Cloud refers to the large variety of most wanted services to companies and customers online. The advantage of cloud services is that these applications and resources are affordable, thus providing simplified design without any internal infrastructure or hardware installations.
A dedicated public internet provides complete services on computing, storage, networking, and other elements that we call IaaS. Users can own and manage the OS, applications & data running on the infrastructure and pay, as per the usage.
PaaS (Platforms-as-a-Service) provides a restful platform, on which we can run the applications and IT infrastructures needed to run.
