SaaS is a cloud-based delivery model for software applications. Instead of installing and maintaining software on individual computers or local servers, customers subscribe to the software and access it through the internet. The SaaS provider is responsible for hosting the application, handling security, providing updates and maintenance, and ensuring availability. This model allows for scalable, flexible, and cost-effective access to a wide range of software applications, including customer relationship management (CRM), enterprise resource planning (ERP), and project management, among others.
