Difference Between Docker Containers and Virtual Machines
The following are the differences between docker containers and Virtual Machines:
Docker Containers | Virtual Machines |
---|---|
Docker Containers contain binaries, libraries, and configuration files along with the application itself. | Virtual Machines (VMs) run on Hypervisors, which allow multiple Virtual Machines to run on a single machine along with its own operating system. |
They don’t contain a guest OS for each container and rely on the underlying OS kernel, which makes the containers lightweight. | Each VM has its own copy of an operating system along with the application and necessary binaries, which makes it significantly larger and it requires more resources. |
Containers share resources with other containers in the same host OS and provide OS-level process isolation. | They provide Hardware-level process isolation and are slow to boot. |
What is Docker?
Docker is a set of Platforms as a service (PaaS) products that use Operating system-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and therefore use fewer resources than a virtual machine.
