B) IaaS: infrastructure is a service that provides infrastructure such as hardware, such as memory and processor speed, and so on.
C) PaaS: platform is service, which provides a cloud application platform for developers.

22) how important is the platform, that is, service?

Platform service (PAAS) is a very important layer in cloud computing. It provides an application platform for the provider. It is responsible for providing the full virtualization of the infrastructure layer and making it run like a single server.

23) what is the cloud service?

Cloud services are used to build cloud applications through the Internet, using the servers in the network. It provides this convenience: no cloud applications can be installed on a computer and can be used directly. It also reduces the work of maintaining and supporting applications that use cloud service development.
