NTT DOCOMO, INC. (DOCOMO), the largest mobile operator in Japan, has adopted Oracle Cloud Infrastructure (OCI) to build its new development environment for ALADIN (ALl Around DoCoMo INformation Systems), one of the largest customer information management systems in the world. Using OCI, the system’s 300 developers can now build modern applications in a faster and more cost-efficient manner, while DOCOMO benefits from highly available and secure compute resources, as the company expands to broader telecommunications, internet, and smart life services. In addition, DOCOMO has moved its on-premises Oracle Database for database training to Oracle Database Cloud Service on OCI.
ALADIN supports DOCOMO’s more than 83 million subscriber base, handling all customer-related operations, such as membership and transactional data, credit checks, contract data, and assignment of telephone numbers. DOCOMO’s customer information is rapidly expanding alongside the mobile operator’s ‘d POINT CLUB’ reward points program, growing numbers of traditional cellphone subscribers, and new customer touchpoints, such as chatbots and smart devices. To meet this business expansion and enable faster delivery of better services, DOCOMO is modernizing the ALADIN development environment by moving it to the cloud. As part of this, DOCOMO built a new development environment on OCI to serve approximately 300 developers.
Tadaaki Yoshida, Information Systems Department, NTT DOCOMO, INC., said, “Our goal is to ensure that ALADIN, a mission critical system which serves as NTT DOCOMO’s customer hub, operates in a reliable manner and delivers an excellent customer experience. The new environment on OCI supports development, coding, and integration testing. Its roll out has quickly proven how we can optimize our costs and improve developer productivity and efficiency through containerization and automation. The Oracle Cloud Free Tier also has allowed us to build the new environment quickly and at a lower cost. We plan to move the entire development environment to the cloud as we prepare for the future migration of our commercial environment and are looking forward to the evolution of the services and technologies provided on OCI.”

Each developer now has a dedicated environment and the ability to flexibly change resources during peak and slow periods of development, eliminating the need to manually provision and shut down environments and providing the resources needed on demand. In addition to improving the productivity and efficiency of the developer team, DOCOMO also used Oracle Container Engine for Kubernetes (OKE) for containerization, and plans to leverage Continuous Integration and Continuous Delivery and Deployment (CI/CD) tools to further automate operational management
