Building a SaaS product is different from building a traditional web application. The multi-tenant nature, subscription billing, and scale requirements demand specific architectural decisions.
Tenant Isolation Strategies
How you isolate tenant data has profound implications for security, performance, and cost. We'll explore shared database, schema-per-tenant, and database-per-tenant approaches with their tradeoffs.
Billing Integration Done Right
Subscription billing seems simple until it isn't. Usage-based pricing, plan changes, proration, and failed payments all require careful thought. Start with a robust billing architecture even if your initial pricing is simple.
Performance at Scale
When you have thousands of tenants, noisy neighbor problems and resource contention become real. Design for observability and have clear strategies for scaling different system components.
