Databricks Jobs compute is designed for scheduled pipelines, while All-Purpose compute is designed for interactive notebooks and exploration. Their DBU rates differ.
On AWS, Jobs compute costs about $0.15 per DBU and All-Purpose compute about $0.55 per DBU. The same scheduled pipeline can therefore pay more than three times the DBU rate when it runs on an interactive cluster.
Classic compute also produces a separate cloud-provider charge for virtual machines and storage. Compare the DBU and infrastructure portions when measuring total cost. Moving a scheduled pipeline to Jobs compute does not require changing its SQL or transformation logic, but cluster configuration and permissions still need to be tested.
