Today's data and AI landscape is clear: the most successful organizations will effectively leverage data and AI. However, executing this strategy has historically been challenging. In many enterprises today, organizations must integrate multiple systems: a data lake for unstructured data, an orchestration and ETL stack, one or more data warehouses supporting various BI systems, a dedicated stack for data science and machine learning, and yet another system for real-time analytics. Each of these components requires its own unique governance approach. This fragmented approach creates several challenges within an organization. First, data silos significantly increase costs inside of the organization, both financially and operationally. Also, inconsistent governance undermines trust in the data, making it difficult to determine what data is available and which source should be used for a specific analytics workload. Lastly, the use of multiple stacks, tools, and programming languages creates inefficiencies in collaboration between teams, such as data engineering, data analytics, and data science. These complexities drive up costs and make execution more difficult.

The Data Lakehouse

The Lakehouse architecture offers a more efficient solution. All data is first stored in the data lake, creating a unified foundation. A consistent approach is then applied to data storage, management, and sharing, ensuring uniformity across the system. On top of this, a single governance framework manages both structured and unstructured data. Finally, all data and AI workloads access this centralized source of truth through the same governance model, streamlining operations and improving data integrity.

Azure Databricks Lakehouse Platform

The Azure Databricks Lakehouse Platform, introduced in 2020, has become the standard approach for data and analytics across the Azure Cloud. Today, thousands of organizations, from large enterprises to startups, build their Lakehouses on Databricks. The benefits of this approach are well-documented. In collaboration with Nucleus Research, Databricks analyzed customer adoption using accounting principles to measure impact. The findings revealed an average ROI of over 480%, with payback periods for new workloads averaging just over four months. Also, customers reported significant productivity gains across their operations.

Components of the Azure Databricks Lakehouse Platform

Delta Lake

Delta Lake is the key to providing unified data storage, management, and sharing on the platform. One of its biggest strengths is its ability to support all major Lakehouse formats available today.
