SaaS (Software as a Service) is a cloud computing model where software applications are delivered over the internet instead of being installed locally on a device. Users access SaaS applications through a web browser or app, usually via subscription or online access.
In cloud computing and business software, SaaS eliminates the need for users to manage servers, updates, or infrastructure. The service provider handles maintenance, security, and hosting while users simply use the software online.
For example:
- Google Docs allows users to create and edit documents online.
- Zoom provides video conferencing as an internet-based service.
- A CRM platform like Salesforce is accessed through a browser without local installation.
- Project management tools like Trello operate as SaaS applications.
Common technologies and concepts related to SaaS include:
- Cloud Computing
