Centurion vs Marathon: What are the differences?

Developers describe Centurion as "A mass deployment tool for Docker fleets". A deployment tool for Docker, made by New Relic. Takes containers from a Docker registry and runs them on a fleet of hosts with the correct environment variables, host volume mappings, and port mappings. Supports rolling deployments out of the box, and makes it easy to ship applications to Docker servers. New Relic is using it to run their production infrastructure. On the other hand, Marathon is detailed as "Deploy and manage containers (including Docker) on top of Apache Mesos at scale". Marathon is an Apache Mesos framework for container orchestration. Marathon provides a REST API for starting, stopping, and scaling applications. Marathon is written in Scala and can run in highly-available mode by running multiple copies. The state of running tasks gets stored in the Mesos state abstraction.

Centurion and Marathon can be categorized as "Container" tools.

Centurion and Marathon are both open source tools. It seems that Marathon with 3.87K GitHub stars and 875 forks on GitHub has more adoption than Centurion with 1.72K GitHub stars and 111 GitHub forks.
