A Decade of Hyperconverged infrastructure: How Nutanix supported Accor in Building a Robust Foundation

A high-performance, stable, and scalable hyperconverged platform powering global hotel bookings.

For more than ten years, Nutanix has supported Accor in hosting its most business-critical applications, including its booking system. In an environment where 98% of bookings rely on IT and even the slightest downtime can cost millions of euros, the group found in Nutanix a stable, high-performance, and scalable infrastructure capable of supporting its evolution while securing its legacy workloads on-premises.

Key Benefits

The Challenge

Accor is a major global hospitality player, with more than 5,700 hotels and over 45 brands ranging from budget to ultimate luxury. While hospitality remains its core business, IT has become a central pillar, as nearly all bookings now rely on IT systems—whether through online portals, communication with hoteliers, or connections with major booking platforms.

Historically, Accor relied on traditional virtualization infrastructure composed of physical servers and storage arrays, using multiple hypervisors such as Microsoft Hyper-V, Red Hat solutions, and VMware. Over time, architectural issues began to emerge. Several I/O-intensive applications failed to function properly, resulting in frequent incidents, including corrupted VMs, unexplained reboots, and unstable cluster behaviour. The infrastructure required constant monitoring and significant proactive effort, without delivering the level of performance and reliability expected for an organization of Accor’s scale.

At the same time, the group’s most critical applications—including the booking system and other business-critical workloads—relied on costly Oracle machines, both in terms of licensing and hardware. With end-of-support approaching, Accor needed to rethink its entire technical foundation.

Accor faced a twofold challenge: maintaining high application availability while improving performance and flexibility to support the group’s growth and transformation. “Migrating our most critical application to a new technology was a gamble, but Nutanix delivered the stability, performance, and scalability we needed to move forward with confidence”, said Yann Hebuterne, Head of Project Delivery team within the IT department.

The Solution

The collaboration between Accor and Nutanix began in 2012, when the group was looking for a solution that could handle very high I/O requirements on a number of patching applications that needed to be optimized.

After several tests, the Nutanix hyperconverged platform quickly stood out, delivering 3-5x better performance than the legacy infrastructure. Initially limited to this specific use case, the solution gradually became central to Accor’s environment. The group then decided to migrate these business-critical workloads to Nutanix.

With Nutanix, Accor streamlined its infrastructure to around 130 nodes across some fifteen clusters. The Nutanix infrastructure hosts the most critical servers, including those linked to booking.

Virtualization followed a progressive path. The infrastructure initially relied on Hyper‑V and a Red Hat hypervisor before migrating to Nutanix AHV for Linux. For Windows, an intermediate phase required VMware, but as the VMware landscape evolved, everything eventually transitioned to AHV to unify the platform.

Today, Windows Server and Linux environments coexist on a Nutanix hyperconverged infrastructure that also hosts the group’s main databases. 

The Results

More than ten years after the first deployments, Nutanix has established itself at Accor as a solid, stable, and fully mastered platform. The transition to AHV marked a turning point, with a sharp decrease in incidents, VM corruptions, and unpredictable behaviour. 

Performance improvements have also been significant. During migrations from older clusters to newer generations, some application teams have seen 3 to 4x faster response times, according to Yann Hebuterne.

Scalability is another major strength of the Nutanix infrastructure. Expanding a cluster by adding new nodes is seamless—even in environments hosting business-critical applications.

For Accor’s IT teams, the result is tangible: fewer incidents, fewer performance issues, less unpredictable behaviour, and ultimately more time available for higher-value tasks.

On a human level, the relationship with Nutanix plays a decisive role. The partnership has grown over time, with genuine proximity, consistent support, and a deep understanding of Accor’s technical and contractual challenges.

“If I had to summarize Nutanix’s contribution in three words, I would say: stability, performance, scalability”, he concluded. “And above all, a true partnership: Nutanix is there when we need them, not just at renewal time.”
