EMR waste check
EMR Previous Generation Instances

What it finds
EMR Previous Generation Instances: one of the EMR checks in the analytics optimization group. Checks in this group look for: analytics and streaming capacity that is idle, left running, oversized, or configured in a way that bills more than the workload needs.
Why it costs money
Clusters, streams and jobs bill while they exist, so a forgotten or over-provisioned one costs the same as a busy one.
How it is detected
Runs in the partner build and the paid hosted tiers.
Where this check runs
This check ships in the partner build, for consultancies that scan client accounts, and in the paid hosted tiers.
