What actually is cloud computing?
In cloud computing, there are generally three so-called cloud service levels (CSE) that build on one another: Infrastructure as a Service
The basic level of cloud computing is IaaS, because this is where hardware resources are made available in virtualized form. Whether storage space, processors or network - all computing instances can be added and removed again in any amount. This is why we sometimes speak of a virtual data center.
With IaaS, the cost advantages of cloud computing... (IaaS

PaaS is the link between IaaS and SaaS and only enables the other two levels to interact. This is because the development and runtime environments for software are provided on the platform level, based on IaaS resources such as operating systems.
