Call me Maybe: Chronos
Chronos (the Mesos distributed scheduler) comes out looking pretty crappy here

Cluster-Based Architectures Using Docker and Amazon EC2 Container Service
In this post, we’re going to take a deeper dive into the architectural concepts underlying cluster computing using container management frameworks such as ECS. We will show how these frameworks effectively abstract the low-level resources such as CPU, memory, and storage, allowing for highly efficient usage of the nodes in a compute cluster. Building on some of the concepts detailed in the earlier posts, we will discover why containers are such a good fit for this type of abstraction, and how the Amazon EC2 Container Service fits into the larger ecosystem of cluster management frameworks.

Mesosphere · Docker on Mesos
This is cool. Deploy Docker container images onto a Mesos cluster: key point, in the description of the Redis example: 'there’s no need to install Redis or its supporting libraries on your Mesos hosts.'

Introducing Chronos: A Replacement for Cron
A distributed, fault-tolerant "cron" is something which comes up frequently -- it makes for a great fault-tolerance building block. This one sounds like it's too closely tied into Mesos, though (IMO).
Chronos is our replacement for cron. It is a distributed and fault-tolerant scheduler which runs on top of Mesos. It's a framework and supports custom mesos executors as well as the default command executor. Thus by default, Chronos executes SH (on most systems BASH) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the mesos slaves on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchroneous callbacks to notify Chronos of job completion or failures.
