There are two things that tend to ring true with AWS customers: The AWS web console has a rough developer experience and it is difficult to understand where costs are coming from. If these two things resonate with you, you may consider checking out http://vantage.sh/
Vantage is an alternative to the AWS Console that provides a clean user experience and an emphasis on where your costs are coming from. Think of it like Mint.com for your AWS account. When you link your AWS account it will look across all AWS regions and all AWS services and provide you with information.
The best part is that Vantage will stay in sync with your AWS account. This allows you to continue using infrastructure as code or the CLI to spin up resources then use Vantage to cross check that everything is appropriately provisioned and correct from a price perspective.
