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 ...
This creates a so-called protocol overhead as the additional data does not contribute to the intrinsic meaning of the message. [5] [6] In telephony, number dialing and call set-up time are overheads. In two-way (but half-duplex) radios, the use of "over" and other signaling needed to avoid collisions is an overhead.
Objects: Docker objects are various entities used to assemble an application in Docker. The main classes of Docker objects are images, containers, and services. [22] A Docker container is a standardized, encapsulated environment that runs applications. [25] A container is managed using the Docker API or CLI. [22]
The company, which was purchased by Cisco earlier this year for $3.7 billion, wants to help customers using Docker containers pinpoint performance issues. The problem with containers is that there ...
Docker, Inc. is an American technology company that develops productivity tools built around Docker, which automates the deployment of code inside software containers. [1] [2] Major commercial products of the company are Docker Hub, a central repository of containers, and Docker Desktop, a GUI application for Windows and Mac to manage containers.
Zones induce a very low overhead on CPU and memory. Most types of zones share the global zone's virtual address space. A zone can be assigned to a resource pool (processor set plus scheduling class) to guarantee certain usage, can be capped at a fixed compute capacity ("capped CPU") or can be given shares via fair-share scheduling.

XNU ("X is Not Unix") is the computer operating system (OS) kernel developed at Apple Inc. since December 1996 for use in the Mac OS X (now macOS) operating system and released as free and open-source software as part of the Darwin OS, which, in addition to being the basis for macOS, is also the basis for Apple TV Software, iOS, iPadOS, watchOS, visionOS, and tvOS.
The term user space (or userland) refers to all code that runs outside the operating system's kernel. [2] User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc.
