One love is a web-based application designed to make managing multiple hosts easier.
It uses Ansible roles which are shared via Galaxy hosting providers APIs and Docker Compose to make a powerful interface which controls all the aspects of the cloud infrastructure.
The main idea behind One Love is to automate the process of seting-up and configuring different host machines on different host providers.
You will be able to group multiple hosts together, and apply certain roles to the every group member therefor making the management of large number of machines a lot easier.
