Datacenter Operating System (known also as DC/OS) is an open-source operating system and distributed system built upon the Apache Mesos project.[3] It was developed by Mesosphere and announced in April 2016.[4]
Origins
The term datacenter operating system was promoted in the paper The Datacenter Needs an Operating System,[5] published at the University of California, Berkeley. In the paper Zaharia et al. describe four areas of functionality that a datacenter OS should provide:
- Resource sharing
- Data sharing
- Programming abstractions
- Debugging and monitoring
The paper promoted the Mesos project for resource sharing among frameworks on a shared compute cluster.
Architecture
Datacenter Operating System categorizes components as being in user space or kernel space.[6] Kernel space includes the Mesos master and agents while user space includes various system components of Datacenter Operating System. These components include (among others):[7]
- Admin Router, an internal load balancer
- Cosmos, an internal packaging API service
- Exhibitor, a Java supervisor system for ZooKeeper
- Marathon, an Apache Mesos framework for container orchestration
- Mesos-DNS, an internal DNS service
History
On 19 April 2016, Mesosphere open-sourced Datacenter Operating System.[4] At the launch, Autodesk announced that they were able to reduce running AWS instances by 66% using DC/OS.[8]
