Difficulty: EasyInfrastructure as a Service (IaaS)

An IT training academy plans to use Azure Virtual Machines to create temporary hands-on labs for students. When utilizing the IaaS model, is the customer responsible for configuring, updating, and patching the guest operating systems on these virtual machines?

Answer: Answer

Answer

Yes, the customer is responsible for configuring, updating, and patching the guest operating systems on the virtual machines.
In an IaaS configuration, the user manages the guest OS, runtime, and application layers, while the cloud provider manages the physical host and hypervisor.

Step-by-Step Solution

1
Identify the cloud model used in the scenario.
The scenario uses Azure Virtual Machines, which is an example of the IaaS model.
Recognizing the service category is necessary to determine the boundary of shared responsibility.
2
Evaluate the management duties for the guest operating system in this cloud model.
In the IaaS shared responsibility matrix, the cloud provider manages the physical hosts and underlying network, while the customer maintains the OS and applications.
This determines that patching the guest OS is a customer responsibility.

Key Concept

Under the Infrastructure as a Service (IaaS) model, the customer manages the operating system, middleware, and applications, including patch management.
