Our future in computing is moving into a whole new direction called Cloud Computing. Many questions and issues have arisen from this new adventure in computing. For us to understand cloud computing we must first learn what it is. Once we have established that knowledge we can then venture out to the advantages and disadvantages, types of models, and finally services in cloud environments. We will see the correlation of information that leads into how cloud computing affects us today or in our near future.
Cloud Computing and The Future
What is cloud computing? Cloud computing is described as “dumb” terminals (Bowles, M.D. 2013, Chapter 9.4). In other words, it is a way of renting computers, storage and network by the hour from companies that have these resources already established in their data center. One of the companies that are utilizing this technique is Amazon.com and many other organizations are modeling their clouds after them. It works in a similar way as electricity, when you turn your lights on you are getting charged for the electricity that you are utilizing and when you shut the power off you are not being charged. Many companies charge you the same way as the utility company, you are only paying for the applications that you are utilizing. In a nutshell, you are using programs from many different servers. Examples of cloud computing are: iTunes, documents, Apps, calendar, backup data, and synchronization.
Types of Models
Cloud models are the physical arrangement of the infrastructure and the services the end user will receive. Here are a few types of models:
Private Cloud one has exclusive use of an isolated cloud.
Public Cloud th...

- Delivering computer solutions has changed radically over the past thirty years from centralised mainframe computing to distributed client-server solutions. The consumption of Information Technology and Services (IT&S) has been accelerated by advances in network performance and facilities, consumerisation, and most notably through the adoption of Internet services. Business applications have also gone through a similar change from bespoke in-house mainframe systems to packaged products, and more recently, to distributed application frameworks (as seen on the iPhone)....

- Cloud computing security or cloud security is a growing sub-domain of network security, computer security and more broadly information security. It refers to a set politics, technologies and controls deployed to protect the data, applications and the associated infrastructure of cloud computing. Cloud computing importance is increasing and gaining scientific attention and industrial communities. Cloud computing is one among the top 10 most important technologies and with a better prospect in successful companies and organizations.... [tags: cloud computing, cloud security, private cloud]

- Cloud Computing 1. Cloud Computing Defined Cloud computing is defined to be the use of computer programs and applications, to access information, storage, that is not stored locally on a computer’s hard drive, but rather over the Internet. There are five defining characteristics to cloud computing. Cloud computing allows users to have almost no interaction with the service provider. For example, when we use Google Drive, a web application similar to Microsoft Office, we can do so without ever having to contact the service provider, Google....

- ... SECURITY ISSUES AND ITS CONTROL Companies use the Cloud in a variety of different service models like SaaS, PaaS, etc. and various deployment models like Private, Public and many more.There are two more deployment models I now remember is hybrid and community. So there are a number of security issues but these issues fall into two broad categories: 1. Infrastructure-as-a-service: The provider must ensure that their infrastructure is secure and that their client’s data and applications are protected....

- New technologies raise new ethical challenges besides new technical problems. Cloud computing is the recent technology in IT that moves the data away from portable storage devices to large data centers called cloud. It basically means that every application given as services over the Internet to the user. In the view of User it is accessing his/her files, programs and other services through Internet which are hosted by other service providers. One more aspect of cloud computing is the cost effectiveness of this technology which attracted enterprises to use this technology to consume their IT services in a cost effective way....

- Our research group has to agree that implementation of cloud computing to PCB companies can be done within the next few years because the IT industry being used by PCB companies will drastically change as the research group knows. Most or some employees may not fully understand the concepts or even grasp the basics of cloud computing in this present era but it takes time for them to learn. Personnel of PCB companies especially upper managers would expect good results and benefits both financial and technical from cloud computing in this fast moving years run by society depending on tons of IT platforms....

- 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.... [tags: Information Technology ]
