Azure VM Deployment: IaaS vs PaaS
Note: The question is included in a number of questions that depicts the identical set-up. However, every question has a distinctive result. Establish if the solution satisfies the requirements. You are tasked with deploying Azure virtual machines for your company. You need to make use of the appropriate cloud deployment solution. Solution: You should make use of Platform as a Service (PaaS). Does the solution meet the goal?
Community Insight
The core trap is confusing application development platforms with raw compute infrastructure; Azure VMs provide virtualized hardware control, which defines IaaS.
This question tests the distinction between Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). It establishes that Azure Virtual Machines are an IaaS offering, not PaaS.
Many candidates incorrectly select 'Yes' because they associate any cloud resource with PaaS. This error arises from misunderstanding that PaaS abstracts the OS and underlying infrastructure, whereas VMs require the user to manage the OS.

Expert Analysis
Why the Answer Is Correct
Azure Virtual Machines are the quintessential example of Infrastructure as a Service (IaaS). In an IaaS model, the cloud provider supplies the fundamental computing resources like servers, storage, and networking, while the customer retains responsibility for managing the operating system, middleware, and applications. Since the scenario explicitly involves deploying Virtual Machines, the correct solution is IaaS, making the proposed PaaS solution incorrect. Therefore, the answer is No.Why the Other Options Are Wrong
Option A (Yes) is incorrect because Platform as a Service (PaaS) provides a complete development and deployment environment in the cloud, including operating systems, development frameworks, and database management systems. Examples include Azure App Service or Azure Functions. PaaS abstracts away the underlying infrastructure, meaning you do not directly deploy or manage Virtual Machines within a PaaS context; instead, you deploy code or containers. Confusing these models leads to selecting the wrong service tier.Community Comment Notes
The community consensus strongly supports Option B. As Tanat noted, PaaS is designed for developing and managing software applications without worrying about underlying infrastructure. AmalMOQ clarified that IaaS is the most basic category where you rent IT infrastructure like servers and VMs. Multiple users, including BeauChateau and ddponder, explicitly stated that Virtual Machines are IaaS, not PaaS or SaaS, confirming the technical classification.Exam Strategy
When asked about deploying Virtual Machines, immediately identify this as IaaS. If the question mentions managing the OS or raw hardware, it is IaaS. If it mentions hosting web apps or databases without server management, it is PaaS. Memorize the core examples: VMs = IaaS, App Service = PaaS, Storage/Blob = SaaS/IaaS depending on context.
Frequently Asked Questions
Why is Azure VM considered IaaS and not PaaS?
Azure VMs provide virtualized computing resources where the user manages the OS and software. PaaS abstracts the infrastructure, providing only the platform for code execution.
What is an example of PaaS in Azure?
Azure App Service is a common PaaS example. It allows developers to build and host web apps without managing the underlying servers or OS.
