EC2 is cheaper for a lot of things at the scale of things that can run on 10 instances. EC2 is a lot more expensive when you get to the point you need to hire a person to manage your EC2 instances. That $80k a year employee buys you a LOT of appengine services. That is what you are paying for. Comparing EC2 and GAE isn't really fair because EC2 is IaaS and GAE is PaaS.

It looks interesting for applications with somehow "moderate" update rates / pushes, since you get the whole package from client to server apis, but in my case here, it looks really expensive. If i understand the pricing model right, i would pay 5 credits per message on a broadcast to 4 players (currently the maximum player size per game), 1 to the system and 1 for each player. One credit costs "only" $0.0001 (which makes $0.0005 per broadcast), which doesn't look much, but throughout a game, there are a few of those. Let's say each player performs every 4 seconds an action that requires a broadcast, results in 1 broadcast per second per hosted game. That would cost a lot of money. Guess that an ec2 instance would cost way less and running the game logic directly their would also reduce the latency and the load of other instances. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
