French Software


AUMERIAL is a French software publisher and IBM partner founded by Laurent Rouillot.

Our aim is to provide comprehensive tools, enabling IBM i users to modernize and future-proof their infrastructures, while developing modern, efficient and sustainable applications to meet the current and future needs of professionals.

Laurent Rouillot began his career in 1984 on IBM34 and IBM36, with several stints on IBM38. Present at La Villette in June 1988 when the AS400 was announced, he was the first in France in November 1988 to perform a direct conversion of indexed sequential files from a 36 to an AS400 database. Convinced that this was the best system, Laurent ROUILLOT has devoted a significant part of his career to working on this machine.

At a time when easy-to-use graphics tools were becoming increasingly popular, he was aware that the AS400's old-fashioned image was no match for its qualities. For 15 years, he searched in vain for an integrated modernization tool that would match the machine's DNA. In 2004, he carried out his first tests on the suite offered by Visual Studio 2003, based on the .NET Framework, released a year earlier. From then on, he continued to improve the .NET - AS400 (then iSeries and IBM i) relationship, culminating in his first packaged product: LINK2i. His aim was not to market software, but to provide a toolbox to meet the demands of his customers, who were often stuck with recalcitrant modernization products.

In 2017, after the presentation of a prototype at CEBIT in Hannover, and given the very favorable reception of the concept, he finally took the decision to turn it into a commercial solution. This was followed by 6 years of R&D, culminating in NTi, which regularly integrates new features from IBM i and .NET, opening up to other OSes, containerization and AI.

A market introduction now recognized and approved by IBM, propelling the AS 400 or IBM i into a sustainable, modern future.

Rémi Rouillot Société Aumérial

I decided to develop the tool needed to make IBM i and .NET work together, because the integrated aspect of the latter fits perfectly with the IBM i mindset.

The specification was the result of examining the weak points of all existing modernization solutions. For technical reasons, our first product, LINK2i, was dependent on Windows. With the arrival of NET 6, we were able to remove this dependency and offer very low-level access regardless of the environment.

It certainly deserved a new name: NTi.

It's worth noting that this latest round was carried out by Rémi, our 26-year-old CTO. Proof that the IBM i is not a machine for old-timers. Still, I don't think Rémi would have invested in RPG outside of his own personal culture.

And tomorrow ?

The IBM i - At the beginning

The IBM i, formerly known as the AS/400 and iSeries, has long been the cornerstone of enterprise systems, renowned for its reliability and security.

However, before recent technological advances, it was often perceived as a closed and rigid system, difficult to integrate with modern technologies.

Difficulties that could be encountered included rather complex data management, user interface constraints, and a certain rigidity that didn't allow ideal adaptation to changing and evolving market requirements. Also, users sometimes found it difficult to integrate the IBM i with new platforms and programming languages, thus limiting the full potential offered by this formidable machine.

The IBM i - The Era of Modernization

Today, IBM i has evolved into a more open and versatile system. Thanks to continuous updates and the support of a dynamic community, it now offers better integration with web and cloud technologies, greater ease of use, and increased flexibility.

These developments, supported by an active and dynamic community, now enable better integration with web and cloud technologies, while maintaining a high level of security. IBM i thus remains a solid and essential pillar for businesses, combining legendary security with modernized capabilities.

The combination of traditional reliability and extreme resilience makes it ideal for a wide range of enterprise applications, from ERP systems to web solutions. So today, it's no longer a question of abandoning what's been tried and tested, but rather of keeping what works, avoiding the risks and costs associated with a complete system replacement.

The IBM i & NTi - In tune with the times

Enrich the IBM i ecosystem, and make it easily accessible to everyone? This is now possible thanks to our NTi data access provider, who is opening up the platform to a panoply of modern, and above all, multiplatform development tools. A small revolution in terms of accessibility and interoperability.

By fully integrating with .NET, it overcomes traditional architecture limitations, facilitating the execution of .NET / IBM i workloads in modern, diversified environments, beyond traditional VMs, guaranteeing significant savings and a marked improvement in TCO.

Access to IBM i data and programs is simple with NTi. It's now possible for anyone to get to grips with this platform without any special skills. This means that the development of new business applications, websites, AI-embedded applications and much more is within everyone's reach in record time.
