Cloud Computing Essay

Cloud computing is one of the fastest growing segment of Information technology today. In simple words cloud computing means storing and accessing data and programs over the internet instead on the computer's hard drive which can be accessed from any part of the world if the individual are connected to the internet or a network connection is available 24/7. A simple example of cloud computing is g-mail. With the connection of internet through any medium we can send and receive emails.

Cloud computing is the practice of using remote storage for applications and data. The idea itself is not a new one; it has been in use for many years albeit under different names. In the earliest days of the computer age machines had to be physically large to contain the hardware required to do their jobs. It was impractical and prohibitively expensive to provide one of these mainframes for individual users; not to mention for what they were used for, unnecessary. Instead, one central computer was wired to several terminals that users could interface with. Typically, only large organizations such as, major corporations or government agencies could afford one of these machines or had need of one. This was the birth of cloud computing. Until the early 1980s this system was typical for any organization requiring large amounts of processing power. It was considered unnecessary and difficult to put the nuts and bolts of applications onto users’ desktop machines. Rather, by keeping applications in a central location, they could be managed and updated more easily and large amounts of storage space and processing power were not needed on desktop machines. Indeed, before this time there were no desktop machines mass produced that could achieve this level of power. This was about to change.

Cloud computing is the use of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

Whether you are thinking about embracing a portion of cloud computing for your IT needs or you are thinking about using it exclusively for all of the IT aspects of your business, you should first take a look at how much your company can benefit from cloud computing. The following is an overview.

Cloud computing is defined by the Investopedia online dictionary as a model for delivering data and software stored in servers that is retrieved from the internet through web-based tools and applications, rather than a direct connection to a server. When you get down to the very basics cloud computing and the traditional client/server have similar structure and functions. However, instead of purchasing and maintaining large and costly in-house servers the

1.) Cloud computing has become a new trend in the technology world. It is the upcoming stage for the Internet where every computing need can be accessed through a web browser at anytime, anywhere. It is also very economically appealing because the cost is so cheap. Cloud services have the potential to reduce information technology (IT) costs, increase operating efficiencies and create new types of business opportunities. So, what would happen to Microsoft if they do not build on a cloud computing business? First of all they would fall behind in technology trends. The business is said to emerge with rapid growth in the years ahead. Most other companies are heavily

Cloud technologies revolve heavily around virtual machines that reside on physical servers (Talbot, 2009). One physical server could be the home of a slew of virtual machines; should an attacker interrupt the normal operations of a physical server it could result in the inoperability of the virtual machines also. One of the techniques can be used is an attacker implanting a virtual machine on a physical server (Talbot, 2009). Once the

Allocation of resources-They are grouped to serve a large number of simultaneous users. Computing resources are joint together to serve numerous

The topic of cloud computing has received great research attention, due to the revolutionary power of the cloud. Researchers have extensively explores thee protocols and dynamics of the cloud, including the challenges that face it. At the same time, researchers have explored portability and interoperability as challenges that inhibit the use of the cloud, by restricting the users to a single service provider. On that note, the researchers have focused on the benefits that are to be expected in the event that the cloud becomes more portable and interoperable. However, little research literature exists in the scope of the benefits and demerits of portability and interoperability in the cloud. To this end, the current study exists to fill that gap. Nonetheless, the review of literature considers the existing literature that is relevant to the challenges facing cloud computing, as well as the solutions that existing in the scope of cloud portability and interoperability. The review of literature provides a background knowledge and review of the research topics, including what portability and interoperability are, as well as the associated challenges and benefits.

This project is going to discuss about the Cloud Computing and its application in business. To briefly describe what cloud

The property of a system to handle growing amounts of work and its ability to readily get enlarged is called Scalability. A system whose performance increases by adding required hardware in proportional to the capacity load added is called a Scalable system. Traditional operating systems are not scalable. But scalability plays an important role while designing cloud based operating systems.

for the political part there is thing that IT associations doesn't consider while contemplating the move to cloud computing. There are obviously a specialized issues that should be settled when any associations truly consider making the move to cloud computing they will locate that inward political issues will ascend to the highest priority on the rundown of boundaries to appropriation. loads of utilizations proprietor will oppose surrendering control of their applications and the committed servers because of a few reasons which is worries about application execution as well as capacity to convey and control any updates to those applications. Strategy issues, for example, data protection,

The flexibility of cloud computing is a function of the allocation of resources on demand. This facilitates the use of the system 's cumulative resources, negating the need to assign specific hardware to a task. Before cloud computing, websites and server-based applications were executed on a specific system. With the advent of cloud computing, resources are used as an aggregated virtual computer. This amalgamated configuration provides an environment where applications execute independently without regard for any particular configuration.

Cloud Computing is the use of common software, functionality or business applications from a remote server that is accessed via the Internet. Basically, the Internet is the "cloud" of applications and services that are available for access by subscribers utilizing a modem from their computer. With Cloud Computing, one simply logs into desired computer applications - such as sales force or office automation programs, web services, data storage services, spam filtering, or even blog sites. Generally, access to such programs is by monthly or annual paid subscription. Through Cloud Computing, businesses may prevent financial waste, better track
