I’m not sure whether this is the right place to ask this question, but I’d like to give Amazon RDS’s trial a go. Previously I’ve used Microsoft SQL Azure’s trial and they cut me off as soon as I overshot the limit, preventing me from paying a single cent.
However, with Amazon RDS’s trial, it seems that I will be charged as soon as I exceed their limits. I’d just like to know if there’s anything in particular I should look out for, that I might miss out, and be charged because of that.
Of course, I’d prefer it if there is a way for me to prevent me from exceeding the free-of-charge limits.
Many thanks…
As far as I know you can’t set a hard limit. As far as I can tell the only limits you can hit are the time one or the IO limit: RDS won’t magically grow your storage size or your instance size for you.
You can however setup a billing alert: amazon billing charges are available as a metric in cloud watch (amazon’s monitoring system), so you can create alerts base on them (for example to send you an email). You can set this up from the account activity page or you can configure the alerts as you would with any other cloudwatch metric.
