Question

Which option has the maximum responsibility of Customer?

A) IaaS
B) PaaS
C) SaaS
D) Equal in all options

Answer 1

The customer has the maximum responsibility in an Infrastructure as a Service (IaaS) model, where they manage applications, data, runtime, middleware, and the operating system.

Step-by-step explanation:

The student has asked which option between Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) has the maximum responsibility for the customer. Each of these service models assigns different levels of responsibility to the service provider versus the customer. In a SaaS model, the provider is responsible for most things, including the application and data. In PaaS, the customer is responsible for the applications and data, while the host manages everything else. In IaaS, the customer has the most responsibility, managing the applications, data, runtime, middleware, and the operating system. Therefore, the correct answer is A) IaaS.

Answer 2

Customers have the maximum responsibility in an IaaS model, where they manage everything above the infrastructure level. PaaS reduces customer responsibility to managing applications and data, while SaaS minimizes customer responsibility, as the provider manages virtually all aspects except for data and user access.

Step-by-step explanation:

The question relates to the different levels of responsibility customers have depending on whether they are using Infrastructure as a Service (IaaS), Platform as a Service (PaaS), or Software as a Service (SaaS) cloud computing models. At the IaaS level, customers have the maximum responsibility, as the provider only supplies the infrastructure while the customer must manage everything from the operating system upwards. In PaaS, the provider manages the infrastructure and platforms, leaving the customer to manage applications and data. Finally, at the SaaS level, the provider manages almost everything, including applications, and the customer's responsibility is typically limited to managing their data and user access. Therefore, the correct answer to which option has the maximum responsibility for the customer is A) IaaS.
