I´m quite new with Amazon Web Services. Some months ago, I created a m3.medium instance on demand. According to AWS EC2 prices, this instance is 0.077$/hour. This means 55,44$/month (november). However, I got a billing of 74.76$ (91.12$ with taxes).

I guess I have some service that I´m missing and maybe they are charging me:

In example, I have an Elastic Load Balancer. Am I getting charged for that? Actually, I have realized I had two ELB. It looks like I created it another one for testing purposes and I forgot it there.

I also have an Elastic Block Store (EBS) with 8GB of size. Am I getting charged for that? Do I really need it?

When I check my billing status, I don´t see any reference to these both two services. So, I guess they are included in the EC2 billing, right?

I don´t know where I got the idea that when you start an EC2 instances, an ELB and EBS was included with no additional charges.

As you can see, I´m quite lost with these services.

Billing information is available from the account menu (in the top-right, next to the Region menu). It will display a simple breakdown of charges by service:

More detailed billing information is available by clicking the "Bill Details" link (in the top-right). It will show a breakdown of charges by service for any selected month:

EBS charges are included under "Elastic Compute Cloud":

To answer your questions:

There is also a Free Usage Tier that includes 30GB of EBS storage each month in your first year (amongst other services). If you use services within this free tier, there will be no charge.

  • I didn´t see the details link. Now, It´s clear. The unexpected extra charge comes from the second ELB I created and forgot to remove. – Rober Dec 07 '14 at 11:26
