Below are the differences in multiple criteria that show why Docker has advantages over virtual machines.
Memory Space : In terms of memory, Docker occupies lesser space than a virtual machine.
Boot-up Time : Docker has a shorter boot-up time than a virtual machine.
Performance : Docker containers show better performance as they are hosted in a single Docker engine, whereas, performance is unstable if multiple virtual machines are run.
Scaling : Docker is easy to scale up compared to virtual machines.
Efficiency : The efficiency of docker is higher, which is an advantage over virtual machines.
Portability : Docker doesn’t have the same cross-platform compatibility issues with porting as virtual machines do.
Space Allocation : Data volumes can be shared and used repeatedly across multiple containers in Docker, unlike virtual machines that cannot share data volumes.
