Migrating legacy systems to the cloud remains one of the toughest balancing acts in IT. Every choice affects stability, cost, and trust at once, and what starts as a modernisation effort quickly turns into a negotiation between ambition and reality. Suddenly budgets rise, dependencies appear late, and timelines tighten as old architectures collide with new expectations. In the end, success depends on sequencing, ownership, and aligning business priorities with infrastructure limits, and not only on technical readiness. Making it work requires more than a plan on paper. Knowing which systems genuinely belong in the cloud, which can wait, and which should stay put shapes the entire roadmap and defines its success. Each refactoring decision sets the level of future flexibility, but it also drives cost and risk. The trade-offs between speed, sustainability, and resilience only become clear once migration begins and pressure builds. Let’s discuss how to plan migrations that stay on track, manage hidden dependencies, and handle downtime with confidence. Let’s also discuss how governance, testing, and vendor coordination keep progress visible and credible. Are you in? A closed conversation for those who turn cloud migration from a disruption into a long-term advantage.

CIOs today are being judged less as technology leaders and more as portfolio managers. Every euro is under scrutiny. Boards and CFOs demand lower run costs, higher efficiency, and clear ROI from every digital initiative. Yet, they also expect CIOs to place bets on disruptive technologies that will keep the enterprise competitive in five years. This constant tension is redefining the role. In this session, we go beyond FinOps and cost reporting to tackle the strategic financial dilemmas CIOs face.

AI coding assistants entered development teams quietly, but their impact grows by the day. What started as autocomplete now shapes architecture decisions, documentation, and testing. And when productivity gains are visible, so are new risks: security blind spots, uneven quality, and the slow erosion of shared standards. Teams move faster, but not always in the same direction. The challenge has become integration rather than adoption. And new questions have risen: how do you blend automation into established practices without losing oversight? When is human review still essential, and what should the rules of collaboration between developer and machine look like? As AI tools learn from proprietary code, where do responsibility and accountability sit? Let’s talk about how to redefine those workflows, balancing creativity with control, and protecting code quality in a hybrid human-AI environment. A closed conversation on where AI accelerates progress, where it introduces new debt, and how development culture must evolve to stay credible.

Zero Trust sounds simple on paper: trust no one, verify everything. But once you start implementing it, the fun begins. Legacy systems, hybrid networks, and human habits don’t read the manual. The idea is solid; the execution, not so much.

Arxus ensures that Resengo's reservation system is permanently available
Resengo is a Belgian digital company that develops online reservation systems. Primary target groups are restaurants, wellness centers, and sports & recreation facilities.The company has experienced significant growth in recent years. Resengo is now working on a new IT architecture to eventually transition completely to Microsoft Azure.
Resengo is a Belgian digital company that develops online reservation systems in-house. Primary target groups are restaurants, saunas & wellness centers, and sports & recreation facilities. Through their proprietary platform, Resengo registers more than 3.2 million online reserved place settings for restaurants, every month. Typically, for Resengo, companies put forward a complete offer: the actual reservation system with both the associated back office and the necessary plug-ins to link their customer's website with the system. For example, to find a restaurant nearby where you can make reservations through Resengo. In recent years Resengo has chosen to further develop their software with new automated marketing techniques, including inbound marketing. Their prospects can, for example, onboard themselves with a free trial version of our software. Our software has also been further developed with a Match & Go feature. This means that we bring the right guest to the right catering facility with the goal of providing a positive review of the customer to his/her contacts.
The success of our product depends on its availability. At Resengo, availability is closely linked to scalability. Arxus ensures that the applications are always available. This allows us to focus entirely on the development of the offering.Dirk Gypen: (CEO) - Resengo
In recent years, Resengo has experienced significant growth. The company now has over three thousand customers and registers/books 6 million place settings every month. Over 3 million of these are booked online. Across all sectors, this amounts to nearly 3 million reservations every month. Behind the scenes, Resengo often needs to move quickly. This has proven to be a problem in the past. Resengo was unable to cope with this itself and also did not have the possibilities to develop the necessary expertise itself. This year marks Resengo's nineteenth anniversary and all development is now done in-house. The ongoing challenge, therefore, is to ensure that older technology is continually replaced with new technology. All new applications are built entirely in the cloud. In the near future, Resengo aims to also migrate all the legacy code they are still using to cloud technology.
Resengo did not consider immediately moving everything to the cloud as the best option. For the time being the hybrid cloud is the perfect solution for them. They are currently also using Arxus' private cloud. Resengo is now working on a new IT architecture to eventually transition completely to Microsoft Azure. Microsoft Azure can support Resengo's growth with modern applications which are often available by default. To take maximum advantage of the capabilities of Microsoft Azure, they will eventually transition entirely to the Microsoft cloud. Ultimately, today's transition is also less costly than using custom applications in the private cloud.
A good mission, a clear vision, and shared values can connect and motivate people to achieve a common goal. Arxus tries to reflect this as much as possible in their daily work. Arxus aims to increase productivity, efficiency, and innovation in companies by relieving them of managing IT business processes with their application-centric cloud solutions. They want to proactively analyze business processes and automatically adapt cloud solutions to meet the changing needs of businesses. This means: providing the best possible experience on any platform or device. Arxus aims for an environment in which everyone feels at home and where colleagues become friends. They celebrate accomplishments. Success equals enjoyment. Arxus never stops learning and does not shy away from challenges. Innovation is key. But to help any organization move to the cloud, they prefer a no-nonsense and local approach. Being close to customers and getting the job done as a team is of paramount importance. Where others are targeting the moon, Arxus is already on its way to Mars.
Resengo relies on the services of Arxus for everything that has to do with the underlying infrastructure. In terms of infrastructure, the collaboration with Arxus offers Resengo an essential advantage. Arxus can also make good use of the knowledge network of Cronos, of which Arxus is a part. The company can fully focus on its core activities: the development of new functionalities and applications and, of course, customer support. Arxus has taken responsibility for the entire infrastructure component. This ensures that Resengo does not need to invest in machines or in infrastructure knowledge. Arxus provides this expertise. At the same time, Arxus offers guarantees of availability, performance, and security that would not be immediately feasible for Resengo under its own management. In the current hunt for talent, IT employees are very difficult to find. And then again: infrastructure expertise is not part of Resengo's core business. It works much better and more efficiently for them to meet the need for scalability via Arxus.
With Arxus, Resengo has a unique point of contact for any IT issue. Arxus has easy access to the broad ICT expertise of the entire Cronos Group. Whatever the question, there is always an answer. This not only gives Resengo a sense of security, it is also very convenient that we have all the necessary expertise at our fingertips via Arxus. Arxus is a partner who continuously thinks along with us and is on a journey together with us.Dirk Gypen: (CEO) - Resengo
