have correct connection strings, API keys, and so on, for publishCloud service configs have correct connection strings, API keys, and so on, for publish

Logging level has been set to Verbose initially (particularly for new systems and major changes) to quickly diagnose any problems, and changed to Error once the system is stable to save on the storage space
The website and cloud services have the starting instance count configured correctly, and auto-scale has been set up

A database backup strategy has been implemented
Databases have been updated with the latest migration scripts
