About Virtuozzo

Virtuozzo is a provider of infrastructure software for AI and the cloud, helping cloud service providers, SaaS companies, and enterprises build and operate efficient, scalable infrastructure. We combine an optimised operating system with orchestration, management, automation, and protection to deliver mainframe-like efficiency, performance, reliability, versatility, and security—while reducing overall cost and complexity.
Our Virtuozzo Infrastructure System (V/IS) brings together compute, storage, and networking to support traditional applications, cloud-native workloads, and AI services. We help organisations modernise their infrastructure, make better use of their hardware, and bring new cloud- and GPU-powered services to market on their own infrastructure and under their own brand.
Our technology serves more than 100,000 companies in over 100 countries. With deep engineering roots, we pioneered container-based virtualisation and continue to contribute to foundational open-source projects, including OpenVZ, the Linux kernel, Kubernetes, CRIU, KVM, and OpenStack.
