Do any of you have any guide or material to recommend that helps to maximize AWS cost savings. Other than AWS resources themselves?

Depending on your scale, it's likely worth at least talking to https://www.duckbillgroup.com/. If you're trying to reduce a bill, they know the intricacies of it better than almost anyone (particularly with all of the AZ and egress gotchas).

Hi @Swarna Mani, we have some resources at divio.com 1. Here's some mostly horror stories about what can go wrong with AWS/skyrocketing costs. 2. A more intro level guide to AWS costs 3. And a more in-depth guide on estimating cloud costs 4. We give free cloud advice to companies thinking about how to make their cloud setup better. Sometimes they decide to go with Divio, sometimes they don't. But just putting it out there in case you'd want to have a chat about what your company is seeing/what your goals are. The sales guys will kill me 😂 if they find out I didn't also tell you people usually save up to 60% with us because of optimization. I hope some of this is useful!

This is great. Thanks @Christina Harker
