Shameless plug here. Working on an side hustle to help you monitor and measure your AWS spend: http://www.cloudforecast.io
You'll get a daily report that breaks down your cost for you via inbox with weather symbols indicating the health of your cost. Think of this like the weather you check every morning before you start your day. Our forecasting in our report is pretty accurate too!
Hit me up if anyone is interested with helping us and provide product feedback. We're offering a 60 day free trial for our first users so we can evolve from a reporting tool to a tool that help you save on AWS cost.
Would love to hook you all up: hello@cloudforecast.io
This post has been super helpful to figure out what we should start thinking about and what to build next!
