What is the “Cloud”? What is “Cloud” computing? These are questions I get all the time. For the vast majority of people, the “Cloud” is a lofty term having to do something with computing or, let’s be honest, puffy cumulus wisps of moisture floating around in the sky. The truth is the “Cloud” is a marketing term made up to sell a service (note: the quotation marks around “Cloud” were to delineate that marketing term. From here on out, “Cloud” will be written sans quotation). That service, the Cloud, is computing and storage capacity as a service. In human terms, it is a system of delivering computing and storage needs via three types of computing services: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). Although this is true, for most people Cloud can be broken down into two categories, Public or Private.
