Software as a Service is being demonstrated. Migrating on-premises email to a cloud-hosted email service means you’re using a ready-made email application that runs on the provider’s infrastructure and is accessed over the internet. You don’t manage or install the software, the servers, the storage, or the operating system; the provider handles maintenance, updates, and security. You simply use the email service, paying for and configuring it at a user level. This differs from Platform as a Service, where you’re given a platform to develop or deploy your own applications, and from Infrastructure as a Service, where you rent virtual machines and recreate the stack yourself. DaaS would not fit this scenario, since the focus is on using a software application (email) rather than delivering a desktop or data service.
