In Cloud, we have 3 popular concepts which are:
- IAAS (Infrastructure As A Service)
- PAAS (Platform As A Service)
- SAAS (Software As A Service)
Since Microsoft 365 suite is hosted at Microsoft Cloud, it falls under the SAAS category.
One of the criteria for SAAS is we don’t have to install the application on the server (be it on-premise or on Cloud) to utilize the application.
Take Microsoft SharePoint (available as part of Microsoft 365 Basic) as an example. Traditional Microsoft SharePoint requires us to install and configure the SharePoint software in a dedicated server to use it.
However, if we subscribe to Microsoft 365, we can straight away use Microsoft SharePoint after a successful subscription to the service.
