Dockers and IoT

Docker is software for containerizing applications. Containers are small and lightweight execution environments that can share the same kernel but can be isolated from each other.

Docker solves many problems in IoT development as it can involve services that have to be written in multiple languages or environments. Also, Docker containers can be lightweight when compared to Virtual Machines. So, it is even possible to run the docker containers on less powerful IoT devices like Raspberry Pi.
