Goroutines Explained: Concurrency Patterns You Actually Use
Go's concurrency model is elegant but easy to misuse. These are the patterns that consistently hold up in production services.

AjayWhere Goroutines Help
Goroutines shine when latency matters and work can be split into independent units without creating coordination chaos.
Worker Pools
Worker pools give you bounded concurrency. They are one of the safest patterns when requests can spike unpredictably.

Fan-out lets you do parallel IO. Fan-in gives you a clean way to merge responses back into a single result for the caller.
Shutdown Paths
