Since most people aren't doing enough waste monitoring in the first place, shrinking oversized instances should be low-hanging fruit to free up some budget

EC2 is a significant part of cost for most customers. So, rightsizing is essential to keep costs under control.

Interesting tool. How do you get the efficiency score among the $1000 spend users?

The tool is interesting. EC2 rightsizing means cost saving.

The "Efficiency" metric is very useful and I really like the web interface. This is a great tool!

looks interesting .. Doesn't AWS provide rightsizing recommendations?

AWS does provide rightsizing tools (https://aws.amazon.com/answers/account-management/cost-optim...). However, we find it bit heavy duty for many customers, as it involves S3, RedShift, etc. Some customers may want simpler ways to analyze their environments.

The tool looks very useful. Will give it a try.
