The author likes AWS Global Accelerator. The author likes GA mainly because it uses BGP anycast, which means that the packets drop into AWS' network at the closest AWS point-of-presence, instead of traversing the internet. The author's experience is that this feature of GA, when combined with always-on VMs that do not need to cold start, provides him low latency for a particular service he is running.

The author also mentions Cloudflare and Google App Engine, but rejects these because on those services he chose to use the lambda-like compute functionality and wasn't prepared for the cold starts. He doesn't appear to have tried using Lambda on AWS, or dedicated VMs with Google. Thus it is a slightly apples-to-oranges comparison.

Lambda@Edge unfortunately does not support provisioned concurrency, so you are bound to cold-starts as well (I tried, measured, and reverted before even going live with it).

I opened a request on GitHub that Global Accelerator support AWS AppRunner (persistent containers in Fargate VMs with HTTP/S gateway) as an endpoint. That'd cover all of OP's usecases (and the one that I also have): https://github.com/aws/apprunner-roadmap/issues/83
