In a load-balanced environment where multiple servers (nodes) handle incoming requests, caching introduces some additional considerations:

Distributed Caching:

Traditional in-memory caching (like ASP.NET cache) is local to each server. In a load-balanced scenario, this means that each server has its own cache.
To ensure consistency and efficiency, it’s often beneficial to use a distributed caching solution that synchronizes cached data across all servers. Examples include Redis, Memcached, or a distributed cache provider like Microsoft’s Azure Cache for Redis.
