Service-as-a-Service

Service-as-a-Service (SaaS) is a cloud-based delivery model where a provider hosts software applications and makes them accessible to users over the internet. Instead of purchasing and installing software on individual computers, businesses subscribe to these services, often paying a monthly fee. This approach reduces the need for infrastructure management, simplifies updates, and improves scalability. Common examples include email platforms like Gmail, collaboration tools like Microsoft 365, and customer relationship management software like Salesforce. SaaS allows organizations to access powerful applications flexibly and cost-effectively without managing underlying hardware or software maintenance.
