Experian moves critical data and tools to Oracle Cloud Infrastructure for a 40% performance lift and a 60% drop in costs.


As a global technology company and market leader in data and analytics, Experian is committed to being early adopters of any technology that might improve the power of data for our clients and consumers. As part of this, we have moved several data workloads from our on-premises data centers, our colocation facilities, and other public cloud companies onto Oracle Cloud Infrastructure. In every instance, we have increased performance by 40%, reduced cost by 60%, increased reliability, and increased resilience.

Business challenges

Experian is the world’s leading global information services company. During life’s big moments—from buying a home or a car to sending a child to college to growing a business by connecting with new customers—the company empowers consumers and businesses to manage their data with confidence. With 17,800 employees in 44 countries, Experian manages credit history data worldwide on 1.3 billion individuals and 166 million businesses.

The company’s business continues to evolve to deliver faster, better services for its clients and consumers. Experian uses technology and innovation to satisfy the real-time data demands of consumers and businesses. This enables the company to be fully prepared to act when the right moment does arise, whether that is helping individuals take financial control and access financial services, businesses to make smarter decisions and thrive, lenders to lend more responsibly, and organizations to prevent identity fraud and crime.

For example, once a credit balance is paid off, Experian enables a rapid rescore instead of waiting for the traditional 30-day time period. Producing fast updates to information requires a scalable and secure global data platform to help process ever-increasing amounts of data.

We strongly believe that OCI’s lakehouse is a game changer. It's the next generation of the cloud. It allows us to transform faster. It allows us to increase our performance. It allows us to reduce cost. But, most importantly, it allows us to have a bigger impact on society. We can process data faster in emerging markets to bring in new products faster.

Why Experian chose Oracle

Experian needed an open data platform with open source products and services to build vast data pipelines and process large amounts of data, including real-time events and traditional relational database systems. The company wanted to unify critical data and analytics from on-premises data centers, co-location facilities, and other cloud providers, onto a single lakehouse architecture.

Experian selected Oracle Cloud Infrastructure (OCI) for an end-to-end cloud suite of services to process data securely and at speed on a global scale.


Experian moved several data workloads such has fraud detection, call center analytics, financial analytics, and credit data in Brazil to Oracle Cloud Infrastructure’s lakehouse architecture, which spans Oracle Exadata Cloud Service, Oracle Autonomous Data Warehouse, Object Storage, Big Data Service, Data Flow, and Data Science. The company saw a 40% increases in performance, a 60% reduction in costs, and increased reliability and resilience.

Open source workloads on Spark and Hadoop from other cloud providers were migrated to OCI lakehouse without re-engineering or re-architecting, contributing to the significant cost and time savings. Additionally, Experian’s success in the migration to OCI lakehouse was supported by Oracle Cloud Lift Services, which provided guidance on planning, architecting, and prototyping to help deliver immediate value.

The unified global platform was significant for emerging markets such as Brazil and India, which need to process large amounts of data but don’t have the same financial resources that other regions have. “We can change the entrepreneur ecosystem that powers those economies. You will get that back tenfold if you get it right up front,” says Mervyn Lally, chief enterprise architect.
