Docker container architecture

Docker is one of the most popular application containerization technologies these days. So why do we want to use Docker if there are other container options available? Because collaboration and contribution are key in the era of open source, and Docker has made many different things that other technologies have not been able to in this area.

For example, Docker partnered with other container developers such as Red Hat, Google, and Canonical to jointly work on its components. Docker also contributed it's software container format and runtime to the Linux Foundation's open container project. Docker has made containers very easy to learn about and use.
