Rakuten Card Processes Credit Card Transactions 40% Faster, Increases Business Agility, and Supports Rapid Growth with Oracle

Rakuten Card Co., Ltd. is financial technology company and is part of Rakuten Group, an e-commerce platform provider in Japan. It provides credit card issuance, credit assurance, and credit loan services. As a ‘technology-driven’ player in the industry, Rakuten Card aims to improve customer experience by offering various online services—from email marketing to credit card application and account management.
  
With the Japanese government’s initiative to promote cashless transactions, Rakuten Card’s annual growth rate is 20%, leading to a sharp increase in credit card transactions. With such rapid growth and a changing business environment, Rakuten Card needed to replace its 25-year old enterprise system with a highly flexible system to meet customer needs and support future growth.
 
Business Challenge
  • Support exponential growth for credit card services by enhancing the performance of the legacy enterprise system to meet the demands of peak workloads, such as month-end credit card payment transactions 
  • Meet stringent migration timeline and minimize disruption to credit card businesses
  • Improve application development efficiency and lower costs by moving away from an outdated common business-oriented language (COBOL)-based system to a modern and open environment 
  • Enable rapid response to changing business environment by using a highly flexible cloud platform to self-detect root causes for system failures and reduce maintenance time
Results
  • Processed month-end credit card payment transactions 40% faster by seamlessly integrating Oracle Exadata, Oracle Exalogic, and Oracle Cloud at Customer in Rakuten Card’s data center and gaining dynamic scalability and load-balancing capability to cope with peak periods, such as Rakuten Group’s sales campaigns and events 
  • Saved a significant initial investment by providing the flexibility to easily move data and workloads between on-premises Oracle Exadata and Oracle Exalogic without requiring fixed configurations to process peak workloads
  • Migrated data from the legacy, COBOL-based system to the new enterprise system in just one day with Oracle Cloud at Customer and switched the entire system to the cloud in Rakuten Card’s data center within the strict three-day timeline
  • Increased operating efficiency by deploying an enterprise-grade Infrastructure as a Service (IaaS) with Oracle Cloud at Customer and allowing fast responses to not only the enterprise system but also web applications and other business operation systems
  • Ensured stable and continuous credit card business operation by using end-to-end management services in Oracle Cloud and enabling the company to quickly resolve system issues and minimize delay on credit card transactions
  • Accelerated application development by replacing the COBOL-based development environment with a highly versatile Oracle Cloud’s Java environment 
  • Saved time and costs for testing load performance with various engineered systems by improving the capacity to quickly process enterprise workloads in the on-premises cloud with Oracle Cloud at Customer 
  • Ensured error-free credit card transactions and eliminated inconveniences to customers, such as inaccurate charges, by confirming the data input from the legacy system and giving the identical output in the new system

 

Oracle Cloud at Customer is the only solution that met our requirements to complete the migration within the strict timeframe and meet PCI-DSS global industrial standards. We were also using other Oracle products, giving us the confidence to ensure a seamless and easy development environment.

— Hirofumi Iwasaki, Group Manager, Technology Strategy Group, System Strategy Department, Rakuten Card Co., Ltd.

Execution

Rakuten Card conducted a proof of concept for Oracle Cloud at Customer over a three-month period and migrated its legacy system to the new environment, which was built on cloud platform. Oracle Consulting played a vital role in the project and coordinated with 350 project members to develop and deliver the system.

“Deploying Oracle Cloud at Customer over other approaches, such as scaling up our mainframe or reconstructing a package solution, enabled us to meet the stringent deadline and unique needs of the credit card services business in Japan.” – Yosuke Nakagawa, Vice Department Manager, System Development Department, Rakuten Card Co., Ltd.
