Thanks for writing and explaining all of that! I’m sure one way or another there’s a workaround for everything. But my point was exactly that. The fact that you need workarounds hinders agility. I don’t disagree with the benefits.

BTW, about this “What happens when you got millions of connections at once (think slither.io scale)? At the end of the day you have to put it into something that can scale.”

API Gateway has a hard limit of 500 WebSocket connections per second. It can’t be increased! https://docs.aws.amazon.com/apigateway/latest/developerguide... —- That’s about the capacity of 1 C5.4XL instance :)

The whole scalability argument of API Gateway and Lambda is highly overrated IMO. There are all sorts of soft and hard limits, and you still have to monitor utilization of concurrency rate and invocation frequency and manually request limit increases when approaching them. Doesn’t sound much different than using EC2.
