Energy Efficient Offloading With Flow Control

Cloud computing will continue to grow in popularity. As more businesses look for ways to cut cost, cloud computing will eliminate the need to have the storage space, money needed to purchase and upgrade equipment and to have the technical knowledge to handle problems that arise.

What is cloud computing? Cloud Computing is storing and accessing applications and data over the Internet and not locally of your computer’s hard drive. The concept has been around and in use for years. To put it more simply, cloud computing means providing processing power to electronic devices (PCs, tablets, smartphones) via a remote infrastructure. There are some advantages and disadvantages of using cloud computing in a business environment. I will be describing three advantages and three disadvantages of using cloud computing in everyday business.

Cloud computing is a new technology that comes with both benefits and drawbacks and like any new tech it can be used to great success when paired with steps to mitigate the security issues it raises. Cloud computing has become somewhat of an ambiguous term often having different meaning for different people. An article in InfoWorld (2013) stated, ”Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any

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.

In his article “Online 24/7: ‘Life Logging’ Pioneer Clarifies the Future of Cloud Computing”, Larry Greenemeier (2011) describes the idea of cloud technology, where it stands today and where we are heading to. According to Greenemeier’s article, the idea of cloud computing is to make all the information and services available via web. It will enable access to data and apps without the need for a lot of storage or processing power on the devices themselves.

The goal of cloud computing is to apply traditional supercomputing, or high-performance computing power, normally used by military or research facilities, to perform tens of trillions of computations per second, in consumer-oriented applications such as financial portfolios, to deliver personalized information, to provide data storage or to power large, immersive computer games. When organizations contract for cloud services, such as applications, software, data storage, and processing capabilities, they can improve their efficiency and their ability to respond more quickly and reliably to their customers’ needs. At the same time, there are risks to be considered, including maintaining the security and privacy of systems and information, and assuring the wise expenditure of IT resources.

The aim of Cloud Computing is to let users to take advantages of all the technologies, without the require of professional knowledge of each of them. The goal of cloud is to reduce costs so that users can concentrate on their main business without get impeded by professional IT barriers.

In plain terms, Cloud Computing enables end users to utilize parts of bulk resources and these resources can be received quickly and easily.

The cloud computing, in comparison with personal computing, offers an extensive range of competencies. Cloud computing is defined in broader terms as “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet.”12

The overall concept of cloud computing is one which is based on a new architectural model of computer resources which means the data is stored remotely, but is provided to users as if it was stored locally. This new concept has been described as being "a style of computing where massively scalable IT-enabled capabilities are delivered 'as a service' to external customers using internet technologies" ("Will IT of the Future Have Its Feet Firmly Planted in the "Cloud"?," 2008), in a dramatic shift from traditional computing methods. Cloud computing is also able to provide services to the end user seamlessly, to serve applications from a central location, regardless of the user’s location. There are numerous services such as

Cloud computing is a technology that has come full-circle in recent years. Computer equipment used to be too expensive for an average individual to own. The original industry model was a computer mainframe with dummy terminals. This fit the technical definition of Cloud Computing in a primitive sense because all data was stored and accessed from the mainframe. With the advent of the microprocessor, MS-DOS and Windows, hardware and software prices dropped and computers became commonplace in businesses and homes. This transition led to a model with personal computers storing data locally and not being connected to each other. Then as the Internet was created and the World Wide Web was developed to explore it, Personal Computers became

Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.

The cell phones are joined with the mobile systems through base stations (e.g., base station, access point, or satellite) that establish and control the associations and practical interfaces between the systems and cell phones. Mobile clients’ requests and data (e.g., ID and area) are transmitted to the central processors that are associated with servers giving mobile system services. Here, mobile system administrators can give services to mobile clients as authentication, authorization, and bookkeeping focused around the home agents and subscribers’ information stored in databases. After that, the subscribers’ requests are conveyed to a cloud through the Internet. In the cloud, cloud controllers service these requests to furnish mobile clients with the corresponding cloud services. These services are developed with the ideas of utility processing, virtualization, and service-oriented architecture (e.g., web, application, and database servers).

Cloud computing enables companies to consume compute resources as a utility -- just like electricity -- rather than having to build and maintain computing infrastructures in-house.
