A computing environment (“the cloud”) consists of networks, servers, data storage, application, and services that can be easily managed and accessed through a networking protocol, usually the internet.
Cloud computing can be delivered on a public cloud (using the public internet), private cloud (using a private network), community cloud (using shared cloud resources), or hybrid cloud (a combination of public, private, or community clouds). The most common cloud computing service models used for ERP software are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
