Software as a Service (SaaS) is a cloud-based computing model which provides businesses with access to software applications hosted remotely and accessed through the internet. With this model, businesses can benefit from reduced costs, quick implementation times, and more flexible licensing models. SaaS also eliminates the need for expensive hardware purchases, installation and maintenance, making it an attractive option for organizations of all sizes. By delivering services via the cloud, SaaS eliminates the hassle of software updates, allowing customers to focus on their core business activities instead.
