AWS Free Tier Hours Calculation

0

I signed up for the AWS Free Tier service, my instance was created on 06/08/24. And today, 06/22/24, I received an alert saying that I consumed 659 hours! How is this possible? I would like to understand this calculation...

Amazon Elastic Compute Cloud = 659 Hrs Amazon Virtual Private Cloud = 645 Hrs I have Elastic IPs

Hello.

Are you launching two EC2 instances using an instance type eligible for the free tier?
In this case, the boot time is calculated for two machines, so it should be closer to 659 hours.
To check how many EC2 instance are running in your AWS account, we recommend checking the global view from the URL below.
If two machines are running, the execution time will be as expected.
https://us-east-1.console.aws.amazon.com/ec2globalview/home?region=us-east-1#

  • No, today I only have 1 instance. On the day I created the first instance... but Linux was damaged... so I deleted it... and created a new one on the same day... and since then, I only have 1 instance.. That's why I'm so intrigued by calculating time...

  • Can you check the global view and confirm that only one instance is actually running? For example, have you ever accidentally started up in a different region? https://us-east-1.console.aws.amazon.com/ec2globalview/home?region=us-east-1#

  • You were right. Through the link you send me... I found 2 instances... 1 running in São Paulo (which I didn't know about and I must have created by mistake) and 1 running in the USA (which is the instance I've been working on since the day 06/08/24).

    Thank you very much!
