Exam AZ-900 topic 1 question 82 discussion

App1 - PaaS App2 - IaaS

I think App2 should be Iaas. The key word in here is "Operating System"

Based on the requirements for App1 and App2, here is the recommended cloud service for each: App1: Use Platform as a Service (PaaS). Since you need to be able to modify the code of App1 and minimize the administrative effort of managing the operating system, PaaS is the ideal solution. It allows developers to focus on the application itself without worrying about managing the underlying infrastructure or operating systems. App2: Use Infrastructure as a Service (IaaS). App2 requires interaction with the operating system of the server. IaaS provides full control over the operating system and the virtual machine, making it a suitable choice for this requirement.

The Keyword is Host and you can't host a SaaS, so the Answer is IaaS.

App1 -- PaaS App2 -- IaaS, because of Directly interaction with OS in server is possible only in IaaS.

Here’s my take on this question: App1 (IaaS): Strictly assuming the sentence "Administrative effort to manage the operating system of App1 must be minimized”, it means there’s still some administrative os level management, even though it’s minimum. App2 (IaaS): agree with most of one here. “App2 must run interactively with the os system server” suggests it’s making low level os calls.

APP2 should be IaaS. Here is the hint-You are going to deploy!

App1 - Paas App2 - must be IaaS because it must interact with operating system

App1 : PaaS / App2 : IaaS

Keywords interact with OS of server and NOT client computer OS

paas, and iaas.

The answer is not right. It should be: App1: Platform as a service (PaaS) App2: Infrastructure as a service (IaaS)

App 1 PaaS App 2 IaaS

Para atender aos requisitos dos seus aplicativos, você deve usar os seguintes tipos de serviços de nuvem: App1: Plataforma como Serviço (PaaS) Motivo: Você pode modificar o código do App1 e minimizar o esforço administrativo, pois o PaaS gerencia a infraestrutura subjacente e o sistema operacional. App2: Infraestrutura como Serviço (IaaS) Motivo: O App2 precisa ser executado interativamente com o sistema operacional do servidor, o que é melhor atendido por IaaS, onde você tem controle total sobre o sistema operacional e a infraestrutura.

From ChatGPT-->In SAAS the azure resource can interact with Operating system or not? ChatGPT said: ChatGPT In Software as a Service (SaaS), the Azure resource cannot interact with the operating system. SaaS provides fully managed applications delivered over the internet, and the service provider manages the underlying infrastructure, including the operating system. Users interact with the software through a web interface or application but do not have control over or access to the underlying OS or infrastructure. So, We can confirm App2 - IAAS

App1: Azure VM (IaaS) - modify the code of App1, which implies that you’ll need direct access to the underlying operating system App2: Azure App Service (PaaS) - PaaS services abstract away the underlying infrastructure, allowing you to focus solely on your application code

Correct answers are: App1 - PaaS App2 - IaaS
