3. An Introduction to DC/OS
v1.11

4. DC/OS High Level Architecture
Cluster Manager
Container OrchestratorA Batch Job Scheduler
• DC/OS is a platform for running distributed containerized software,
like apps, jobs, and services.

5. DC/OS Core: Apache Mesos
Image source: Anton Kirillov, Data processing platforms architectures
Apache Mesos is a cluster
manager which abstracts CPU,
memory, storage, and other
compute resources away from
machines (physical or virtual), and
enables fault-tolerant and elastic
distributed systems to easily be
built and run effectively.

25. 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

26. WSO2 DC/OS Resources

27. First Generation of WSO2 DC/OS
Resources (DC/OS v1.7)
• DC/OS resources of 14 WSO2 products/components:
– https://github.com/wso2/mesos-artifacts

28. Second Generation of WSO2 DC/OS
Resources (DC/OS v1.11)
• DC/OS resources for IS deployment patterns 1 & 2 are
implemented:
– https://github.com/wso2/dcos-is
• DC/OS resources for API-M deployment pattern 1 are
currently being implemented
– https://github.com/wso2/dcos-apim/
– Need to add HA for API-M and API-M Analytics
• Need to update DC/OS Membership Scheme to support
DC/OS v1.11:
