Software as a Service (SaaS) is a cloud service that provides users with access to a vendor’s cloud-based software. Users do not install applications on their local devices. Instead, applications are hosted on a remote cloud network accessed through the web or an API, and it is the service provider that maintains the servers, databases, and the code that makes up the application. The scenario of employees using a web-based email service aligns with the SaaS model because the service is fully managed by the provider and is available to the end-users via the internet without the need to manage infrastructure or platforms.
