Cloud Computing

Community Glossary

Cloud computing, colloquially referred to as "the cloud", is a model for sharing computer resources via the internet in which users can run their own workloads using scalable, abstracted resources.

Cloud computing services typically fall into one of three categories:

  • Infrastructure as a Service (IaaS) - in which infrastructure is provided as a product over the Internet.
  • Platform as a Service (PaaS) - Similar to IaaS but where the underlying infrastructure of each platform is abstracted.
  • Software as a Service (SaaS) - software is provided as a product over the Internet
