Google Unveils Cross‑Cloud Lakehouse Service Linking BigQuery to Amazon S3

Why It Matters

The ability to query S3 directly from BigQuery removes a long‑standing barrier to true multi‑cloud analytics, allowing enterprises to consolidate workloads without costly data replication. This shift could reshape procurement decisions, as organizations weigh the cost benefits of keeping data in the cheapest storage tier while still accessing high‑performance analytics. By championing the Iceberg format, Google also reinforces the momentum behind open standards that decouple compute from storage. If the service gains traction, it may pressure competing lakehouse vendors to open their APIs or adopt similar zero‑copy pathways, ultimately driving a more interoperable data infrastructure across the cloud market.

Key Takeaways

• Google’s new service lets BigQuery run SQL on Amazon S3 data via Iceberg, eliminating data movement.
• Brad Shimmin of Futurum Group called the integration a challenge to competitors' walled‑garden approaches.
• The offering is available immediately, billed at standard BigQuery on‑demand rates plus S3 egress fees.
• Open‑source Iceberg format serves as the neutral table layer enabling cross‑cloud queries.
• Early adopters are expected to be media and retail firms with large S3‑based data lakes.

Pulse Analysis

Google’s cross‑cloud lakehouse is more than a product announcement; it is a strategic signal that the era of siloed data platforms is waning. Historically, cloud providers have built ecosystems that lock customers into proprietary storage to drive revenue from data egress and compute. By exposing BigQuery to S3, Google flips that script, betting that the convenience of a unified query engine outweighs the marginal revenue loss from reduced data migration services.

The move also aligns with a broader industry trend toward open table formats. Iceberg, originally developed by Netflix, has become the de‑facto standard for managing large, mutable datasets in object storage. Google’s endorsement could accelerate its adoption, compelling rivals like Snowflake and Databricks to either integrate Iceberg more deeply or risk losing customers who prioritize flexibility over vendor‑specific features.

Looking ahead, the real test will be performance and cost parity. If BigQuery can deliver query latencies comparable to native S3 analytics tools such as AWS Athena, and if the pricing model remains transparent, enterprises may rapidly shift workloads to this hybrid model. Conversely, any hidden costs or operational complexities could dampen enthusiasm. The next few quarters will reveal whether Google’s lakehouse becomes a cornerstone of multi‑cloud data strategies or a niche offering for early adopters.
