CompTIA Cloud+ (CV0-004)Cloud ArchitectureMedium
A cloud customer is using a public cloud provider and wants to ensure that they are only responsible for securing their applications, data, and operating system configurations, while the cloud provider handles the underlying infrastructure, network controls, and physical security. Which cloud service model aligns with this shared responsibility breakdown?
- AFunction as a Service (FaaS)
- BPlatform as a Service (PaaS)
- CSoftware as a Service (SaaS)
- DInfrastructure as a Service (IaaS)
Show answer & explanationAnswer & explanation
Correct answer: B. Platform as a Service (PaaS)
In the Platform as a Service (PaaS) model, the cloud provider manages the underlying infrastructure, operating systems, and network controls, while the customer is responsible for their applications, data, and configuration of the platform itself.
Why the other options are wrong
- A. FaaS abstracts even more, with the customer primarily responsible for their code.
- C. SaaS means the provider manages almost everything, including the application itself.
- D. IaaS requires the customer to manage the OS and network configurations above the hypervisor.
Shared Responsibility Model (PaaS)
In Platform as a Service (PaaS), the cloud provider manages the operating system, runtime, and underlying infrastructure, while the customer is responsible for their applications, data, and platform configurations.
- Provider secures 'of the cloud' (infra, OS, runtime).
- Customer secures 'in the cloud' (apps, data, config).
- Less customer responsibility than IaaS, more than SaaS.
Memory trick: For 'PaaS', the 'Platform' is 'Managed', you just bring the 'App' and 'Data'.
