Beyond the lakehouse: Architecting the open, interoperable data cloud for AI

AI in the enterprise has become a strategic imperative for every organization, but for it to be truly effective, CIOs need to manage the data layer in a way that can support the evolutionary breakthroughs in large language models and frameworks. They need to move beyond traditional data architecture that is often rigid and siloed, which creates direct impediments to AI innovation and competitive agility.

That’s why there is a massive pivot toward AI powered open lakehouse architectures. Built on open formats and interoperable engines, the open lakehouse architecture unifies structured and unstructured data into a single, flexible architecture. Unlike legacy systems, it eliminates silos and supports real-time access, making it possible to power everything from traditional business intelligence to advanced AI and machine learning workflows.

The open data foundation: Beyond raw Iceberg to enterprise-grade control

For years, the vast scale of data lakes often resulted in “data swamps,” lacking the critical governance and performance necessary for enterprise-grade workloads. While open formats like Apache Iceberg offered a breakthrough by bringing transactional integrity and schema flexibility to cloud storage, they presented a dilemma for CIOs: embrace openness at the cost of fully managed capabilities, or choose fully managed services and sacrifice interoperability.

These issues are resolved by the current lakehouse evolution. Platforms like Google Cloud’s expanded BigLake deliver truly enterprise-grade open data foundations – elevating Iceberg to a comprehensive native storage format that benefits from automated operational efficiency and integrated data lifecycle management without sacrificing openness. This means organizations gain the best of both worlds: complete data ownership and the flexibility of open standards, combined with the fully managed experience and robust controls demanded by their most critical workloads.

Interoperable engines: Fuel every user on the unified data layer

An open data foundation’s full value emerges when it empowers all data practitioners with true engine independence. While analysts need high-performance SQL, engineers and scientists use Spark and Python for advanced analytics and AI. CIOs must ensure that these diverse workloads consistently use a single, shared data copy.

Unified runtime metastores are key to this interoperability. A single, serverless metastore – like the new BigLake Metastore, built on open standard APIs – serves as the central control plane for all data. It establishes a single source of truth for schemas, lineage, and access controls to dramatically simplify data governance and accelerate time-to-insight, and guarantees secure and uniform access across all workloads. It ensures that your diverse workforce can leverage their preferred tools, all operating on a consistent, well-governed data layer.

Unified catalogs: From passive inventory to active intelligence

Traditional data catalogs, mere passive inventories with scattered governance, cannot meet open lakehouse and AI demands. Modern, scalable, unified catalogs are now delivering automated data understanding, proactive quality and lineage for trusted AI, and actionable metadata for generative AI.

Modern unified catalogs (e.g., Google Cloud’s Dataplex Universal Catalog) use AI to map metadata across the full data estate—from lakehouses to operational databases and AI models. Their “active metadata” ensures robust governance, complete data-to-AI lineage, high data quality, and powerful semantic search. This dynamic intelligence is also vital for grounding next-gen AI experiences and building foundational trust in AI.

Bridging operational and analytical: Unlock the flywheel of activation

A pivotal architectural breakthrough is underway, bridging historically siloed operational and analytical data. Where slow and costly ETL processes caused latency and data duplication issues and hindered real-time decisions and AI activation, the modern open lakehouse breaks through these silos.

By using open formats on unified storage, organizations derive analytical insights and fuel real-time operations from the same data, eliminating complex ETL, data movement, and associated costs while leveraging comprehensive data richness.

This fusion enables, for instance, real-time fraud detection that triggers operational updates, or AI agents that deliver instant personalized recommendations from rich contextual data. Such seamless operational-analytical synergy on an open, intelligent foundation creates the “flywheel of activation” – data is ingested, analyzed, and immediately activated into core workflows. This creates a self-reinforcing cycle of continuous improvement, innovation, and competitive differentiation.

This is the true promise of the AI-powered data cloud: An agile, intelligent, and unified data foundation that propels businesses forward in the age of AI.
