What is SaaS (Software-as-a-Service)?
Software-as-a-Service is one of the models of cloud computing that delivers software applications via subscription-basis or on consumption online. This simply means that with SaaS apps, an individual no longer requires access, installation, and management on local computers but can easily access through a web application. The management, resources, and support are instead dealt with by a third-party provider.

Advantages of SaaS

Employees can access their SaaS apps and data, which are securely stored in the provider's data center, even in the event of a natural or man-made disaster. These are some well-known SaaS platforms – Amazon Web Services, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure, and more.
