HOTSPOT -
You plan to use Azure to host two apps named App1 and App2. The apps must meet the following requirements:
✑ You must be able to modify the code of App1.
✑ Administrative effort to manage the operating system of App1 must be minimized.
✑ App2 must run interactively with the operating system of the server.
Which type of cloud service should you use for each app? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Box 1: Azure Platform as a service (PaaS)
Organizations typically use PaaS for these scenarios:
Development framework. PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. Similar to the way you create an Excel macro, PaaS lets developers create applications using built-in software components. Cloud features such as scalability, high-availability, and multi-tenant capability are included, reducing the amount of coding that developers must do.
Box 2:
Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring, and office tools
(such as Microsoft Office 365).
SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organization, and your users connect to it over the Internet, usually with a web browser. All of the underlying infrastructure, middleware, app software, and app data are located in the service provider's data center. The service provider manages the hardware and software, and with the appropriate service agreement, will ensure the availability and the security of the app and your data as well. SaaS allows your organization to get quickly up and running with an app at minimal upfront cost.

App1 - PaaS App2 - IaaS
I agree. App1: Platform as a service (PaaS) App2: Infrastructure as a service (IaaS)
I think App2 should be Iaas. The key word in here is "Operating System"
The one thing that keeps me second guessing is that it would do that by default in SaaS, or am i overthinking it? I'll just trust chatgpt in this case and go for IaaS. Microsoft questions are a pain.
App1: You must be able to modify the code of App1, which implies a need for control over the operating system and software stack. Administrative effort to manage the operating system of App1 must be minimized, indicating a desire for platform management. Therefore, for App1, you should use Platform as a Service (PaaS). PaaS allows you to focus on your application code while abstracting away the underlying operating system management. App2: App2 must run interactively with the operating system of the server, which implies that you need direct access to and control over the operating system. In this case, you should use Infrastructure as a Service (IaaS). IaaS provides virtual machines (VMs) where you have full control over the operating system and can run applications interactively with it. So, the recommended cloud service types are: App1: PaaS App2: IaaS
but can we really modify the code in PAAS?

I think App2 should be IaaS. The question states that you are using Azure to HOST 2 apps. This makes me think these are custom apps that the company is moving to Azure. Secondly, there is no reason to bring up OS in a SaaS or PaaS solution scenario as the OS is abstracted in those service models. The usage of "interactively" is also confusing as any application you run will interact with the OS in some way; bringing this up makes it seem like a specific OS is required for the app. If that is the case, IaaS is the answer for App2, as you will need to run and host it on a VM with a specific OS that the user installs and maintains.
This question was in the last exam I've made (13/11/2023), and I answer correctly I guess. My respond: Paas. Iaas. I was reproved, got 783. Next try, I'll respond: PaaS. SaaS. Even though it seems wrong.
So what are the correct answer? I am confused.
App1 - PaaS App2 - IaaS
Correct answers are: App1 - PaaS App2 - IaaS
App2 is Saas, because the apps need to run in OS.. which mean you need to install the software so it can run interactively with OS.
Agree that app2 is IaaS
Paas and Iaas App2 must run interactively with the operating system of the server. Which type of cloud service should you use
If App2 must run interactively with the operating system of the server, you should use Infrastructure as a Service (IaaS) in the cloud. With IaaS, you have full control over the virtual machines, including the operating system, networking, and applications running on them. This allows you to deploy and manage your applications just like you would on physical servers, giving you the flexibility to run interactive applications as needed.
App1- PaaS App2- IaaS For App1, you should use Platform as a Service (PaaS). PaaS allows you to modify the code of your application and it minimizes the administrative effort to manage the operating system as the cloud provider manages the underlying infrastructure12. For App2, you should use Infrastructure as a Service (IaaS). IaaS provides you with the most control over the operating system, allowing your application to interact directly with it.
app2 should be IaaS as it will interact with the OS of the server
App2 should be IaaS
App1 - PaaS App2 - IaaS (must run interactively with the operating system)
My answer for App2 was IaaS, but when trying to understand MS logic, it's talking about the App2 (application that interactively run on OS). Application that run on OS should be SaaS.
