fasthttp
Fast HTTP package for Go. Tuned for high performance. Zero memory allocations in hot paths. Up to 10x faster than net/http
Here's something most tutorials won't tell you: Fiber is actually built on top of Fasthttp, making it up to 10x faster than standard net/http implementations. That's like upgrading from a bicycle to a motorcycle without changing the way you ride!

> You know that Cloud Run is a Kubernetes PaaS, right?
Yup. Isn't it Knative Serving or a home grown Google alternative to it? https://knative.dev/docs/serving/
The key is I am not managing Kubernetes and I am not paying for it - it is a fool's errand, and incredibly rarely needed. Who cares what is underneath the simple Cloud Run developer UX? What matters for me is cost, simplify and understandability. You get that with Cloud Run, and you don't with Kubernetes.
