VM (Virtual Machines) |
Docker |
Boot-Time |
VM boots in a few minutes. |
Docker takes a few seconds to boot. |
Runs on |
A virtual machine uses a hypervisor. |
Dockers use an execution engine. |
Memory Efficiency |
It is less efficient because it requires the whole operating system to be loaded before beginning the surface. |
No space will be required for virtualization, so less memory. |
Isolation |
Interference possibility will be minimum because of its isolation mechanism. |
Dockers are prone to adversities. No provisions for many isolation systems. |
Deployment |
VM contains lengthy deployment because it isolated instances are liable for execution. |
Docker contains easy deployment because of an individual image. It is containerized and can be applied beyond each platform. |
Usage |
A virtual machine has tools that are simpler and easy-to-use to implement. |
Docker has a convoluted usage mechanism. It consists of docker managed tools and third party both. |
OS support |
All virtual machines have an isolated OS. |
All the containers can distribute OS. |
Storage |
It requires a few GBs. |
Its container is lightweight (MBs/KBs). |
Availability |
Ready-made virtual machines are available but complex to find. |
Pre-built containers of dockers are available. |
Resource Usage |
More usage of resources. |
Less usage of resources. |
Creation Time |
Creating a virtual machine will take a longer time relatively. |
The container of the docker can be made in seconds. |
