Docker and Virtual Machines- Differences

Docker is a leading container technology which is being adopted by leading software companies, hardware companies and even other businesses.

Due to its light-weight feature, it is loved by all when compared to virtual machines.

Listed below are quick glimpses of major differences between these two server technologies for applications.

 S.No

Docker

Virtual Machines

1

 This is a container based technology which is an open-source.

It is based on hypervisors and not an open-source.

2

 It is light-weight in nature.

VMs are bulk when compared to containers.

3

 Implementation of Docker is difficult.

Virtual machine implementation is easier.

4

 Docker is native to Linux platform and need extra tools to get  deployed in other operating systems.    

Virtual machines can easily be integrated with any operating system.

5

It never uses the entire hardware resource of host system.Instead, it uses just the kernel and in certain cases, the libraries.

This uses the entire hardware resources which increases performance overhead.

6

The same Docker can run on multiple hosts.

This is not possible with VM.

7

The same Docker can run on both cloud and Amazon Web Services.

Virtual Machines do not support AWS. The same VM cannot be used for multiple services.
