latency percentiles (p50

- Define alerting thresholds for cache health (hit rate drops

latency spikes

- Document cache key schema with namespaces

versioning

- Cost optimization: Right-sizing cache instances

tiered storage (hot/warm/cold)

authentication (Redis AUTH

- High availability: Redis Sentinel or Cluster mode

Memcached replication

- Hot key mitigation: Local caching of hot keys

key replication across shards

- Cache stampede prevention: Mutex locks

probabilistic early expiration

- Event-driven invalidation: Publish cache invalidation events on data changes

scalable for distributed systems

- Database caching: Query result caching

materialized views

- Distributed caching: Redis clusters for shared state

Memcached for simple key-value hot data

- Application-level caching: In-process caches (e.g.

Guava

- CDN caching: Static assets

dynamic page caching with edge-side includes

- Implement cache hit rate monitoring

latency tracking

### 5. Monitoring

Failover

- Plan for cache stampede prevention using locking

probabilistic early expiration

- Calculate cache memory requirements based on data size

cardinality

- Configure eviction policies (LRU

LFU

- Identify hot data sets

Creative

- Design from the outside in: CDN layer

application cache layer

- Select appropriate caching technologies (Redis

Memcached

Creative

- Select optimal caching technologies based on use case requirements

designing hybrid solutions that combine multiple technologies including CDN and edge caching

- Ensure data consistency by designing invalidation workflows

eventual consistency patterns
