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]
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
Proxmox Virtual Environment (Proxmox VE or PVE) is a virtualization platform designed for the provisioning of hyper-converged infrastructure. Proxmox allows deployment and management of virtual machines and containers. [7] [8] It is based on a modified Debian LTS kernel. [9]
In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. [1] Screenshot of one virtualization environment. Virtualization began in the 1960s with IBM CP/CMS. [1]
Each container is a separate entity, and behaves largely as a physical server would. Each has its own: Files System libraries, applications, virtualized /proc and /sys, virtualized locks, etc. Users and groups Each container has its own root user, as well as other users and groups. Process tree A container only sees its own processes (starting ...
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .
The main classes of Docker objects are images, containers, and services. [23] A Docker container is a standardized, encapsulated environment that runs applications. [26] A container is managed using the Docker API or CLI. [23] It is a process created from an image. A Docker image is a read-only template used to build containers.
A virtual environment is a networked application that allows a user to interact with both the computing environment and the work of other users. Email, chat, and web-based document sharing applications are all examples of virtual environments. Simply put, it is a networked common operating space.
