The practice of encapsulating software applications away from the OS is known as?

The practice of encapsulating software applications away from the operating system is best described as application virtualization. This method allows applications to run in an isolated environment, making them independent from the underlying operating system. This can lead to improved compatibility, easier management, and enhanced security, as applications can be moved or updated without needing to modify the host OS.

With application virtualization, the applications are packaged along with the necessary dependencies, enabling them to function as if they are installed directly on the OS, yet they operate in a separate space. This technique is particularly beneficial in enterprise environments, allowing for streamlined application deployments and testing.

Containerization, while similar, specifically involves packaging an application and its dependencies in a lightweight, portable container. Although it achieves some of the same goals, such as isolating applications from the host OS, it typically focuses more on running applications in a consistent environment across different infrastructures.

Server consolidation refers to the practice of reducing the number of physical servers by running multiple virtual servers on a single physical server. This is more about optimizing resource usage in data centers rather than encapsulating applications.

Function isolation involves separating different functions or services within applications, which can help protect against vulnerabilities, but it does not encompass the overall isolation of applications from the OS in the same
