Earlier this week Mesosphere launched Marathon, an open source framework based on Mesos for long-running services:
https://github.com/mesosphere/marathon Marathon was built by the same team that did Chronos, with other contribs coming in now. Also, a couple articles just came out about Mesos, including discussion of Marathon use cases: http://strata.oreilly.com/2013/09/running-batch-and-long-running-highly-available-service-jobs-on-the-same-cluster.html http://gigaom.com/2013/09/04/new-open-source-tech-marathon-wants-to-make-your-data-center-run-like-googles/ Twitter has Aurora coming out -- similarly, for managing fault-tolerant services atop Mesos. Glad to see this space heating up!
