The overview topics help you get started and learn the DC/OS fundamentals.

DC/OS is a distributed operating system based on the Apache Mesos distributed systems kernel. It enables the management of multiple machines as if they were a single computer. It automates resource management, schedules process placement, facilitates inter-process communication, and simplifies the installation and management of distributed services. Its included web interface and available command-line interface (CLI) facilitate remote management and monitoring of the cluster and its services.
