**Characteristics**: - Cloud-based - Subscription-based pricing - Multi-tenant architecture - Automatic updates - Accessible from anywhere

Architecture Considerations

Scalability

Your SaaS platform needs to handle growing numbers of users and data.

**Considerations**: - Database scaling - Application server scaling - Caching strategies - Load balancing

Security

Security is critical for SaaS platforms.

**Best practices**: - Encrypt data in transit and at rest - Implement strong authentication - Use role-based access control - Regular security audits - Compliance with regulations (GDPR, HIPAA, etc.)

Multi-Tenancy
