OCI has three Service Models mainly.
Infrastructure as a Service (IaaS) :(Sometimes it’s called Hardware-as-a-Service).
IaaS companies provide off-site server, storage, and networking hardware, which you rent and access over the Internet.
IaaS gives a virtual machine which we have to maintain. The difference between IaaS and having a physical server room is we don’t have to buy any physical computers and we can have servers in various parts of the world.
Platform as a Service (PaaS):sometimes called middleware.
In PaaS, the cloud service provider hosts and manages a platform (or framework) on which the customer can develop, build, test, and deploy their own custom applications.
Software as a Service (SaaS):
It refers to cloud-based software that is hosted online by a company and is available for purchase on a subscription basis and is delivered via the internet.
Point to remember:
>>IaaS is the most basic, PaaS builds on IaaS and finally SaaS is being built on top of PaaS.
>>IaaS helps build the infrastructure of a cloud-based technology. PaaS helps developers build custom apps via an API that can be delivered over the cloud. And SaaS is cloud-based software companies can sell and use.
