Ask HN: Easiest User proximity based routing for apps

How do you deploy an app in multiple regions and ensure that the region nearest to region gets the traffic.

One way to do it with Route53 Latency based routine or geo based routing other is GCP Load balancer.

But is there another way to deploy an app in multiple regions?

So far all the systems I've seen involve deploying app in regions manually then using either DNS based or Load Balancer with Anycast IP.

Something as simple as:

```deploy app=hello_world regions=all scaling=auto```
