A cloud architect is designing a new application that will process sensitive customer data and requires strict control over the underlying infrastructure, including hardware and network configurations. Which cloud service model offers the most control over these aspects?
- ASoftware as a Service (SaaS)
- BInfrastructure as a Service (IaaS)
- CFunction as a Service (FaaS)
- DPlatform as a Service (PaaS)
Show answer & explanationAnswer & explanation
Correct answer: B. Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides the highest level of control over the underlying infrastructure, including virtual machines, storage, and networking components, allowing the architect to manage hardware and network configurations directly.
Why the other options are wrong
- A. SaaS offers the least control, providing only access to the application itself.
- C. FaaS is a serverless execution model, abstracting away almost all infrastructure management.
- D. PaaS provides a platform for development and deployment but abstracts away much of the underlying infrastructure.
Infrastructure as a Service (IaaS)
A cloud computing service model where consumers provision and manage fundamental computing resources such as virtual machines, storage, networks, and operating systems.
- Highest level of control over infrastructure
- Pay-as-you-go model
- Requires more management effort from the consumer
Memory trick: IaaS Gives You Iron Control.
