Found, explained, handed over.

Findings with a dollar figure attached, idle, oversized, orphaned, unscheduled and undiscounted spend.

01

Detect

ZopNight checks this automatically across AWS, Azure and Google Cloud, with read-only access to the account.

02

Explain

Every finding says exactly what to change: Move cluster workers to spot instances. Where the saving can be proven it is priced; where it cannot, the finding says so.

03

Fix

The finding opens with the fix already written out, step by step, so it is one ticket, not an investigation.

Applies to
Databricks Cluster on AWS, Databricks Cluster on Azure, Databricks Cluster on Google Cloud
The fix, by hand on AWS
  1. Confirm the workload tolerates worker preemption.
  2. Switch worker availability to spot-with-fallback; keep the driver on-demand.

These are the steps the finding carries in the product.
