What is SaaS Meaning?
SaaS (Software as a Service) is a cloud computing model where software applications are delivered over the internet instead of being installed on local computers or servers. Users access the software through a web browser, while the service provider manages the infrastructure, security, maintenance, and updates.
In simple terms, SaaS means:
You use software online without worrying about installation, maintenance, or hardware.
The SaaS provider hosts the application in the cloud and makes it available to customers on a subscription or pay-as-you-go basis.
