Anything that includes offering hosted services via the internet is referred to as cloud computing. Infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service are the three primary kinds of these services (SaaS).

It is possible to have a private or public cloud. For example, anyone on the internet can buy services from a public cloud. A private cloud is a closed network or data centre that provides hosted services to a small group of people with specific access and permissions. The purpose of cloud computing, whether private or public, is to give quick, scalable access to computer resources and IT services.
