In cloud computing, which of the following statements is true about the differences between Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) cloud computing models, as well as the differences between public, private, and hybrid cloud deployment models? IaaS, PaaS, and SaaS models all provide the same level of abstraction, with the only difference being the types of applications they support.   IaaS, PaaS, and SaaS models are all private cloud deployment models, with the only difference being the level of abstraction they provide.   IaaS, PaaS, and SaaS models provide different pricing models, with IaaS charging by usage of computing resources, PaaS charging by usage of a development platform, and SaaS charging by subscription to software applications, while public, private, and hybrid deployment models refer to different levels of scalability.   IaaS, PaaS, and SaaS models are all public cloud deployment models, with the difference being the level of control over the infrastructure.

IaaS, PaaS, and SaaS models are all private cloud deployment models, with the only difference being the level of abstraction they provide.
 
IaaS, PaaS, and SaaS models provide different pricing models, with IaaS charging by usage of computing resources, PaaS charging by usage of a development platform, and SaaS charging by subscription to software applications, while public, private, and hybrid deployment models refer to different levels of scalability.
 
IaaS, PaaS, and SaaS models are all public cloud deployment models, with the difference being the level of control over the infrastructure.
 
IaaS, PaaS, and SaaS models provide different levels of abstraction, with IaaS providing raw computing resources, PaaS providing a platform for developing and deploying applications, and SaaS providing software applications, while public, private, and hybrid deployment models refer to different levels of control over the infrastructure.
