SaaS is credited with igniting the cloud computing movement by proving that IT services might be made available through the Internet. Analysts today consider SaaS to be one of several subcategories of the cloud computing business, despite the fact that SaaS suppliers did not use the term cloud to describe their solutions at first. SaaS offers businesses and individuals a convenient, cost-effective way to access and utilize apps without the burden of installation, maintenance, and management. It provides flexibility, scalability, and the ability to focus on core business activities.
