Kubernetes combined with KubeVirt enables the hosting of virtual machines (VMs) alongside

containerized workloads. This setup aligns with a specific cloud service model. Let’s analyze each

option:

A . Software as a Service (SaaS)

Incorrect: SaaS delivers fully functional applications over the internet, such as Salesforce or Google

Workspace. Hosting VMs using Kubernetes and KubeVirt does not fall under this category.

B . Platform as a Service (PaaS)

Incorrect: PaaS provides a platform for developers to build, deploy, and manage applications without

worrying about the underlying infrastructure. While Kubernetes itself can be considered a PaaS

component, hosting VMs goes beyond this model.

C . Infrastructure as a Service (IaaS)

Correct: IaaS provides virtualized computing resources such as servers, storage, and networking over

the internet. By hosting VMs using Kubernetes and KubeVirt, you are offering infrastructure-level

services, which aligns with the IaaS model.

D . Bare Metal as a Service (BMaaS)

Incorrect: BMaaS provides direct access to physical servers without virtualization. Kubernetes and

KubeVirt focus on virtualized environments, making this option incorrect.

Why IaaS?

Virtualized Resources: Hosting VMs using Kubernetes and KubeVirt provides virtualized

infrastructure, which is the hallmark of IaaS.

Scalability and Flexibility: Users can provision and manage VMs on-demand, similar to traditional

IaaS offerings like AWS EC2 or OpenStack.

JNCIA Cloud Reference:

The JNCIA-Cloud certification emphasizes understanding cloud service models, including IaaS.

Recognizing how Kubernetes and KubeVirt fit into the IaaS paradigm is essential for designing hybrid

cloud solutions.

For example, Juniper Contrail integrates with Kubernetes and KubeVirt to provide advanced

networking and security features for IaaS-like environments.
