My employer's AWS footprint is 5000+ EC2 instances. We use CloudHealth for: - Reserved Instance recommendations & purchasing - typically 12 month partial upfront - CPU, Mem, Disk stats pushed up for EC2 & EBS to identify wastage & generate rightsizing recommendations - Reports generated that go to management of "Optimization Opportunities" in $ for all areas that report to them (this one has the greatest effect in getting things actioned) - Regular reports also go direct to application owners of potential optimisations on EC2, EBS, config, unused ELB, old snapshots, etc. We also have a tool that starts and stops instances for people based on a schedule tag, which saves us a LOT of money. We report on people not using it for dev / test / uat.
