Lambda for NodeJs doesn't / won't run multiple requests in the same process but different V8 contexts at the same time?

That sounds wasteful, and imo makes Cloudflare's Serverless tech superior for strictly network-io bound workloads. Lambda, to be fair, supports way many event triggers and all sorts of runtime and user-space constructs, but still manages warm start times <10ms which is really impressive.

Cloudflare uses V8 Isolates feature and they build a lot of the API backends to follow the WebWorker spec. It's very efficient and well-suited for logic running in network calls at the CDN edge but limited to Node/JS code. [1]

AWS Lambda uses their Firecracker micro-vm tech which supports more runtimes, environments and triggers than just Node and also runs container workloads. [2]
