The Mesosphere DCOS is a new kind of operating system that spans all of the machines in the datacenter or cloud. It supports today’s developers who are building a new class of applications. These applications no longer fit on a single server, but instead run across a fleet of servers in a datacenter.

The Mesosphere DCOS includes a distributed systems kernel with enterprise-grade security, based on Apache Mesos, and a set of core system services, including an init system (Marathon), cron (Chronos), service discovery (DNS), storage (HDFS), and others.

The Mesosphere DCOS runs containerized workloads at scale, managing resource isolation (including memory, processor, and network) and optimizing resource utilization. It is highly adaptable, employing plug-ins for native Linux containers, Docker containers, and other emerging container systems. Automating standard operations, the Mesosphere DCOS is highly-elastic, highly-available and fault-tolerant.
