Cloud computing is revolutionizing every aspect of Information Technology. Many businesses and organizations rely on their own internal IT departments to operate their specific applications, databases, and programs. Cloud allows them to cut ties with in-house servers and receive their complete IT needs from an external Cloud provider. Cloud is faster and easier to use than traditional infrastructures, often making it more cost effective. Several private companies have already switched to Cloud and the federal government has ordered every agency to identify at least three “must move” services and shift them to Cloud by mid 2012. (Scharff, 2011)
When an organization decides to launch a computer based application they have to establish an infrastructure utilizing their own IT department. Initial investments go towards servers, data storage, software, and staff to design and support the system. Depending on the size and intensity of the application it could take a significant amount of time before the system is functioning properly. Once the application is operating, increased usage and growth along with hardware or software failures can hinder performance or corrupt the entire system. Cloud is refining IT as a resource that is accessible anywhere, similar to a utility. Comparable to the power grid that encompasses America, users simply plug in through an Internet connection and pay for what they use. (Scharff, 2011) Cloud providers offer IT resources that support all types of applications along with compatible hardware, software, and programing. Organizations connect to a third party Cloud provider that proposes and designs an application to meet their unique business needs. Users are provided with constant system upgrades, data storage, and unlimited support. Organizations rent or lease the IT resources they utilize, saving capital that is required for an initial start-up investment or constant system upgrades and maintenance. Much like a giant office building provides the basic resources that can be tailored to fit several different businesses specific needs, Cloud providers offer customizable IT resources to satisfy an organization’s demands. (Salesforce, 2011) Employing Cloud allows the organization to focus on its primary goals and objectives.
While Cloud has several advantages over traditional systems, there are some significant concerns. Access to the Cloud depends on an active Internet connection. A decrease in bandwidth can significantly slow operations while an internet outage can...
