With nearly 2,300 stores, The Home Depot is the world’s largest home-improvement chain — a brand that professional contractors and DIYers alike have come to depend on. The home improvement industry continues to experience unprecedented demand and dramatic increases in online ordering accompanied by expanding consumer expectations for things like curbside pickup and same day delivery. The Home Depot’s decision to migrate to cloud-based infrastructure, including the migration of the company’s SAP applications on Google Cloud which began in 2017, has set it up for success in an increasingly digital world, and helped the company adapt to changing market conditions quickly. 

Interconnected retail at scale

Building on a strong customer-first philosophy, The Home Depot aims to create what it calls interconnected retail—allowing customers to shop however, whenever, and wherever they want. “So many companies are focused on omni-channel retail,” explains Sam Moses, Vice President of Corporate Systems. “At The Home Depot, we wanted to take it to the next level. Interconnected retail puts the customer at the center of everything and enables them to shop in store, online, or both. Customers can begin a transaction online and continue in-store, or vice-versa.”

To support this strategy, the company’s SAP environment needed to be more agile. Running  everything on-premises, from central finance to POS systems, meant that The Home Depot’s IT teams experienced redundancy and repetitive, manual processes. Their data warehouse needed an upgrade to process and analyze growing and increasingly diverse data sets. The Home Depot chose to migrate its SAP environment to Google Cloud to support both the velocity and scale needed for the business as well as critical analytics capabilities needed for its bold digital initiatives. “We chose Google Cloud to support our SAP implementation. Our decision had a lot to do with the relationship between Google Cloud and SAP and also for the applications and services that are offered by Google Cloud, like BigQuery, which are helping to enable data and analytics within our organization,” Moses explains.

After migrating its SAP applications—including S/4HANA, its customer activity repository (CAR), general ledger, e-commerce system, enterprise data warehouse and more to Google Cloud, the company now has the speed, scale and flexibility to tackle enormous spikes in the business, all while staying fully available for their customers. Additionally, The Home Depot was able to transform its financial systems and make them more agile to deliver critical information across multiple business functions in real time.

Maximizing data insights to support customer experiences

By migrating to Google Cloud, The Home Depot is leveraging Google Cloud analytics to build   the industry’s most efficient supply chain including more robust demand forecasting, supplier lead times, estimated delivery times and more, all while maintaining better security than before. “We experienced unprecedented change in our customers’ behavior and their buying patterns, which puts a lot of pressure on our supply chain,” explains Moses. “So having the ability to leverage data and analytics gives us insights to know exactly what it is that our customers need.” 

The company’s analysts now use BigQuery ML for machine learning directly against the company’s BigQuery data and use AutoML to determine the best model for predictions. The Home Depot’s engineers have also adapted BigQuery to monitor, analyze, and act on application performance data across all its stores and warehouses in real time—capabilities that were not as seamless in the on-premises environment.

With hundreds of projects on Google Cloud, The Home Depot’s cloud journey is well on track, but the company is always looking to the future. “As our customers’ needs have continued to evolve, and as technology has continued to evolve, our relationship with Google will continue to advance — to be able to innovate together, to be able to find new solutions together, to better serve our customers.”

When your data is siloed data across lakes and warehouses, it can be hard to transform outcomes with your data. Apache Iceberg is an open table format that provides data management capabilities for data hosted on object stores and enables organizations to run analytics and AI use cases over a single copy of data. A growing community of data engineers, customers, and industry partners are contributing, integrating, and deploying Iceberg, making it the standard for organizations building open-format lakehouses. 

To help customers on this journey, we announced support for Iceberg through BigLake in October, 2022. Since its preview, many customers have started building lakehouse workloads using Apache Iceberg as their data management layer, and this support is now generally available. 

Unify analytics, streaming and AI use cases over a single copy of data

You can use open-source engines to process and ingest data into Iceberg tables, and BigQuery can query those tables. Since the preview, customers have also used Spark, Trino and Flink to process Iceberg tables and make those tables available to their BigQuery users. Then, BigLake Metastore provides shared metadata for Iceberg tables across BigQuery and open-source engines, eliminating the need to maintain multiple table definitions. Further, you can provide BigQuery datasets and table properties when creating new Iceberg tables in Spark, and those tables become automatically available for the BigQuery user to query.

When implementing Iceberg lakehouse workloads, query performance is a top priority for data warehouse users. BigQuery natively integrates with the Iceberg transaction logs and leverages its rich metadata for efficient query planning. Query plans are designed to reduce BigQuery compute consumption by lowering the amount of scanned data, by optimizing joins, and by improving data-plane parallelism. The net result is that you get better query performance and lower slot usage when querying BigLake Iceberg tables. 

This GA release also adds support to provide automatic synchronization of table schema in BigQuery when the table is modified through an open-source engine. 

Engine-agnostic, industry-leading security and governance built-in

Customers have been telling us that building Iceberg lakehouses in a secure and governed manner is a top priority. BigLake support for Iceberg provides fine-grained access control, including row- and column-level security as well as data masking to simplify this. These features are designed to work independently of the query engine. During the preview, we expanded BigQuery to also support differential privacy for all tables including Iceberg. 

You can also define security policies on a BigLake Iceberg table using BigQuery. Security policies are then enforced regardless of the query engine used — BigQuery natively enforces these policies at runtime, and open-source engines can securely access the data using the BigQuery Storage API. The BigQuery Storage API enforces the security policies at the data-plane layer, and is offered via pre-built connectors for Spark, Trino, Presto and TensorFlow. You can also use client libraries to build connectors for custom applications. 

New use cases with multi-cloud Iceberg lakehouse

The open nature of Apache Iceberg lets you build multi-cloud lakehouses with uniform management of data. With this launch, you can now create BigLake Iceberg tables on Amazon S3, and query them using BigQuery Omni. BigLake’s performance and fine-grained access control features seamlessly extend to multi-cloud Iceberg tables, so you can securely perform cross-cloud analytics with BigQuery. We’ll extend similar support to Azure data lake Gen 2 in the coming weeks. 

Apache Iceberg’s format uniformity across clouds also enables new data sharing use cases to help you share data with your customers, partners and suppliers, regardless of which cloud they are using. BigLake Iceberg tables on Cloud Storage or on Amazon S3 can be shared through Analytics Hub and consumed via BigQuery or OSS engines via BigQuery Storage Read API, providing an open sharing standard and the flexibility to use multiple query engines. A notable example of this is the recently announced Salesforce Data Cloud data sharing use case, which enables bi-directional cross-cloud data sharing between Salesforce and BigQuery and which is powered by Iceberg.
