What is a mainframe?

A mainframe is a high-performance computer specifically designed for secure, real-time transaction processing. Every day, mainframes all over the world process more than a trillion transactions. This level of performance has made the technology a popular choice in fields such as finance, industry, governmental agencies and IT service providers. 
Created more than fifty years ago, mainframes have continued to keep pace with technological developments.  They have opened up to new IT languages and new methods of intercommunication, thereby integrating into the ecosystem of modern data centers, while retaining the strengths that have enabled them, for decades, to process massive volumes of data in record time, while continuing to guarantee total security for users.

Mainframe, a tailor-made solution

When you choose a mainframe, you choose an environment suitable for your digital transformation:
  • You ensure the continuity of your core business while benefiting from the possibilities offered by new development environments and cloud services.
  • You optimize your costs and avoid the risks associated with migrations or redevelopment projects.
  • You benefit from a homogeneous solution, capable of combining its historical robustness and speed with the agility of modern development tools.
  • You benefit from a totally secure environment that is unrivalled in the market. Z systems require complete encryption of all incoming and outgoing data.
  • You offer the next generation of developers an exciting tool. They’ll love working with popular new IT languages and tools like Java, Node.js and Python.

Client testimonial

NTN, a global reference in the design, development and manufacture of bearings, uses the mainframe for a number of critical applications, such as purchasing, finance and production management, for the entire European group.
