Cloud Computing is a platform for delivering computing services over the Internet.   These services are broadly defined but are also typically referred to as Infrastructure-as-a-Service (IaaS) or Software-as-a-Service (SaaS).  Typically, cloud computing customers do not own the physical infrastructure (servers, network equipment, etc), instead avoiding CAPEX and instead only pay for usage to a cloud hosting provider (like Amazon,, Google, etc).  In addition to saving on CAPEX, other features include:

  • The ability to rapidly and cost-effectively provision resources
  • Users can access systems  regardless of their location or device, the typically interface is a web browser
  • Larger providers can host multiple redundant sites, which is suitable for business continuity and disaster recovery
  • Better security since a majority of user information and data resides in a central data center, not on a user’s laptop
  • In theory, sharing of resources and costs across a large pool of users should invoke better utilization and be better for the environment over time

A cloud can be private or public, a public cloud is available to anyone on the Internet (usually per fee) and a private cloud is a proprietary network for use within a company or organization.
