Cloud Computing The only thing new about Cloud Computing is the term. The concept has been around since the days of the mainframe computer. This is where the data processing happens somewhere separate from the data consumption. What is cloud computing? In one of the more bare-bones definition, it is the ability to process information on someone else’s device. For a more comprehensive definition, we go to the NIST definition. The National Institute of Standards and Technology (NIST) published its final definition of Cloud Computing in September 2011: “ Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. ” The NIST cloud computing definition and guideline was crafted, with public input, for use by U.S. Federal agencies.
