The environment consists of a user interface provided by an applications manager and usually an application programming interface (API) to the applications manager. An operating environment is not a full operating system, but is a form of middleware that rests between the OS and the application. For example, the first version of Microsoft ...
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 ...
The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
Sometimes, the most relevant layer for a specific software is called a computing platform in itself to facilitate the communication, referring to the whole using only one of its attributes – i.e. using a metonymy. For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2]
Likewise, hardware devices such as disks or DVD drives are active entities that a program can interact with via a runtime system. One unique application of a runtime environment is its use within an operating system that only allows it to run. In other words, from boot until power-down, the entire OS is dedicated to only the application(s ...
Remote desktop virtualization implementations operate in a client/server computing environment. Application execution takes place on a remote operating system which communicates with the local client device over a network using a remote display protocol through which the user interacts with applications.
For virtualized desktop environments, user virtualization represents a fundamental change in how the corporate desktop is constructed, delivered and managed. The user’s personality is decoupled from the operating system and applications, managed independently and applied to a desktop as needed without scripting, group policies or use of user profiles – regardless of how the desktop is ...
