City staff use cloud email similar to Microsoft 365 through a client, with no municipal servers to run for that mailbox service. Which service type should candidates identify?
Select an answer to reveal the explanation.
Short Explanation
City email that just works in Outlook or the web — without standing up mailbox servers — is classic SaaS. Productivity suites like Microsoft 365 are the poster child. If the city still ran the Exchange boxes end to end, that would not be the SaaS picture.
Full Explanation
Microsoft 365–style email is a standard SaaS example: a complete productivity application delivered as a service for end users. IaaS would imply customer-managed servers for the workload. PaaS is centered on application platforms rather than finished mailbox suites, and purely on-premises appliances are outside the SaaS service type.
