Rate Limiting in .NET with Redis

Hey everyone

I just published a guide on Rate Limiting in .NET with Redis, and I hope it’ll be valuable for anyone working with APIs, microservices, or distributed systems and looking to implement rate limiting in a distributed environment.

In this post, I cover:

– Why rate limiting is critical for modern APIs
– The limitations of the built-in .NET RateLimiter in distributed environments
– How to implement Fixed Window, Sliding Window (with and without Lua), and Token Bucket algorithms using Redis
– Sample code, Docker setup, Redis tips, and gotchas like clock skew and fail-open vs. fail-closed strategies

If you’re looking to implement rate limiting for your .NET APIs — especially in load-balanced or multi-instance setups — this guide should save you a ton of time.
