As part of its strategy to win more trading business and new customers, the London Stock Exchange needed a scalable, reliable, high-performance stock exchange ticker plant to replace its earlier system. Roughly 40 per cent of the Exchange’s revenues are generated by the sale of real-time information about stock prices. Using the Microsoft® .NET Framework in Windows Server® 2003 and the Microsoft SQL Server™ 2000 database, the new Infolect® system has been built to achieve unprecedented levels of performance, availability, and business agility. Launched in September 2005, it is maintaining the London Stock Exchange’s world-leading service reliability record while reducing latency by a factor of 15. Its successful implementation, with support from Microsoft and Accenture, shows the London Stock Exchange’s leadership in developing next-generation trading systems.
