I'm set a website using the Amazon free tier in an EC2 instance. The free tier is giving me 750 hours of EC2 Linux t2.micro instance usage. I would like to know how the instance hours are counted to ensure the usage doesn't exceed the free tier limit.
I suppose if my website is not down the instance should be running 24 hours a day which will result in a maximum of 24 hours x 31 days = 744 hours per month usage.
Is that the case?
The AWS Free Tier provides 750 hours per month for a t2.micro Linux instance.
Therefore, if you keep one t2.micro Linux instance running for an entire month, then there is no charge for Amazon EC2.
You could, alternatively, run two instances for half a month each, since that would combine to the same total hours.
EC2 instance usage is calculated by the second or by the hour, depending on which AMI you're using:
If your instance is per-second, then you're billed a minimum of 60 seconds each time an instance starts.
If your instance is per-hour, then you're billed a minimum of one hour each time an instance starts.
An instance is considered to be 'started' when it enters the running state.
