Seems so - at the minimum the EC2 customer would need to choose or
configure an image that has the autoscaling support.
It looks like the biggest 'pro' we can derive from the thread is that
GAE gives little-to-no entry effort, at the expense of large
limitations to developers.
I guess where I have the issue is, I would gladly trade the pain/
effort of limiting myself to the GAE platform's restrictions for
simply picking and image for use with EC2. I'm not saying I'm any
sort of special example, just that I'm assuming most other developers
who have serious requirements to build 'real' apps are going to find
the same limitations and just go with EC2.
The only persons that will stay with GAE are going to be those who
need to write a simple, small gadget, or run a guestbook someplace
free... from Google's perspective they would need to offer a bit more
to really make it a profitable platform yet... I'm willing to help
find those ideas as GAE is still in Beta, hopefully we might be able
to get some of those features in...
