DC/OS can be installed on any cluster of physical or virtual machines.
You can enable authentication in your datacenter with DC/OS oauth. Authentication is managed through the DC/OS web interface. The Admin Router enforces access control.
DC/OS cluster nodes generate logs that contain diagnostic and status information for DC/OS core components and DC/OS services.
Monitoring the health of all the pieces that make up DC/OS is vital to datacenter operators and for troubleshoooting hard-to-diagnose bugs. You can monitor the health of your cluster components from the DC/OS UI component health page. The component health page displays information from the system health API, which monitors the core DC/OS components.
DC/OS applications lose their state when they terminate and are relaunched. In some contexts, for instance, if your application uses MySQL, or if you are using a stateful service like Kafka or Cassandra, you’ll want your application to preserve its state. Configure Mesos mount disk resources to enable users to create tasks that can be restarted without data loss. Learn how to create stateful applications.
The DC/OS virtual network feature is an out-of-the-box virtual networking solution that provides an ip-per-container for Mesos and Docker containers alike. The DC/OS virtual network uses CNI (Container Network Interface) for the Mesos Containerizer and Docker libnetwork for the Docker Containerizer.
