AWS Free Tier - Services displayed as in use

0

Hello,

In the AWS Free Tier table, on the Billing Dashboard, you can see which free tier services you are using and how much you can still use before going over the free tier limit, I have 2 additional services listed, that to my (poor) knowledge seem to be from the S3 service, which I did not activate. They are the following: "Amazon Simple Storage Service" and "AWS Key Management Service". Having only launched 1 single EC2 instance, all within the free tier limits, is it normal to have these 2 other services listed?

Also in the AWS Billing Dashboard it shows that there are 5 total active services, is this normal, despite only using 1 single instance of EC2?

Thanks in advance.

Hello.

S3 also incurs fees for APIs such as List.
Therefore, if you access the S3 dashboard from the management console, it will be recorded in your bill.
https://aws.amazon.com/s3/pricing/?nc1=h_ls

If you use KMS for things like EBS encryption, it should be recorded as an active service on your bill.
https://aws.amazon.com/kms/pricing/

Regarding active services, in addition to EC2, services used by starting EC2, such as Data Transfer, are also considered to be counted because they are listed as charges.
If you are experiencing a large number of charges, we recommend contacting AWS Support under "Account and billing".

  • I have nothing in the "S3 Management Console" nor in the "KMS Console", as I've not used anything under both of these services, but still, they both show as being used under the free tier in the Billing Dashboard.

  • When you access the S3 and KMS console from the management console, the List API will be executed. This will appear on your bill.

  • So anytime you access any management page through console.aws.amazon.com, despite not actually using the service, it'll charge you/register as a "use" in the billing section?

  • Services that are billed by the number of API requests may be included on your bill. It will appear on your bill even if you are on the free tier. If you check the details of your invoice, it should probably look like this: kms

  • Yes, as @Riku_Kobayashi explains, for those services that are billed by the number of API requests, such as Amazon S3, normal pricing applies also when accessing the service through the AWS Management Console.

Hi EC2 is like a server, which use other services as well like IP address , EBS ( Block storage) etc.. So if you boot up an EC2 , it will auto use the other supported services. Hope this answer your question.

S3: 5GB/Month is free AWS Key Management Service :20,000 (free requests per month)

You can use this link to check the free usage and service name under free tier: https://aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc&awsf.Free%20Tier%20Types=*all&awsf.Free%20Tier%20Categories=categories%23security-identity-compliance

  • The Elastic Compute Cloud (referring to the 750h hours and 30gb/month) are both listed, as they are part of EC2 (service which I'm using), same goes for the AWS Data Transfer, however both services that I mentioned in the original post don't belong to EC2, but to two other services that I am not using nor have activated, even the console of both of them shows nothing active.

  • S3 is billed for storage(GB) cost and data access cost. When you use the Amazon S3 console to browse your storage, you incur charges for GET, LIST, and other requests that are made to facilitate browsing.

    For KMS, U need to check what operation you have performed.

    Suggest to enable cost explorer ( Free Service) and wait for 24 hours to get the cost component data of your service usage
