SaaS คืออะไร

If you have used Gmail, Netflix, or Spotify, you have used Software as a Service. Let us unpack what makes SaaS tick.

SaaS delivers software over the internet: the vendor hosts and runs it, you just open a browser. It is renting access, not buying a box.

Because SaaS lives on the internet, you reach it from any device, anywhere. No download, no install, often a mobile app too.

SaaS runs on a subscription model: a recurring monthly or yearly fee instead of a one-time license. Predictable for you, steady revenue for them.

The vendor handles all the maintenance: hosting, updates, and security patches ship automatically. You always run the latest version, effortlessly.

Most SaaS uses multi-tenancy: one app instance serves many customers. Your data stays isolated, but everyone shares the same infrastructure and codebase.

For users, SaaS means low upfront cost, access anywhere, no install or upkeep, and plans you can scale up or down as needs change.

For providers, SaaS brings recurring revenue, a global market with no physical shipping, one central deployment, and fast rollout of fixes and features.

SaaS is cloud-hosted, subscription-based, and vendor-managed. On-premise you install and run yourself: full control, but all the operational burden.

SaaS is everywhere: Google Workspace and Slack for work, Salesforce for CRM, Netflix and Spotify for streaming, Figma and Canva for design.
