CCDE: Cisco Certified Design Expert (Practical) — Question 82

Which service abstracts away the management of the operating system, middleware, and runtime?

Answer options

• A. IaaS
• B. PaaS
• C. SaaS
• D. BMaaS

Correct answer: B

Explanation

PaaS (Platform as a Service) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the underlying infrastructure. In contrast, IaaS (Infrastructure as a Service) gives users control over the operating system and middleware, while SaaS (Software as a Service) delivers software applications over the internet. BMaaS (Bare Metal as a Service) also requires management of the underlying hardware.
