The four core cloud services are:
Infrastructure as a Service (IaaS): IaaS provides access to computing resources, such as servers, storage, and networking, on demand.
Platform as a Service (PaaS): PaaS provides a platform for developing, deploying, and managing applications.
Software as a Service (SaaS): SaaS provides access to software applications over the internet.
Functions as a Service (FaaS): FaaS provides a platform for running short-running functions without having to worry about provisioning or managing servers
