What is a SaaS?
definition
SaaS stands for Software as a Service. It delivers applications over the internet so users access them via a browser without downloading or installing anything locally.
The provider hosts the software, manages updates, security and data storage. Customers simply log in and use the tool, usually paying a recurring subscription.
Common examples include Google Workspace, Salesforce and Slack. This model replaced traditional boxed software that had to be bought once and installed on individual machines.
Using a SaaS is like renting an apartment instead of buying a house: you pay monthly, the landlord handles repairs and upgrades, and you can leave anytime without owning the building.
key takeaways
- SaaS runs in the cloud and needs no local installation or updates from the user.
- Access works from any device with an internet connection and a browser.
- Pricing follows a subscription model rather than a one-time purchase.
- The provider is responsible for security, backups and feature updates.
- SaaS products scale easily from solo users to large companies without extra hardware.
