Docker doesn’t create a whole operating system like a virtual machine. Dockerĭocker is an open-source container technology and it is quite popular because it makes it easier to create, run and deploy applications in a self-contained environment. It runs on the operating system of the host machine and shares libraries and binaries when possible and only separates the absolutely necessary resources. The container has the necessary properties like code, runtime, system libraries and tools to keep the application separate from outside environment. This makes it less resource hungry and lightweight.

ContainersĬontainers create virtualization on the operating system level and they work as an executable software package that isolates applications from its surrounding environment. KVM, Red Hat Enterprise Virtualization (RHEV), XenServer, Microsoft Hyper-V and VMware vSphere / ESXi are the prominent players. There are a lot of hypervisors available in the market. Modern virtual machines run on hypervisors that are the software, firmware or hardware responsible for the creation and execution of VMs. The VM technology can be used with VMware, Oracle Virtual Box and many more.
However its the host machine that provides the necessary physical resources but the virtualized environment works as an independent machine with its own BIOS, CPU, storage, and network adapters.
Virtual MachineĪ virtual machine (VM) is more like a physical computer which comes with its own complete operating system and resource allocation. So let’s understand briefly about some of the difference more between VM and Container.
