Different Cache Options (MemCache, Distributed Cache, new Hybrid Cache) in dotnet

Asp.net Core has traditionally offered two caching options.

1. In-Memory caching
2. Distributed caching

• In-Memory Cache with (IMemoryCache) is Fast, but limited to a single-server.
• Distributed caching with (IDistributedCache) works across multiple servers.

.Net 9 introduces HybridCache, that combines the best of both approaches. It prevents the common caching problems like cache stampede.

Hybrid-Cache

Important Feaures

• Two-level Caching (L1/L2)
  • L1: Fast In-Memory cache
  • L2: Distributed Cache (Redis)
• Protection against cache stampede
• Tag based cache invalidation
• Configurable Serialization
• Metrics and monitoring

L1 cache runs in application's memory.

L2 cache can be Redis,SQL Server etc.
