Case study: Subex Limited
Subex Limited, headquartered in Bangalore, India, is a leading global provider of Business Support Systems for communications service providers. In recent years, the amount of data that Subex has had to manage and analyze for telcos has grown from tens of millions of records to billions of records daily. To keep up with this enormous growth in data, Subex required a new technology architecture that provides the performance and availability to process these records in near real time. Subex is migrating from Oracle Database on Sun systems to IBM DB2 9.7 on IBM Power Systems to gain the scalability needed to support these large volumes of data for its clients. DB2 provided the stability and the processing capabilities required, reduced hardware requirements and offered flexible licensing models to reduce the total cost of ownership of its offering by up to 40 percent.
