The Future of Cloud Computing
April 21, 2014
The Future of Cloud Computing – What Is It & What Does It Mean? The shift to cloud computing is a major change in the industry of computer technology. Cloud computing is a tool that allows a person to access software, server and storage resources over the Internet, in a self-service manner. Instead of having to buy, install, maintain and manage these resources on a personal computer, documents can be accessed anywhere a person has a Web connection. After reviewing the types of cloud computing, examples of cloud computing, the advantages and disadvantages of cloud computing it is easy to see that it is a trend in the world of technology that is helping to shape the future. Types of Cloud Computing
There are currently four types of cloud computing (Bowles, 2013). The first is the Global Information Cloud, which is considered to be the internet. It is accessible to anyone with a computing device with internet connectivity. The External Information Cloud is the second, and is often represented by the closed and private data within an organization, such as an extranet that a company may have. The third cloud is known as the Local Information Cloud, which the owner maintains control of and anyone that accesses this type of cloud must have membership to do so, such as a home network of computers playing a game together on separate devices. The fourth type of cloud is referred to as the Personal Information Cloud. This cloud contains all of the information that an individual has created, and can consist of photos, documents, or data created and maintained by that individual. Bhatt (2012) states that Cloud computing is broken down into three different categories; Public Cloud, Private Cloud and the Hybrid Cloud, which is a combination of public and private. He states that “The Public Cloud (external Cloud) computing resources are on-demand purveyed over the Internet via Web applications or Web browsers from an off-site third-party service provider. The Private Cloud (internal Cloud) is Cloud Computing over private networks made exclusively for one client giving full control of data, security and service quality and they can be built and managed by a company’s own organization or by a Cloud service provider. The Hybrid Cloud Computing blends various public and private Clouds and introduces complexity of distribution of application across both a private and public Cloud.” Examples of Cloud Computing
There are many tools to utilize Cloud Computing. With the constant evolution of technology in computers and smartphones, Cloud Computing will continue to evolve. Not just with the data that can be stored but the applications that can be utilized through Clouds as well. Stevenson & Hedberg (2011) point out that “The two most widely used services – Google’s Apps for Education and Microsoft’s Live@Edu – are free for education institutions with no advertising and with the ability to use the institution’s domain name as part of the service. These services offered by Google and Microsoft specifically to education institutions have garnered attention only in the last few years, even though they comprise many Web 2.0-styled service features like web-based e-mail, contacts, social bookmarks and calendars which have all been available in some form for over a decade. ” Apps for Education involves a set of web applications with full customer support, including applications such as Gmail, Docs and Spreadsheets (which are similar to Microsoft Word and Excel), Calendar, Contacts, Groups, Gtalk, Google Wave, Video and Sites. When using the Apps for Education Cloud, accounts are created by the system administrator rather than by the users themselves, enabling the educational institution to ensure that all users have access to the applications. There are many examples of Clouds available to...
