Update documentation and state that AWS re-calculates sandbox cost once in 24 hours #445
Description
Hi,
The DCE has a concept of budget and it works in general, but not for short-lived sandboxes.
I would suggest to clearly state in the documentation that the budget doesn't make sense for sandboxes with duration less than 24 (actually even a bit more, because it depends on when the re-calculation occurs and when the sandbox was started) hours, because AWS Cost Explorer which is used to get information about cost of a particular sandbox updates it's information once in 24 hours and there is no way to make it more frequent according to AWS support.
A workaround would be to limit resources which are allowed to run and restrict expensive resources in the sandboxes using IAM Policies.
P.S. also the budget doesn't count AWS credits. Or rather it does count them and if there are AWS credits available, the cost of AWS sandbox is always Zero, regardless of it's usage. To get "real" cost of a sandbox, the credits should be filtered out.
