SaaS

What is SaaS?

SaaS stands for Software as a Service. It's software you reach through a browser, paid for as a subscription, with the provider running everything behind the scenes. No installs, no servers to patch, no version that drifts out of date on one laptop. You log in, it works.

SaaS sits at the top of the cloud stack. With IaaS you rent raw infrastructure and manage the operating system, runtime, and app yourself. With PaaS you get a platform to deploy code onto, and the provider handles the layers underneath. SaaS hands you the finished application and keeps the entire stack out of your hands. The trade is control for convenience. Gmail, Slack, and Salesforce are SaaS: millions of customers share one codebase, and a single deploy reaches all of them at once.

The model rests on multi-tenancy. One application instance serves many customers while keeping their data isolated. That's what lets a SaaS company ship a fix on Tuesday and have every user running it by Wednesday, and it's also what makes building one genuinely hard.

SaaS at Dallonses

We build SaaS products end to end, from the data model through the billing logic to the dashboard a customer actually opens every morning. The hard part is rarely the screens. It's tenancy, permissions, and making sure one client's data never leaks into another's, while the thing still loads fast under real load.

Companies bring us their custom web applications when an internal tool needs to become a product other people pay for. We work through the architecture with them, set up the deploy pipeline so a release reaches every tenant cleanly, and keep an eye on cost optimization so the infrastructure bill scales with revenue and not ahead of it. The product ships. The economics hold up.

Turning a tool into a product people pay for? Let's build it right.
