Software as a service means a cloud computing model that delivers software over the internet through a subscription-based approach. In contrast to conventional installations on local devices, SaaS allows users to access and utilize the software using a web browser. The hosting maintenance of servers, databases, and code is handled by the SaaS provider, freeing users from the responsibilities of infrastructure management. This model is valued for scalability, accessibility, and cost-efficiency, as users typically pay a recurring fee for their services.
