Atos opens the way to modernization

Application modernization effectively reconciles these two demands: by protecting the rich functionality and mainframe-class reliability of legacy applications, and using standard and open source technologies to slash TCO and turn these systems into a platform for innovation.
Atos designed the Liber software suite to open the way to rapid and controlled modernization. Liber facilitates the replatforming of legacy applications for open standards, replacing proprietary infrastructure technologies and transposing code into a more current language as required.

Make the most of digital opportunities

Digital opens up unprecedented possibilities when it comes to creating value: new offerings that capitalize on data intelligence; collaborative innovation with your customer and/or partner ecosystem; access to new markets and innovative services or subscription-based business models or ‘matchmaking’ platforms…
The only things limiting these opportunities – and the organization’s ability to seize them – are the agility, security and performance of their information systems.

Liber: software to support successful modernization

As an expert in large systems and open technologies, Atos offers a suite of software for an industrialized approach to modernizing application portfolios, especially replacing mainframe infrastructures, proprietary transactional monitors and batch.

Liber: also available as an appliance

For optimum performance and simplicity, Atos also offers Liber in the form of a mainframe-class appliance based on the bullion high-density x86 server. This industrial-scale package includes server, storage, OS, PostgreSQL database, Liber TP and Liber batch. Delivered pre-configured and tested, the Liber appliance offers a full range of power options and a scale-in architecture making it the ideal gateway between legacy systems and the Cloud.
