Exam 220-1101 topic 1 question 105 discussion

The question mentions migrating applications to the cloud, which indicates SaaS. Think of IaaS as hardware as a service.

This question is difficult because it only says "to the cloud". It doesn't say "to the cloud, managed by external company" (SAAS) or "to our own cloud managed by us" (IAAS) Im in between but leaning to C because most commonly when companies "move to the cloud" they are moving to Microsoft 365 or Google which is SAAS

C has to be the answer why others saying D?

SaaS (Software as a Service) is the cloud concept that provides access to software applications over the internet. This model is suitable for migrating common business applications such as email and file shares to the cloud, as it allows users to access these applications without having to install or manage them locally.

migrating common applications (not all) to the cloud, which indicates SaaS

Infrastructure as a Service (IaaS) is the correct answer for this question since the technical lead need to move all his organization's applications and servers to cloud. Is is like moving the data center to the cloud therefore it is Infrastructure as a Service.

When I think of IaaS it makes me think of a company needing hardware to do something like make their own website or server or something without buying the hardware. Whereas SaaS is like a server to store their things and use for their own use, rather than needing Infrastructure and hardware for something. However, I do see that BOTH could technically be right? It all depends on the way you read and phrase the question. So I think this question is dumb haha I was just swayed more towards SaaS but there are very good arguments for both in the comments here.

SaaS can provide service migration for fileshare. For example, Microsoft Azure offers a service called Azure File Sync that allows you to centralize your organization’s file shares in Azure Files and cache them on Windows Servers or Windows endpoints. This service enables you to access your data on-premises or in the cloud, and it provides a simple way to migrate your file shares to the cloud. Additionally, Microsoft Learn provides a guide on how to migrate files between SMB Azure file shares 1. The guide describes how to migrate files from one SMB Azure file share to another, which could be useful if you need to migrate from a standard file share to a premium file share to get increased performance for your application workload.

dis be C

Infrastructure as a Service (IaaS) is a cloud computing model where virtualized computing resources, such as virtual machines (VMs), storage, and networking, are provided over the internet by a cloud service provider. With IaaS, businesses can migrate their applications, data, and other IT resources to the cloud, eliminating the need to manage physical infrastructure on-premises.

Take this with grain of salt: Initially ChatGPT said C. SaaS was the answer. I then point out that the question asks that they want to move "ALL common business applications, including email and fileshares, to the cloud". ChatGPT then apologized (politely I might add) and then changed its answer to: D. IaaS (my initial answer)

I'd go with C https://azure.microsoft.com/en-us/resources/cloud-computing-dictionary/what-is-iaas/#Overview

The correct answer is D. IaaS includes storage, data, and applications while something like IaaS wont fulfill their need to store large amounts of data on the cloud provider.

The technical lead should use SaaS (Software as a Service) to migrate all common business applications, including email and fileshares, to the cloud. SaaS is a cloud computing model where software applications are provided over the internet by a third-party provider. Users can access these applications through a web browser without the need for installation or maintenance on their local devices. The SaaS provider is responsible for managing the software, servers, and infrastructure, allowing users to focus solely on using the applications. In this scenario, migrating email and fileshares to the cloud using SaaS means adopting cloud-based email and file-sharing services that are provided and managed by a cloud service provider. Examples of SaaS offerings for email could include Microsoft Office 365 or Google Workspace, while file-sharing services like Dropbox or Microsoft OneDrive are common examples of SaaS solutions

Software as a service (SaaS) is a cloud computing model that provides access to software applications over the internet. SaaS applications are typically hosted by a third-party provider and are accessed by users through a web browser. Email and fileshares are two common business applications that are often hosted in the cloud as SaaS applications. This is because SaaS applications are easy to use and manage, and they can be accessed from anywhere with an internet connection.

To migrate all common business applications, including email and file shares, to the cloud, the most suitable cloud concept to be used would be Software as a Service (SaaS), represented by option C.

The correct answer is C
