Ottomatica slim vs VirtualBox: What are the differences?
Developers describe Ottomatica slim as "Build and run tiny vms from Dockerfiles". It will build a micro-vm from a Dockerfile. It works by building and extracting a rootfs from a Dockerfile, and then merging that filesystem with a small minimal kernel that runs in RAM. On the other hand, VirtualBox is detailed as "Run nearly any operating system on a single machine and to freely switch between OS instances running simultaneously". VirtualBox is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version 2.
Ottomatica slim and VirtualBox can be categorized as "Virtualization Platform" tools.
