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]
Virtual environment software refers to any software, program or system that implements, manages and controls multiple virtual environment instances (self definition). [1] The software is installed within an organization's existing IT infrastructure and controlled from within the organization itself. From a central interface, the software ...
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.
Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video game console emulators , are designed to also emulate (or "virtually imitate") different system architectures, thus allowing execution of software applications and operating systems ...
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.
It is a container hypervisor providing an API to manage LXC containers. [14] The LXD project was started in 2015 and was sponsored from the start by Canonical Ltd. , the company behind Ubuntu . On 4 July 2023, the LinuxContainers project announced that Canonical had decided to take over the LXD project but a fork called Incus was made.
Vagrant is written in Ruby, but it can be used in projects written in other programming languages such as PHP, Python, Java, C#, and JavaScript. [7] [8] Since version 1.6, Vagrant natively supports Docker containers, which in some cases can serve as a substitute for a fully virtualized operating system. [9]
libvirt is a C library with bindings in other languages, notably in Python, [4] Perl, [5] OCaml, [6] Ruby, [7] Java, [8] JavaScript (via Node.js) [9] and PHP. [ 10 ] libvirt for these programming languages is composed of wrappers around another class/package called libvirtmod. libvirtmod's implementation is closely associated with its ...
