How to reduce your AWS Config bill for volatile workloads

AWS Config costs can skyrocket for volatile workloads like Fargate tasks due to frequent resource creation and deletion. Each Fargate task launch triggers 4 configuration changes (ENI, VPC, subnet, security group), making Config costs exceed the actual compute costs. Switching from continuous to daily recording frequency can reduce Config costs by up to 1400% while maintaining Security Hub compliance, though it comes with trade-offs like missing some changes and higher per-change costs for non-volatile workloads.
