3. Light Weight Virtualization (Docker) Vs Heavy
Weight Virtualization (Virtual Box)
Virtual Box Docker
Created machine are called VM Created machines are called containers
Virtual Machines are created using iso Containers are created using docker images
Size of iso is 100MB to 4 GB
(ubuntu 16.04 server iso 829 MB )
Size of docker image is 1 MB to 200MB.
(alpine image is roughly 3 MB, docker
ubuntu image is 130MB )
In 1 GB RAM spare for creating virtual
machine, then we will be able to create 1
VM or maximum 2.
In 1 GB RAM, we can create hundreds of
containers using docker.
Boot time 35 sec Boot time <1 sec
Storage 10 GB Storage 104 KB
RAM 1 GB RAM 568 KB
VM installation time 21 min Container creation time 19.4 sec
