   • [pro] Easy to start with; scales up nicely to disconnected services
   • [pro] Easy horizontal & vertical scaling
   • [con] Requires infrastructure engineering experience
   • [con] Rollout times depends on your build and scaling process

   • [pro] DBaaS offering (Heroku PostgreSQL and more)
   • [con] Cost
   • [pro] Easy access to logs, environment variables
   • [pro] Easy horizontal and vertical scaling
   • [con] Few geographical regions
   • [pro] Easily connect to CI for continuous deployment

10. Docker Cloud
    • You provide computer, Docker provides orchestration
    • [pro] First party offering
    • [pro] You provide compute (via bare metal or cloud providers)
    • [con] You provide compute
    • [pro] Easily connect to CI for continuous deployment
    • [con] Double charge; you pay service and infrastructure costs

11. Docker Swarm
    • First party cluster orchestration
    • [pro] First party offering
    • [pro] You provide compute (via bare metal or cloud providers)
    • [con] Brand new as of 1.12.0; untested
    • [pro] Supports docker client operations
    • [pro] Run on your own infrastructure (cloud or on-prem)

12. Docker Data Center / UCP
    • First party offering
    • [pro] Setups authentication, registry, and swarm out of the box
    • [con] Lags behind the Docker daemon
    • [con] 1.x has issues with multiple availability zones
    • [pro] Run on your own infrastructure (cloud or on-prem)

13. AWS Elastic Container Service
    • Task scheduling for containers
    • [pro] Runs on AWS
    • [con] Not managed; you provision instances and run their agent
    • [con] Low level functionality; rough around the edges
    • [pro] Higher level tools like Empire or Convox smooth out the
    edges

14. Kubernetes / Google Container Engine
    • Container as a Service
    • [pro] Works for all size applications
    • [pro] Run on your own infrastructure (cloud or on-prem)
    • [pro] One-click cloud offering via Google Container Enginer
    • [con] Requires learning an entirely new system
    • [con] Does not support docker clients
    • [con] Containers only
    • [pro] Powerful base to build one (OpenShift runs on Kubernetes)

15. Mesos / DCOS
    • Distributed systems kernel
    • [pro] Works for all size applications
    • [pro] Run on your own infrastructure (cloud or on-prem)
    • [pro] One-click cloud offering via Microsoft Azure
    • [con] Requires learning an entirely new system
    • [con] Does not support docker clients

16. Recommendations
    • Heroku for small and-non distributed applications (really hard to beat
    Heroku’s features)
    • Golden Images or something built on ECS (e.g. Empire/Convox) for small
    distributed applications or you want to run your own infrastructure
    • Kubernetes for container native applications or large distributed
    systems (GKE if don’t want to run infrastructure)
    • Mesos / DCOS if you need to support an entire organization with a mix
    containerized & non-containerized work loads
