What is Multi-Tenancy?
A software architecture where a single app serves multiple isolated tenants, reducing costs & improving scalability. Common in SaaS (e.g., Salesforce). Benefits: cost-efficiency, easy updates. Challenges: security, performance. Ideal for cloud apps.

Multi-tenancy is an architecture in software development where a single instance of an application serves multiple customers (tenants). Each tenant’s data and configurations are isolated from others, even though they share the same underlying infrastructure.
Key Characteristics of Multi-Tenancy:
✅ Shared Resources – A single application serves multiple tenants, reducing costs.
✅ Data Isolation – Each tenant’s data is logically separated for security.
✅ Customization – Tenants can often configure their own settings without affecting others.
✅ Scalability – Easier to scale since all tenants use the same system.
Common Use Cases:
- SaaS (Software as a Service) platforms (e.g., Salesforce, Slack)
- Cloud-based applications
- Enterprise software with multiple clients
Benefits:
✔ Cost-Effective – Lower operational costs due to shared infrastructure.
✔ Easier Maintenance – Updates and patches apply to all tenants at once.
✔ Efficient Resource Use – Maximizes server utilization.
Challenges:
⚠ Security Risks – Requires strong isolation to prevent data leaks.
⚠ Performance Concerns – Heavy usage by one tenant can impact others.
⚠ Complexity – Designing a secure, scalable multi-tenant system can be challenging.
