AWS Free Tier usage limit - hit 85% limit after a month

The alerts you're receiving are per-service, so this means you've used 85% of the free tier allowance for this one service. The free tier for EC2, for example, is 750 hours per month, which is just over enough hours to run one instance for the whole month. Assuming you had these instances running continuously from October 4th, it would make sense that you had used 85% of your free tier allowance for EC2 for the month. This resets every month, so you will have 750 hours to use every month for the first 12 months.

More information on the free tier is available here: https://aws.amazon.com/free, and you can view your current free tier usage in the console here: https://us-east-1.console.aws.amazon.com/billing/home#/freetier

Hi, as described in https://aws.amazon.com/free/ you get an allowance per month, so it's probably just saying you used 85% of your month's allowance, but you get more the next month (for 12 months). The monthly 750 hours for EC2 and for RDS for example each allow for a single instance running 24x7 for just over 31 days.
