This is what I love about their free-tier. For some services, You get quite a bit of processing power per month for free for a year or so. These terms may have changed since I last read them. Still other services give you freemium resource usage. For example, I think CloudFront gives you a certain number of free cache-invalidations per month. I guess there's always the risk of someone hacking you, then eating up your AWS resources to mine coins. This could rack up a huge bill. I think this hacking risk is true for many cloud services, though. One way to prevent this is to use IAM users with limited resource usage, and basically freeze the root account. AWS is a lot less stressful to use when you assume a "nobody allowed" or "least privilege" approach. Sorry for the edits, I am drunk.
