Cloud Architecture and Design
Question
A consultant is helping a large company migrate its development environment to a public cloud provider. The developers are working on a VDI solution. The development tools that employees utilize require greater control of the OS environment. Which of the following cloud types should the consultant implement?
Options
- ASaaS
- BPaaS
- CBare metal service
- DIaaS
Explanation
IaaS is the correct cloud service model when developers require full OS-level control, as it provides virtual machines where the customer manages the operating system, runtime, and all installed software.
Common mistakes.
- A. SaaS provides a fully managed application with no OS-level access, making it incompatible with environments that require control over the operating system.
- B. PaaS abstracts both the OS and runtime, restricting customers to application code and data management - not suitable when OS-level configuration is required.
- C. Bare metal service provides direct hardware access without a hypervisor, which is more control than needed for VDI and sacrifices the flexibility and rapid provisioning that IaaS virtual machines offer for a development environment.
