Question

What is the difference between docker and virtual machine?

Answer 1

To understand between Docker and the virtual machine would give you the concept from the most basic level, VMs contain complete operating system AND whatever applications run on it. VM=OS virtualization. More overhead required for the OS, in addition to the application. On the other hand, Docker is an example of application-only virtualization. Less overhead as compared to a true VM. If you wish to work with cloud technologies then I would suggest you must have a certificate in it, so if you want to get the certificate in it then you can take up the following Docker Training Course. I am also mentioning a video tutorial of Docker for your reference which you must watch to learn all the concepts of it.
