See why IMemoryCache breaks down across multiple app instances, then move shared cache state to Redis and wire it with .NET Aspire.
Engineering notes
Writing
Start with a series if you want a guided path, pick a topic for a broad area, or use tags when you're looking for something specific.

gRPC
What gRPC is, how Protocol Buffers and HTTP/2 fit together, and when it beats REST or WebSockets for service-to-service calls.
Broad areas
Topics
Use topics when you know the general engineering area, such as .NET, Kubernetes or distributed systems.
Specific labels
Tags
Tags cut across topics and series. They're useful for technologies and narrower ideas like Redis, caching, retries or observability.
