels of virtualization technologies.

The services are accessible anywhere that has access to networking infrastructure. The Cloud appears as a single point of access for all the computing needs of consumers. Commercial offerings need to meet the quality of service requirements of customers and typically offer service level agreements.

Open standards are critical to the growth of cloud computing and open source software has provided the foundation for many cloud computing implementations. Many cloud-computing offerings have adopted the utility computing model, which is analogous to how traditional utilities like electricity are consumed, while others are billed on a subscription basis. Sharing "perishable and intangible" computing power among multiple tenants can improve utilization rates, as servers are not left idle, which can reduce costs significantly while increasing the speed of application development.

A side effect of this approach is that "computer capacity rises dramatically" as customers do not have to engineer for peak loads. Adoption has been enabled by "increased high-speed bandwidth" which makes it possible to receive the same response times from centralized infrastructure at other sites.

Cloud computing users can avoid capital expenditure CapEx on hardware, software and services, rather paying a provider only for what they use.

Consumption is billed on a utility e. Other benefits of this time sharing style approach are low barriers to entry, shared infrastructure and costs, low management overhead and immediate access to a broad range of applications. Users can generally terminate the contract at any time thereby avoiding return on investment risk and uncertainty and the services are often covered by service level agreements with financial penalties.

According to Nicholas Carr the strategic importance of information technology is diminishing as it becomes standardized and cheaper. He argues that the cloud computing paradigm shift is similar to the displacement of electricity generators by electricity grids early in the 20th century.

History The Cloud is a term with a long history in telephony, which has in the past decade, been adopted as a metaphor for internet based services, with a common depiction in network diagrams as a cloud outline. Cloud computing infrastructure accelerates and fosters the adoption of innovations.

Cloud computing can enable innovations. It alleviates the need of innovators to find resources to develop, test, and make their innovations available to the user community. Innovators are free to focus on the innovation rather than the logistics of finding and managing resources that enable the innovation.

Cloud computing helps leverage innovation as early as possible to deliver business value to a company and its customers.

Cloud computing infrastructure allows enterprises to achieve more efficient use of their IT hardware and software investments. Cloud computing can increase profitability by improving resource utilization. Pooling resources into large clouds drives down costs and increases utilization by delivering resources only for as long as those resources are needed.

Cloud computing allows individuals, teams, and organizations to streamline procurement processes and eliminate the need to duplicate certain computer administrative skills related to setup, configuration, and support.

Why cloud computing? They were dependent on the computer administrators to give them permission or to fix their problems. They had no way of staying up to the latest innovations. The personal computer was a rebellion against the tyranny of centralized computing operations.

According to Nicholas Carr the strategic importance of information technology is diminishing as it becomes standardized and cheaper. He argues that the cloud computing paradigm shift is similar to the displacement of electricity generators by electricity grids early in the 20th century.

History The Cloud is a term with a long history in telephony, which has in the past decade, been adopted as a metaphor for internet based services, with a common depiction in network diagrams as a cloud outline. The underlying concept dates back to when John McCarthy opined that "computation may someday be organized as a public utility"; indeed it shares characteristics with service bureaus which date back to the s. The term cloud had already come into commercial use in the early s to refer to large ATM networks.

By the turn of the 21st century, the term "cloud computing" had started to appear, although most of the focus at this time was on Software as a service SaaS. In , Salesforce. They applied many technologies of consumer web sites like Google and Yahoo!

They also provided the concept of "On demand" and "SaaS" with their real business and successful customers. The key for SaaS is being customizable by customer alone or with a small amount of help. Flexibility and speed for application development have been drastically welcomed and accepted by business users.

IBM extended these concepts in , as detailed in the Autonomic Computing Manifesto -- which described advanced automation techniques such as self- monitoring, self-healing, self-configuring, and self-optimizing in the 12 Cloud Computing Technology management of complex IT systems with heterogeneous storage, servers, applications, networks, security mechanisms, and other system elements that can be virtualized across an enterprise.

It was a hot topic by mid and numerous cloud computing events had been scheduled. In August , Gartner Research observed that "organizations are switching from company-owned hardware and software assets to per-use service-based models" and that the "projected shift to cloud computing will result in dramatic growth in IT products in some areas and in significant reductions in other areas.

One simple question. This is a question of relevance because the amount of data that an application handles is increasing day by day and so is the CPU power that one can harness. There are many answers to this question.

With this much CPU power, we could scale our businesses to times more users. Right now we are gathering statistics about every user using an application.

With such CPU power at hand, we could monitor every single user click and every user interaction such that we can gather all the statistics about the user. We could improve the recommendation systems of users. We could model better price plan choices.Cloud computing intends to make the Internet the ultimate home of all computing resources- storage, computations, applications and allow end user toavailable them in quantities of her choice, location of their preferences, for duration of their liking.

Augmenting a traditional private cloud with the resources of a public cloud can be used to manage any unexpected surges in workload. In case of failure of the application, there is always a hot backup of the application ready to take over without disruption. The hard drive access speed becomes a limiting factor. This engine will take care of the creation of multiple copies and also the preservation of integrity of the data that is stored in the infrastructure.

The workload also demands two important tasks for two completely different people.
