#9: Invest in failure isolation

Apps should check for all error conditions
- Act on them when you find them
- Requires developer training
Failure in one component shouldn't propagate
- Network failures not seen by router or network management layer
- Disk failure, not seen by application after write error
Catching errors late probably means data corruption
- Error has propagated through system
- May leave other unknown side-effects
