Best for	ML and fraud/risk teams needing low-latency, training-consistent features deployed in their own cloud.	Teams already standardized on Databricks who want feature governance without adopting a separate tool.	Teams already building models on SageMaker who need a managed registry to reuse features across the ML lifecycle.	Teams already centered on BigQuery who want feature serving without moving data into a separate store.
