Docker vs Virtual Machine
Factors |
Docker |
Virtual Machine |
Booting |
Boots in seconds |
Boots in minutes |
Availability |
Pre-built docker containers are easily available |
Ready-made VMs are difficult to find |
Resource |
Less resource usage |
More resource usage |
Storage |
Containers are lightweight (KBs/MBs) |
VMs are of few GBs |
Operating System |
Each container can share OS |
Each VM has a separate OS |
Movability |
Containers are destroyed and re-created instead of moving |
VMs can move to new hosts easily |
Runs on |
Dockers make use of the execution engine. |
VMs make use of the hypervisor. |
Usage |
Docker has a complex operation medium conforming of both third-party and docker-managed tools. |
Tools are simpler to work with and easy to use. |
Working |
Containers stop working with the execution of the “stop command” |
VMs are always in the working running state |
Controlling |
Images can be interpretation controlled; they have an original registry called Docker Hub. |
VM doesn’t have a central hub; they aren’t interpretation controlled |
Memory Management |
It is more memory efficient. | It is less memory efficient. |
Isolation |
It has no provision for an isolation system which is why it is highly prone to problems. | It has an efficient isolation mechanism. |
Time |
It is easy to deploy and takes less time compared to Virtual Machines. | It is a lengthy process. Hence, it takes lots of time for deployment. |
Ease-of-Use |
It is a little difficult to use because of the complex usage mechanism. | It is easy to use. |
Docker or Virtual Machines – Which is a Better Choice?
When businesses were looking to transform their operations through the use of advanced technology in the past but were constrained by a variety of software, cloud, and on-premises infrastructure, they developed two solutions, namely Docker and Virtual Machines, which were introduced to address these business problems with a container platform. These software platforms make the process of deploying applications and microservices simpler. Let’s now discover how they differ from one another. In this composition, we’ll compare the differences and give our keenness to help you decide between the two. Before we get started agitating about Docker vs VM differences, let’s first explain the basics.
