VATES edits the VATES Virtual Management Stack : VATES VMS.
VATES VMS is built around XCP-ng, Xen Orchestra and a set of complementary tools. Each component is developed in the open and designed to deliver predictable performance, operational efficiency and full independence from closed ecosystems. All components are open source and maintained by VATES engineering, with a strong community behind them.
VATES VMS seamlessly integrates every layer from the hypervisor, compatible with all x86 servers, to the agentless Web appliance for administration, management, and native XCP-ng backup of virtual machines. At the core of Vates VMS lies the XCP-ng virtualization platform , a powerful engine based on the Xen Project, renowned for its scalability and adherence to high security standards. This robust foundation ensures that VATES VMS can handle the most demanding workloads with ease and reliability. As one of the first contributors to the Xen project, VATES deeply masters Xen.
The Xen Orchestra Appliance provides a powerful interface for management of VMs, containers and native XCP-ng backup tasks, simplifying complex operations. For those seeking hyperconverged infrastructure solutions, XOSTOR is integrated to streamline virtual SAN creation, while XO Proxy ensures efficient backup management in remote office/branch office (ROBO) environments.
Thus VATES offers expertizes in virtualization and its evolutions towards :
-edge computing : ARM, Dom0less, low latency, interference modeling,
-AI accelerators integrations
-highest security : confidential computing, dynamic attestation
-dynamic orchestration : SDN, RBAC, OPA, OTA , AI based

Brief description of my Organisation

VATES is a SME based in Grenoble (French Alps) incorporated in 2012. VATES is an open-source vendor offering a complete virtualization stack (competing with VMware) based on the Xen engine (an open-source project of the Linux Foundation). As one of the earliest contributors to and maintainers of Xen, VATES is the only European open-source vendor to have full control over a virtualization stack, and is therefore able to offer a truly sovereign solution.
Over the past two years, VATES has experienced 200% growth and now has more than 150 employees. 60% of its revenue is generated in the U.S., while R&D is conducted entirely in France. At the end of July, VATES completed a €30 million capital increase with bpifrance Large Venture and IRIS Growth, with the goal of becoming the leading player in open-source virtualization.
