Office365 is an example of which service?

Office365 is classified as Software as a Service (SaaS) because it provides users with access to software applications hosted in the cloud, which users can utilize over the internet without needing to manage the underlying infrastructure or platform. With SaaS, users typically access applications via a web browser, and the service provider takes care of all maintenance, security, and updates. This model allows for flexibility and scalability, with subscriptions that can adapt to an organization's changing needs. Office365 specifically includes applications such as Word, Excel, and Outlook, which are delivered on a subscription basis, embodying the characteristics of a SaaS model.
