An enterprise wants to deploy an email service for its employees without installing or maintaining any servers on-site. Which service model should the enterprise consider using?
Software as a Service (SaaS)
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS)
The enterprise should consider using Software as a Service (SaaS), as it allows them to subscribe to software services such as email without the need to install or maintain server hardware and software on-site. The cloud service provider handles the management, maintenance, and security of the service. While Infrastructure as a Service (IaaS) provides virtual computing resources that the enterprise would still need to manage, and Platform as a Service (PaaS) offers a development platform without pre-built software solutions like email services.
