## Update

We recently merged updates to run Heron natively using [Mesos](http://mesos.apache.org/) in [AWS](https://aws.amazon.com/), Mesos/[Aurora](http://aurora.apache.org/) in AWS, and locally on a laptop.  

We also added beta testing for [Apache YARN](https://hadoop.apache.org/docs/r2.7.1/hadoop-yarn/hadoop-yarn-site/YARN.html) support using [Apache REEF](http://reef.apache.org/), in addition to the Simple Linux Utility for Resource Management [(SLURM)](http://slurm.schedmd.com/). 

We are working to add support for [Mesosphere DC/OS](https://dcos.io/) and [Kubernetes](http://kubernetes.io/).  We will continue to post updates as we progress.
