Dockerisation of server code with auto scalingBy Skylab Vanga

What is DockerDocker is an open-source project that automates the

deployment of applications inside software containers. It provides a additional layer of abstraction and automation of OS level virtualization on Linux.

Provide a uniformed wrapper around a software package: «Build, Ship and Run Any App, Anywhere.

Analogous to shipping containers: The container is always the same, regardless of the contents and thus fits all modes of transport

Docker vs. Virtual Machine

Containers are isolated, but share OS and, Where appropriate, bins/libraries.

VM: You have a container image that is 1GB in size. If you wanted to use a Full VM, you would need to have 1GB times x number of VMs you want.

Docker: With LXC (Linux Container) you can share the bulk of the 1GB, It means that if you have 1000 containers you still might only have a little over 1GB of space for the containers OS, assuming they are all running the same OS image.
