• Database Routing Based On Tenant

• Application Layer Auto Tenant Filter

• Tenant Based View Filter

Scalability Considerations


For Architects:

1. Don’t overload Database2. Know your workload and design for scale out at all layers including

database3. Watch out for State4. Make a right decision on the data access technology

For Developers:

5. Avoid resource intensive operations on loops:6. When there is a need to join a lot of tables, split the query and process

the data in the application layer7. Acquire late and release early:8. Avoid large objects in memory:9. Use lighter objects for serialization:10. Use asynchronous programming wherever possible:

Database Sharding


Multi-Tenancy Security Considerations


Verify for OWASP security

Have Tenant data isolation prevention right in the framework and do not leave it to developers

Have ACL control right in the framework

Provide Security controls to tenants such as Tenant specific encryptions

Provide flexible ACL control to each tenant

Have separate authentication keys for each Tenant outbound access such as keys for API
