Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  IaaS (Infrastructure as a Service)

  Why it's wrong here

  IaaS (Infrastructure as a Service) provides fundamental computing resources such as virtual machines, storage, and networking over the internet. While a company could deploy and run its email server software on IaaS, it would still be responsible for installing, configuring, patching, and managing the operating system, email application, and all associated security. This model offers high flexibility but does not offload the operational burden of managing the email system itself, making it unsuitable for a company looking to move its email system without extensive management.

• ✗

  PaaS (Platform as a Service)

  Why it's wrong here

  PaaS (Platform as a Service) delivers a complete development and deployment environment in the cloud, abstracting the underlying infrastructure. It is primarily designed for developers to build, run, and manage custom applications without the complexity of maintaining the infrastructure, offering tools and services for application development. Moving an existing, pre-built email system to PaaS is generally not the intended use case, as PaaS focuses on application development platforms rather than direct consumption of off-the-shelf software.

• ✓

  SaaS (Software as a Service)

  Why this is correct

  SaaS (Software as a Service) provides fully managed, ready-to-use software applications delivered over the internet on a subscription basis. With SaaS, the cloud provider manages all aspects of the application, including infrastructure, platform, and software maintenance, updates, and security. For an email system, this means the company simply consumes the email service, eliminating the need for any on-premises servers or management of the email application itself, making it the ideal choice for offloading email infrastructure.

• ✗

  DaaS (Desktop as a Service)

  Why it's wrong here

  DaaS (Desktop as a Service) offers a complete virtual desktop environment delivered from the cloud to end-users over a network connection. This service allows users to access their personalized desktop, applications, and data from any device, anywhere, providing a consistent user experience. While users might access a cloud-based email service *from* a DaaS desktop, DaaS itself is a service for delivering virtualized user environments, not for hosting or managing the email system application directly.
