⚙️ System Design for AI in Production

Caching StrategiesA cache trades freshness for speed by keeping a copy of hot data closer to the request. The strategy is the write/read pattern: cache-aside (app fills the cache on a miss), write-through (writes go through the cache to the store), write-back (writes hit the cache and flush later). Eviction (LRU, LFU) and TTL decide what to keep, and cache stampede protection stops a popular expired key from hammering the backing store. CDNs are caches at the network edge. Applied-AI interviews probe it because LLM responses, embeddings, and retrieval results are expensive enough that caching is a first-class design decision.
