Cloud computing is a metaphor used for internet. It provides on-demand access to virtualized IT resources that can be shared by others or subscribed by you. It provides an easy way to provide configurable resources by taking it from a shared pool. The pool consists of networks, servers, storage, applications and services. 4/28/2018 Cloud Compuuting Services ModelsThe services models of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software-as-a-Service (SaaS). Cloud computing also is divided into five layers including clients, applications, platform, infrastructure and servers.

Grids require many computers, typically in the thousands, and commonly use servers, desktops, and laptops.
