My approach to SaaS architecture

Building scalable SaaS architecture

Good architecture is invisible when done right. Here's how I build SaaS products that scale smoothly.

I start with multi-tenancy from day one. Using Laravel's built-in scoping and my proven patterns, adding new customers requires zero architectural changes. The system scales naturally.

Every external service is abstracted. Payment processing, email delivery, file storage - all behind interfaces. Switching providers or adding new ones is trivial. No vendor lock-in.

I implement caching strategically. Database queries, API responses, and computed values are cached intelligently. Response times stay fast as data grows.

The queue system handles all heavy lifting. Reports, exports, emails - anything over 2 seconds goes to a queue. Users get instant feedback while work happens in the background.

Monitoring is built in from the start. Performance metrics, error tracking, and usage analytics provide early warning of issues. We fix problems before users notice them.

This architecture has powered applications from 10 to 10,000+ users without major changes. Smart decisions early pay dividends forever.
