Mainframe applications work to dazzling onto Google Cloud

“Our mainframe hosted most business-critical applications and functions. It became unsuited to support our evolution; the infrastructure was a burden, and it was more and more expensive to operate and maintain.

By migrating our mainframe applications to a new infrastructure, we can now focus on the application side, and significantly reduce OPEX leveraging the Cloud economic model. The new system brings agility, flexibility, and scalability and other benefits offered by the Cloud.

Ambroise GRESSIER, DOSI, La Redoute Group

Increased reliability for PMU’s Production System

“Performance and availability objectives are met: 24/7 availability, 100% Fault tolerant System, and backup system available in 2 hours in case of loss of the primary site. "

"PMU’s business, application and infrastructure teams are once again in control of our company strategic system. Development processes have been fully renovated with the implementation of DevOps practices including continuous integration and automated testing. "

"The reduction in Total Cost of Ownership is spectacular. “

Paul Cohen-Scali, CIO, PMU

Business Model Transformation to support Club Med evolution

"We moved from a monolithic application designed for our point of sales before the Internet era, to a system designed to support new usages, business priorities, and future developments, especially with mobile computing, and channel expansion. "

"Replatforming has improved reliability, response time and load balancing. We can scale-out easily, we improved the scalability and flexibility of our infrastructure, and made it easier to manage and far less expensive.“

Transforming the  bookstore Supply Chain

To accelerate cycles and increase efficiency between thousands of points of sale and publishing houses, Interform modernized its legacy application supporting core processes. Replatforming this asset onto a virtualized infrastructure reduced IT run costs by 76%, removed out-of-date technology, and facilitated the transition to newer resources for IT Operations

OPEX savings, portability, and improved performance to increase value for customers

“Legacy Software and Hardware recurring costs never stop increasing over the years. With the maturity of Linux, cloud computing, and open source technology, the modernization of the technical foundation of HennerNet, our mission critical application, significantly reduces run costs and delivers better control in its future evolutions. “
