## What it is
DC/OS is an open-source distributed operating system built on the Apache Mesos kernel that manages clusters of machines, providing container orchestration, scheduling, service discovery, and networking from a single interface. The project reached end of life in October 2021 and is no longer maintained.

## Use cases
- run containers and microservices across a cluster
- manage big data and fast data pipelines in production
- schedule distributed workloads on-premises or in the cloud
- install data services like Kafka or Spark with one click
- run Kubernetes alongside other workloads on a shared cluster
- aggregate resources of many machines into one platform

## When to choose
- you are maintaining a legacy DC/OS cluster or studying historical cluster orchestration
- you need a Mesos-based platform with Marathon scheduling in an existing deployment

## When to avoid
- starting any new project - the project is end-of-life with no support since October 2021
- you want an actively maintained orchestrator - use Kubernetes instead
- you need community support, security patches, or new features

## Facets
- artifact type: infra-config
- maturity: abandoned
- function: container-orchestration, scheduling, service-discovery, deployment, microservices, package-manager, networking, monitoring
- domain: cloud-computing, microservices, big-data, self-hosted
