Unified Lakehouse Architecture: OneLake Delta Parquet at Scale

Consolidate disparate data lakes, warehouses, and operational silos into a single, open, multi-cloud SaaS lakehouse. GuruGroup designs certified Microsoft Fabric OneLake architectures using the Medallion framework, multi-cloud zero-copy shortcuts, and DirectLake mode for sub-second executive reporting.

Overview: Unify Storage, Compute & Semantics in OneLake

Enterprise analytics has traditionally required copying data across transactional databases, data lakes, staging layers, and proprietary data warehouse formats—leading to high storage costs, data drift, and governance nightmares.

GuruGroup builds modern Unified Lakehouse Architectures on Microsoft Fabric OneLake. Operating as the "OneDrive for data," OneLake enables every compute engine—PySpark, T-SQL, KQL, and Power BI—to access a single copy of data stored in open Delta Parquet format without physical duplication or complex synchronization routines.

Core Advantages: Modernizing to Unified OneLake

Key architectural advantages delivered by GuruGroup’s enterprise Microsoft Fabric Lakehouse implementations.

Zero-Copy Architecture

Eliminate duplicate data copies and ETL pipelines. Virtualize multi-cloud datasets into OneLake via native shortcuts without physical movement.

Open Delta Parquet Format

Prevent vendor lock-in. All lakehouse data is persisted in Linux Foundation open Delta Parquet format with ACID reliability and time travel.

DirectLake Sub-Second Speed

Power BI semantic models query Delta tables directly in OneLake, achieving VertiPaq in-memory performance without scheduled refresh bottlenecks.

Unified Governance & Purview

Automated sensitivity classification, data loss prevention (DLP), and complete end-to-end data lineage tracked from raw source to report visual.
