Google and Amazon have multiple data centers across the globe, and their cloud solutions span across all them.

So, latency is an issue in a "statefull" message stream even for Google/Amazon.

Every connection/relay/router point along the network will introduces a delay. It takes my PC 8ms to ping the DNS server of my ISP [crossing 4 devices], and 26ms to ping pcmagazine.com [crossing 17 devices].

To expect that a long data message would take less time to travel thru the internet, be processed and generate an acknowledgment is extremely doubtful.
