What are some practical design concepts that are often missed in interviews?

My thoughts:

1. Logging
2. Tracing (requests go from one service to another, and you need to debug or report how they did)
3. Refactoring Designs
4. Testable design
5. Business and Engineering Metrics (Dashboards like Graphana)
6. Alerting

7. Outage or Incident Management (Root Cause Analysis?)
8. Handling memory overflow
9. Exception handling
10. Containerisation
