Docker vs Virtuozzo: What are the differences?

  1. Architecture: Docker uses a client-server architecture, where the Docker client can communicate with the Docker daemon to build, run, and distribute containers. In contrast, Virtuozzo uses a hypervisor-based architecture with the Virtuozzo hypervisor managing the containers on the host system.

  2. Isolation: Docker containers are isolated with the help of Docker Engine's built-in features, such as namespaces and cgroups, which provide process and file system level isolation. On the other hand, Virtuozzo containers achieve isolation through the Virtuozzo hypervisor, offering a more resource-efficient approach to containerization with greater levels of isolation and security.

  3. Resource Management: Docker containers can utilize resources based on the host system's resources, which can lead to potential resource contention between containers. In comparison, Virtuozzo provides more advanced resource management capabilities, including dynamic adjustment of resources for containers, ensuring better resource utilization and performance isolation.

  4. Kernel Sharing: Docker containers share the host system's kernel, which might lead to dependencies and compatibility issues. In contrast, Virtuozzo containers have their own independent kernel, providing more flexibility in terms of choosing different kernels for various containers running on the same host system.

  5. Performance Overhead: Docker containers have a minimal performance overhead compared to running applications directly on the host system, but Virtuozzo containers offer native performance with near-zero overhead due to the hypervisor-based architecture and advanced optimizations.

  6. Packaging and Deployment: Docker emphasizes ease of packaging and distributing applications using Docker images and the Docker Hub registry. In contrast, Virtuozzo focuses on virtual environment management, offering a comprehensive set of tools for easy deployment and maintenance of containerized applications.

In Summary, Docker and Virtuozzo differ in their architecture, isolation mechanisms, resource management, kernel sharing, performance overhead, and packaging/deployment approaches.

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

      What is Docker?

      The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere

      What is Virtuozzo?

      It is an operating system-level server virtualization solution designed to centralize server management and consolidate workloads, which reduces overhead by reducing the number of physical servers required. Organizations use it for server consolidation, disaster recovery, and server workload agility.
