Developing scalable and sustainable SaaS solutions starts with the right architectural decisions. Microservices architecture is one of the most effective approaches to achieving these goals.
Domain-Driven Design (DDD)
The DDD approach should be used to determine microservice boundaries. This approach includes:
- Defining Bounded Contexts
- Identifying Aggregate roots
- Modeling Domain events
- Creating Ubiquitous language
Event Sourcing and CQRS
Event sourcing and CQRS patterns offer powerful solutions for complex business processes:
Event Sourcing Advantages
- Complete audit trail
- Time travel capability
- Debugging with event replay
- System state reconstruction from any point
Multi-tenant Architecture
Multi-tenant support is critical in SaaS applications. Three main approaches:
- Database-per-tenant: Separate database for each tenant
- Schema-per-tenant: Shared database, separate schemas
- Shared database: Shared database and schema, separated by tenant_id
"The right multi-tenant strategy determines the balance between scalability and cost."
