15. Scalability Considerations
For Architects:
1. Don’t overload Database
2. Know your workload and design for scale out at all layers including
database
3. Watch out for State
4. Make a right decision on the data access technology
For Developers:
1. Avoid resource intensive operations on loops:
2. When there is a need to join a lot of tables, split the query and process
the data in the application layer
3. Acquire late and release early:
4. Avoid large objects in memory:
5. Use lighter objects for serialization:
6. Use asynchronous programming wherever possible:

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