Software as a Service (SaaS) is a method of software licensing and delivery whereby software is licensed on a subscription basis and is hosted centrally. This type of software is also referred to as “on-demand software” or “software-as-a-service” (SaaS). The SaaS model offers a number of advantages for both businesses and customers, such as scalability, convenience, cost savings, and reduced maintenance requirements.
In order for something to be considered a SaaS, it must meet certain criteria. Specifically, it must have a software delivery model that is accessible over the Internet, it must be scalable, it must utilize a multi-tenancy architecture, and it must have a pay-as-you-go pricing model. By meeting these criteria, SaaS solutions can provide businesses with a cost-effective and convenient way to access the software they need.
