Challenge

Spotify has grown to over 200 million monthly active users across the world. After being an early adopter of microservices and Docker, Spotify had containerized microservices running across its fleet of VMs with a homegrown container orchestration system called Helios.

Helios is a Docker orchestration platform for deploying and managing containers across an entire fleet of servers. Helios provides an HTTP API as well as a command-line client to interact with servers running your containers. ~ https://github.com/spotify/helios
