This document discusses using Docker containers with the Mesos cluster manager. Mesos provides a uniform computing platform and reduces costs by allowing containers to be run across a cluster of machines. Using Docker with Mesos allows containers to be horizontally scaled across the cluster while still being able to run other workloads. Service discovery when using Docker on Mesos is still evolving, with solutions based on DNS and Mesos events.

2. One big computer

3. Scaling

4. PaaS, data processing, scheduling, data storage, ….

5. Benefits
• Provides a uniform computing platform
• Reduces operational costs and complexity
• Empowers development teams
• Lessens vendor lock-in

6. Architecture

7. WooRank
• In-house Platform as a Service
• Marathon
• Docker
• HAProxy

8. Docker on Mesos
• Built-in support for deploying Docker
containers on the cluster
• Get the benefits of both Docker and Mesos
• Horizontally scaling containers
• Still able to run “non-Docker” computations

9. Service Discovery
• Still in flux
• Solutions based on DNS
• Solutions based on Mesos events
