Featured success story
The Bank of Tokyo-Mitsubishi UFJ (BTMU), Japan’s largest bank in terms of assets, with 40 million personal bank accounts and 500,000 corporate clients, needed to satisfy customer demand for access to financial services anytime, anywhere, through any device, and it sought to launch these new services using only its existing IT assets.
As a platform for SOA development, the bank adopted IBM WebSphere Message Broker, with its MQ-based, high-throughput messaging backbone which has a successful track record in the financial sector. The SOA solution employed the IBM zEnterprise 196 as its platform, divided by logical partitioning, with SUSE Linux Enterprise Server as the operating system.
With the SOA platform leveraging WebSphere Message Broker the bank has accelerated its ability to build services in response to business issues and has a service re-utilization rate increase of 18 percent.
“The SOA platform with WebSphere Message Broker was released initially to cover three systems and nine services. In two-and-a-half years, use of the platform has been expanded to 23 systems and over 150 services," says Mr Tetsuya Tagami, Systems Infrastructure No.1, Systems Division, Manager.
