Did Amazon say no to donating the service?
Actually, it was Red Hat who was considering donating the service -- but
we're still working out details. :)

Amazon just lowered all prices, do I did some some cost
estimates for
the hypothesis of running the bulk of Sugar Labs' public-facing
and
development infrastructure on EC2.
In 9 days, the machine running
http://activities.sugarlabs.org/
along
with a bunch of other low-traffic services received 85.8GB and
sent
103.3GB of data, for a total of 189GB transferred.
In one year, this would become 189/9*365 = 7665GB (7.6TB).
However, these statistics were collected in a period of
extraordinarily
low traffic, because schools are closed in Latin America:
http://sunjammer.sugarlabs.org/munin/sugarlabs.org/sunjammer.sugarlabs.org
-apache_accesses.html
Within two weeks, traffic will return from 150 to 800-1000
connections
per minute, a factor 6. Our traffic includes a number of things,
such as
backups, which won't grow as much. But we're also expecting the
popularity of aslo to increase over the next year, so I'd keep
the 6x
factor:
76665GB * 6 = 45990GB (46TB per year)
We're well within the 10TB per month range. So we can expect to
spend:
45990 * 0.15 = $6898.50
This is just for bandwidth. Amazon also charges for instance
hours
(circa $2000 per year per instance), disk space and IP
addresses. This
is the whole story:
http://aws.amazon.com/ec2/#pricing
Depending how fast one instance really is, I'd guesstimate that
running
a good chunk of Sugar Labs' development and public-facing
infrastructure
on EC2 instances would cost some $10-15K per year. Moving
everything to
the cloud would likely cost over $20K per year at current rates.
