Why may adding a cache in front of a service create a new risk?
- 1Caches always slow down every read under a heavy amount of load
- 2A cache removes the need for any capacity planning
- 3The system may survive only with a warm cache, failing on misses
Show the answer
Correct answer: The system may survive only with a warm cache, failing on misses
Explanation
If origin can't handle traffic without the cache, a cache failure or flush becomes an outage. Test origin capacity with a cold or bypassed cache.
