OneLake Is One Drive For Data
- OneLake is Microsoft's 'one drive for data' that centralizes storage across a tenant so analytics artifacts live in one discoverable place.
- Microsoft manages underlying storage and regional endpoints, letting users access data via shortcuts while keeping data residency per region.
OneLake Handles Regional Data Residency
- OneLake uses regional endpoints and shortcuts so data can remain in-country for compliance while providing a single logical access point.
- The hosts liken OneLake to a managed collection of ADLS Gen2 storage accounts with Microsoft routing access to the correct region.
Plan For Cross-Cloud Egress And Compute Costs
- Expect egress and compute costs when reading data across clouds; plan for AWS S3 egress charges and Microsoft compute to access external Delta files.
- Optimize reads and partitioning to keep cross-cloud access economical.
