Which of the following will you use to run multiple applications on servers with a variety of OS Docker virtual machine?

VMs are a better choice for running apps that require all of the operating system’s resources and functionality when you need to run multiple applications on servers, or have a wide variety of operating systems to manage.

Can an application can be made available to run on multiple operating systems?

For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native.

What is Docker vs VM?

In Docker, the containers running share the host OS kernel. A Virtual Machine, on the other hand, is not based on container technology. They are made up of user space plus kernel space of an operating system. Under VMs, server hardware is virtualized.

True, there are other LXC-based container implementations as CoreOS, now Red Hat’s, Rkt, or Canonical’s LXD, but they aren’t so much competitors as they are LXC refinements. That said, you can run Docker containers on essentially any operating system or cloud.
