  2. Docker (software) - Wikipedia

    en.wikipedia.org/wiki/Docker_(software)

    Docker clients connect to registries to download ("pull") images for use or upload ("push") images that they have built. Registries can be public or private. The main public registry is Docker Hub. Docker Hub is the default registry where Docker looks for images. [23] [27] Docker registries also allow the creation of notifications based on ...

  3. Containerization (computing) - Wikipedia

    en.wikipedia.org/wiki/Containerization_(computing)

    In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor. [1]

  4. Software appliance - Wikipedia

    en.wikipedia.org/wiki/Software_appliance

    A virtual appliance is a virtual machine image designed to run on a specific virtualization platform, while a software appliance is often packaged in more generally applicable image format (e.g., Live CD) that supports installations to physical machines and multiple types of virtual machines. [4] [5] [6]

  5. LXC - Wikipedia

    en.wikipedia.org/wiki/LXC

    It provides operating system-level virtualization through a virtual environment that has its own process and network space, instead of creating a full-fledged virtual machine. LXC relies on the Linux kernel cgroups functionality [8] that was released in version 2.6.24. It also relies on other kinds of namespace isolation functionality, which ...

  6. OpenVZ - Wikipedia

    en.wikipedia.org/wiki/Openvz

    While virtualization technologies such as VMware, Xen and KVM provide full virtualization and can run multiple operating systems and different kernel versions, OpenVZ uses a single Linux kernel and therefore can run only Linux. All OpenVZ containers share the same architecture and kernel version.

  7. Singularity (software) - Wikipedia

    en.wikipedia.org/wiki/Singularity_(software)

    Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. [4]One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world.

  8. Solaris Containers - Wikipedia

    en.wikipedia.org/wiki/Solaris_Containers

    Zones act as completely isolated virtual servers within a single operating system instance. By consolidating multiple sets of application services onto one system and by placing each into isolated virtual server containers, system administrators can reduce cost and provide most of the same protections of separate machines on a single machine.

  9. Virtual machine - Wikipedia

    en.wikipedia.org/wiki/Virtual_machine

    In computing, a virtual machine (VM) is the virtualization or emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two.
