[$] The container orchestrator landscape

Docker and other containerengines can greatly simplify many aspects of deploying a server-sideapplication, but numerous applications consist of more than one container.Managing a group of containers only gets harder as additional applicationsand services are deployed; this has led to the development of a class oftools called container orchestrators. The best-known of these by far is Kubernetes; the history of containerorchestration can be divided into what came before it and what came after.
