  • Docker Swarm
  • Kubernetes
  • Mesos Marathon
  • Amazon ECS
  • Hashicorp Nomad

Container Orchestrators can

  • make a cluster by bringing multiple hosts together
  • schedule containers to run on different hosts
  • help containers running on different hosts to communicate with each other
  • bind containers with storage
  • bind containers of same type into services
