Cloud computing is a general term for the delivery of hosted services over the Internet. Cloud computing enables companies to consume compute resources as a utility — just like electricity — rather than having to build and maintain computing infrastructures in-house.
Cloud computing promises several attractive benefits for businesses and end users. Three of the main benefits of cloud computing include:
- Self-service provisioning: End users can spin up computing resources for almost any type of workload on-demand.
- Elasticity: Companies can scale up as computing needs increase and then scale down again as demands decrease.
- Pay per use: Computing resources are measured at a granular level, allowing users to pay only for the resources and workloads they use.
Cloud computing services can be private, public or hybrid.
