Twitter provides some interesting reading on Apache Mesos. Apache Aurora offers:
a service scheduler that runs on top of Mesos, enabling you to run long-running services that take advantage of Mesos’ scalability, fault-tolerance, and resource isolation
O’Reilly’s “Learning Apache Moses” offers a list of a few companies that have Mesos in production: Twitter, Airbnb, HubSpot, MediaCrossing, Sharethrough, Ooyala, Devicescape, iQiyi, OpenTable, CloudPhysics, Xogito, Vimeo.
But Mesos gets more interesting when one considered deployment of services via Docker:
Docker containers provide a consistent, compact and flexible means of packaging application builds. Delivering applications with Docker on Mesos promises a truly elastic, efficient and consistent platform for delivering a range of applications on premises or in the cloud.
