A financial services company is planning its migration to Microsoft Azure to leverage cloud computing benefits. Their primary objectives include minimizing operational overhead, ensuring strict compliance with regulatory standards, and focusing on application development without the burden of managing underlying infrastructure. Given these goals, consider the following statements about Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) in the context of the shared responsibility model. Which two statements most accurately describe the distinctions between these service models and their applicability to the company's scenario? Choose the two best options.
A
IaaS provides the highest level of control over the operating system and middleware, requiring the customer to manage these components, while Azure manages the physical infrastructure. This model is ideal for scenarios requiring specific OS or middleware configurations to meet regulatory compliance.
B
PaaS offers a managed environment for application development, with Azure taking care of the infrastructure and platform. This allows the company to focus on developing applications and managing data, significantly reducing operational overhead, though it may limit customization of the underlying platform.
C
SaaS delivers fully managed software applications, with Azure handling all aspects from infrastructure to application. This model minimizes operational overhead the most but offers no control over the application's infrastructure or platform, which might not be suitable for applications needing specific compliance configurations.
D
All three service models (IaaS, PaaS, SaaS) provide identical levels of control and management responsibilities, differing only in the services they offer. The selection among them should be based purely on the company's preference for service type, without considering compliance or operational overhead.
E
None of the above accurately describe the distinctions between IaaS, PaaS, and SaaS in the context of the shared responsibility model and the company's objectives.
