The National Family Allowance Fund (CNAF) called on Atos to carry out the largest migration of a mainframe system in the world

The project for the Family branch of the Social Security Department constitutes the largest migration in the world from a legacy information system to an information system which is open, agile, more modern, and cheaper.

“The Atos Group is proud to have successfully supported CNAF in implementing this ambitious project, the largest migration carried out to date in the world, with a volume of 55,000 MIPS (million operations per second). This project is part of our strategy to support our clients with digital transformation. With the investment made in bullion servers and ad hoc software architecture, CNAF and its operators will benefit from the advantages of a powerful, scalable, and secure information system, while reducing their operating costs and energy costs,” said Pierre Barnabé, Managing Director for Big Data and Security for the Atos Group.

As well as the global increase in purely technical capacity and the general application of 100% digital services for beneficiaries, the modernization of these applications allows IT operating costs for the Family branch to be cut by €20 million per year. These gains will mean a return on investment by the end of 2017.

And finally, this solution is less costly in terms of operational maintenance. The energy consumption of the infrastructure has been cut by two thirds and the system is now able to deliver more than 120 million transactions and generate 3 billion SQL requests per day.

The project was completed in 24 months, according to the schedule (with deployment on the 102 Family Allowance Funds), in a transparent way for internal and external users, without freezing application developments.

“This is a great achievement. It took us two years to complete such a large-scale project. Now we are proud to announce its total success, which will allow us to make savings of 20 million euros per year and cut our IT carbon footprint by a factor of three,” said Daniel Lenoir, Managing Director of the National Family Allowance Fund.
