As a project manager overseeing an IT project, you need to select a cloud service model that provides end users with fully managed solutions accessible via the internet, where the service provider takes care of all underlying infrastructure and maintenance. Which cloud service model should you choose?
Software as a Service (SaaS) is the cloud service model that delivers fully managed applications to end users over the internet. In SaaS, the service provider handles everything from infrastructure to application maintenance, allowing users to access and use applications without worrying about installation or upkeep. Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet but requires users to manage operating systems and applications themselves. Platform as a Service (PaaS) offers a platform allowing customers to develop, run, and manage applications without dealing with the underlying infrastructure, but users are responsible for the applications they create. Anything as a Service (XaaS) is an umbrella term that encompasses various service models delivered over the internet but does not specifically refer to providing fully managed solutions to end users.
