21. DC/OS Reference Architecture
• Container registry for container image management
• Marathon applications for container orchestration
• Marathon API or Mesos DNS API for service discovery
• Service endpoints for internal routing
• Marathon application labels for load balancer configuration
• Marathon load balancer for external routing
• Persistent volumes for sharing configurations, extensions
and runtime artifacts

22. WSO2 API-M DC/OS Resources
• DC/OS resources for API-M deployment pattern 1 are
currently being implemented
– https://github.com/wso2/dcos-apim/
• Expected to complete by Q2, 2018
• Will be releasing DC/OS resources for all API-M
deployment patterns iteratively
