Cloud Computing 101
Cloud computing, in its most basic form, is “using computer services [such as computer and data storage, management and processing] that are delivered over a network” (Kim & Solomon, 2013, p. 189). For example, an organization may require a great deal of storage for their data but may not want to purchase the servers, the physical space for the servers, or the personnel to manage the infrastructure. Instead, they take advantage of the many cloud computing options and outsource their needs, hiring someone to do everything off-site usually with the goal of reducing their overall cost of ownership. As defined by the National Institute of Standards and Technology (NIST), cloud computing has five essential characteristics, three service models, and four deployment models (Mell & Grance, 2011) which will be covered, briefly, in the next few sections.
Essential Characteristics With the ability to be more flexible, require less overhead, and access the data anywhere in the world (usually), cloud computing is becoming an increasingly popular option, offering a wide array of services and solutions. These services and solutions, although unique, generally have the same essential characteristics. The five essential characteristics, as defined by NIST, are:
• “On-demand self-service” (Mell & Grance, 2011, p. 2) or the ability to rapidly modify and adjust their needs independent of service provider interaction
• “Broad network access” (Mell & Grance, 2011, p. 2) or…
