Reliability

Can it recover?

---

The Question

When it breaks, does it come back?

---

What To Check

1. Graceful Degradation

// What happens when X fails?
try {
  doX()
} catch {
  // Does it fail safe?
  return default
}

Check	Issue	Fix
No fallback	Everything dies	Add default
No retry	One fail = fail	Retry
No circuit	Cascade fail	Circuit break

2. Recovery

// Can it restart?
process.on('uncaught', () => {
  // Log and restart?
})

Check	Issue	Fix
No restart	Stay down	Auto-restart
No logging	Can't debug	Log it
No alerts	Can't know	Alert

3. Data

// What if DB fails?
await db.save(x)
// vs
await db.save(x)
.catch(log)

Check	Issue	Fix
No backup	Lost forever	Back up
No transactions	Partial	Use transaction
No validation	Bad data	Validate

4. Capacity

Check	Limit
Auto-scale	Yes/No
Max instances	[n]
Queue depth	[n]
