Governance and compliance risk – once data leaves your perimeter, you lose direct control over how long it's stored, where it resides, and who can see it. A single mis-configuration or model-training clause could violate GDPR, HIPAA, or internal policy. 2. Technical debt – the day you need to swap providers, migrate regions, or delete a customer record, you discover tight coupling in schemas, pipelines, and security controls that were never designed for portability. 3. Technical debt - having to synchronize data between multiple vendors and your own systems, which can lead to data inconsistencies and increased complexity. @@ -45,10 +45,10 @@ Before we look at any vendor implementation, it helps to know the building-block | Layer | Open standard | Why it matters | | --- | --- | --- | -| Table formats | Apache Iceberg, Delta Lake, Apache Hudi, Parquet | Column-oriented, ACID-capable tables that sit in ordinary cloud storage and are readable by engines like Spark, Trino, Flink, etc. Iceberg’s spec is fully open, so any vendor can implement it—preventing lock-in and enabling multi-cloud lakes. | +| Table formats | Apache Iceberg, Delta Lake, Apache Hudi, Parquet | Column-oriented, ACID-capable tables that sit in ordinary cloud storage and are readable by engines like Spark, Trino, Flink, etc. Iceberg's spec is fully open, so any vendor can implement it—preventing lock-in and enabling multi-cloud lakes. | | Governance / access control | Apache Ranger, Open Policy Agent, Unity Catalog, Lakekeeper | Centralize table/row/column policies, data masking, and audit logs across dozens of engines and clouds—without embedding rules in every service.
