The London Stock Exchange needed a scalable, reliable, high-performance stock exchange ticker plant to win more trading business and new customers and 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. The exchange used the Microsoft® .NET Framework in Windows Server® 2003 and the Microsoft SQL Server™ 2000 database to build the new Infolect® system and has achieved 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.
