Caching improves performance and reduces load on databases and services.
Options:
1. In-memory cache (IMemoryCache).
2. Distributed cache (Redis, SQL Server).
3. Response caching and HTTP cache headers.
Choose cache lifetimes and invalidation strategies carefully to avoid stale or inconsistent data.
Architecture impact: Well-designed caching can dramatically improve scalability of .NET Core APIs.
