I recently received a $1,000 bill from AWS while running a small ECS/Fargate setup, and it caught me off guard. I expected compute costs to be the main expense, but they turned out to be the cheapest part. Instead, the biggest contributors to the bill were the NAT Gateway due to its baseline cost and data processing, the Application Load Balancer (ALB) with its associated costs, and miscellaneous logging and data transfer fees. To combat these expenses, I redesigned my architecture by removing NAT entirely, replacing the ALB with API Gateway and VPC Link, and simplifying my network setup. I'm curious about how others handle this situation: do you avoid using NAT or treat it as a standard cost?

Yeah, the NAT costs can really add up unexpectedly! One thing I discovered recently is a tool that helps you bypass using a NAT Gateway altogether; just run it on an EC2 instance. It can save you a lot in fees!
I switched to using CloudFront, S3, API Gateway, Lambda, and DynamoDB. This no-VPC method significantly lowers costs for me. Typically my only expenses are related to domain renewals and Route53!
That's a tidy setup, definitely something to think about. My ECS approach has been versatile, but this could lead to fewer bills!
Right? Keeping it serverless helps avoid tons of extra costs, especially with those always-on components.
I appreciate you sharing your experiences! It does feel like AWS's pricing around networking can be a bit confusing. It’s something to keep in mind when designing setups to avoid unexpected charges later.
Exactly! It's all too easy to overlook those networking costs until they hit you at the end of the month.
Totally agree! It's a learning curve that many of us face when working with AWS.
I often run into high data transfer costs too. It's sneaky how quickly they can add up, especially with logs and metrics. Have you thought about changing your AWS log storage class to save on CloudWatch costs?
That's a great idea! I didn't include that in my initial cost breakdown, but switching to infrequent access for logs could definitely help.
If you don't need high levels of redundancy, running your own NAT using an EC2 instance can be a cost-effective alternative. Also, if the APIs you call support IPv6, that can significantly reduce NAT charges!
True, self-managing a NAT might save money, but I prefer avoiding that operational overhead. I'll keep the IPv6 option in mind though!
Just be cautious with that, as it can involve more maintenance and management on your end.
That's super useful to know! I'll definitely check it out on GitHub.
