Exploded costs declared as No-Resource - sometimes 10 times higher then the day before

Hi! We use a lot of services such as EC2, Lambda, SQS, CloudWatch, CloudFront etc. Usually we spend about $60-70 per day. But on few days we reach peaks about $600-800 per day! The cost explorer declares it as "No-Resource". It seems it can be SQS, but I cannot explain. We use Laravel-Vapor for managing the lambda environment and its backend sayy samething about 6 Million queues invoked per month. Concerned to aws price list it shouldn't lead to hundreds of dollar even a few dollar. Does anybody know how I can check which service causes this extensive costs?

Thank you in advance! Best, Michael

Hi Michael,

There are some costs not bound to specific resources, like certain API calls or data traffic. But with the help of Cost Explorer you should be able to narrow down the source of your spend.

A very helpful function of Cost Explorer is the "Group By" function, directly above the chart. The first thing I would do is selecting "Service" as grouping option. That way you can nail it down to Lambda, SQS, CloudWatch, etc.
Another thing you should do is group by Region. Check if the spend is really at the location you are looking for it.

Depending on your account setup you can also try to open the invoice for this account, which also gives you a line by line explanation of the spend, grouped by service and region. You can find this option also in the Billing Dashboard.

  • Hi and thank you for your answer, but it didn't help. We got a credit budget for trying amazon services. The credit budget is melting like ice in the sun, but there are no specific information for what the credit has been used for. Only really payable services are on the bill or in the cost explorer chart. For example we generated a "Business Service Fee" about $500 for May, based on about $5000 used services. But which services exactly caused this amount isn't comprehensible. I see costs about $500-$600 for each day from 29. to 31. May. But if I group the services or charged by, I only see some dollars for EC2 etc. and $500 for Business Service fee. On the bill it isn't declared what caused the high business fee, because there are only records which has to be payed, all fees which has been offset are missed on the invoice. It is really strange and a real gamble.

You can also groupby ChargeType. There are some chrges such as credits, refunds, Tax etc that are not directly associated with resources.

I m in a similar situation where billing is not clearly answering where did all the requests came from despite the console not showing that much activity. My questions refers to sqs. I have 14 total queues of which 7 are deadletter queues. I have been testing a recently developed app with 1 user and I am getting >1 M requests per month billing. This number does not seem plausible considering I am using at max 50 requests per day with 1 user. There are usually 10 -20 messages per day being sent around. I don't know if this is a technical issue or a billing error. The sqs is connected to a lambda and everything works but the number is ridiculous and i have not launched the app yet. I am afraid what will happen with actual users. Any guidance on where to look for answers for this. The code is pretty straightforward and follows aws recommended style.

  • I understand this. Concerning AWS price list 1M requests should be cost $0.40. Regarding my costs with about $3.500 per month, it must be at least 9 billion messages. That would mean 3.500 messages per second, 210.000 messages per minute. Sorry, but if I don't get managed that I have to leave AWS.
