Difficulty: MediumPlatform as a Service (PaaS)

A digital publishing company deploys its web application using Azure App Service, which is a Platform as a Service (PaaS) offering. Under the Azure shared responsibility model, the company is responsible for patching the web server software (such as IIS or Apache) and configuring the guest operating system, while Microsoft is responsible for the physical hardware and datacenter security. Is this statement true or false?

Answer: Answer

Answer

The statement is false. Under the Platform as a Service (PaaS) model, Microsoft is responsible for managing, configuring, and patching the guest operating system and the web server software (such as IIS or Apache). The customer is responsible for the application code and data.
The statement is false because in a Platform as a Service (PaaS) model like Azure App Service, Microsoft (the cloud provider) handles operating system patching and web server maintenance. The customer is only responsible for the application and its data.

Step-by-Step Solution

1
Identify the cloud service model described in the scenario.
The scenario specifies Azure App Service, which is a Platform as a Service (PaaS) offering.
Understanding the service category is necessary to apply the correct shared responsibility rules.
2
Recall the division of responsibilities under the Azure shared responsibility model for PaaS.
Under PaaS, the cloud provider (Microsoft) manages physical servers, virtualization, the operating system, and runtime environments/web server software, while the customer manages applications and data.
This establishes which tasks are handled by the cloud provider versus the customer.
3
Compare the statement's claim with the PaaS division of responsibilities.
The statement claims the customer is responsible for OS configuration and web server patching, which contradicts the PaaS model where Microsoft handles these responsibilities.
Comparing the claim to established rules determines if the statement is true or false.
