For more information:


We recently merged updates to run Heron natively using Mesos in AWS, Mesos/Aurora in AWS, and locally on a laptop.

We also added beta testing for Apache YARN support using Apache REEF, in addition to the Simple Linux Utility for Resource Management (SLURM).

We are working to add support for Mesosphere DC/OS and Kubernetes. We will continue to post updates as we progress.
