Sounds splendid.


Are aggregate functions supported?
Or is there a simple way to simulate aggregate functions?

SimpleDB had some growing pains for ~3.5 hours yesterday afternoon, which prevented me from accessing my test domain. The service was inaccessible due to a flood of "internal error" messages. After service restored at about 5:30 PM PST the sequence of my attributes was scrambled.

For the gory details see:

I'd like to hear from Amazon the details of what caused the problem and what the AWS folks plan as preventative medicine.

And in a tiny bit of shameless self-promotion, the Tarzan toolkit for PHP 5 has full support for SimpleDB -- including yesterday's new additions. Well-documented and easy-to-use.


I think the FREE trial is a significant shift in pricing strategy, and I also think that this is a good change.

A lot of developers are not decision makers, but they can influence the decision, if they have tried the technology and feel good about the technology. A free trial will definitely help. Although S3 is already successful, something similar on S3 side would help too.


I'm still not sure I understand SimpleDB. Its price structure still does not make sense to me.
Does SimpleDB's pricing work like EC2?

It looks like for EC2 they charge per machine hour which means that for a month of operating a website with EC2, I would have to pay for the 24/7/30 which is about $70.00 per month. That's a lot for me right now and anything more than that would be prohibitively expensive.

I am on a fixed income so I need to save money as much as possible. If I get started with SimpleDB and I get 25 hours free per month, won't that 25 hours be used up in the first day of operation? Or is each transaction to the database (the time it takes to run queries) timed and added up into minutes and hours?
