What is SaaS?
Software as a Service (SaaS) is a cloud computing model where applications are hosted and managed by a provider and accessed by users over the internet. SaaS eliminates the need for users to install, maintain, or update software, as the provider handles infrastructure, security, and updates.
How Does SaaS Work?
SaaS applications are hosted in the cloud and delivered via a web browser or API. The key components include:
- Cloud Hosting: Applications run on the provider’s cloud infrastructure.
- Subscription-Based Model: Users pay monthly or annually for access.
- Automatic Updates: Software is updated and patched by the provider.
- Multi-Tenancy: A single software instance serves multiple customers securely.
