What is an example of a virtual machine?
A system virtual machine is fully virtualized; it provides a platform for the execution of a complete operating system. Here, multiple VMs can run in parallel on a host system, sharing the physical resources. Some examples are VMWare, VirtualBox, and Parallels.
How do you tell if a machine is a virtual machine?
A virtual machine (VM) is a digital version of a physical computer. Virtual machine software can run programs and operating systems, store data, connect to networks, and do other computing functions, and requires maintenance such as updates and system monitoring.
How do you define a virtual machine?
A virtual machine, commonly shortened to just VM, is no different than any other physical computer like a laptop, smart phone, or server. It has a CPU, memory, disks to store your files, and can connect to the internet if needed.
What is generally a virtual machine?
A VM lets you run a virtual machine on any hardware. Docker lets you run an application on any operating system. It uses isolated user-space instances known as containers. Docker containers have their own file system, dependency structure, processes, and network capabilities.
Is Docker a virtual machine?
Strictly speaking, what it actually represents is the resources of the other virtual machines, since Windows itself is running in a virtual machine under the hypervisor. You may not be explicitly using the hypervisor, but some other features are built on top of the hypervisor.
Is Windows a virtual machine?
Virtual machines (VMs) or guests represent instances of an operating system co-located on a physical machine through the use of a hypervisor. Each VM has its own operating system, memory, and other resources, which are isolated from the other VMs on the same physical computer.

Advantages of Docker Containers
Docker containers are process-isolated and don't require a hardware hypervisor. This means Docker containers are much smaller and require far fewer resources than a VM. Docker is fast.
Why Docker instead of VM?
From what I understand, VMs use hardware virtualization, whereas dockers use software virtualization and therefore have better performance (in a case, lets say, I am running a Dockerized Linux on a Windows machine).

What is VMware vs VM?
Containers have a number of benefits over traditional virtualization methods. As they are more lightweight and portable than VMs, containers support decomposition of a monolith into microservices. Containers are faster to manage and deploy than VMs, which can save time and money with application deployment.
Is there a free virtual machine?
A virtual machine is a packaged operating system that can run on top of a “host” operating system. Virtualization allows the same host to run multiple “guest” operating systems, and easily move virtual machines between hosts. Windows 10 virtualization is managed by Microsoft's own hypervisor, called Hyper-V.

Is a virtual machine a SAAS or IaaS?
Virtualization. Docker engine uses a containerization technology, where the application and its operational components are packed into a container in the host operating system kernel, virtualizing only the application layer. However, Docker may not be as safe as full virtualization.
What is better than a virtual machine?
Containers, while offering some level of isolation, share the host operating system, which can lead to potential security vulnerabilities if not properly managed. So, in terms of isolation, VMs are generally considered to provide better isolation than containers.

Performance. The last main Docker vs VM difference refers to performance: Virtual Machines are more resource-intensive than Docker containers as the virtual machines need to load the entire OS to start. The lightweight architecture of Docker containers is less resource-intensive than virtual machines.
