The performance for Docker is really good but consider when a single host running multiple containers. But when it comes to a highly distributed environment, like let’s say 100’s of hosts running 1000’s of containers, docker needs some orchestration to manage the load balancing, communication, ensure availability and all. “KUBERNETES” and “DOCKER SWARM” are the solutions to your question. If you want to learn Docker I would suggest you learn it and I am mentioning a Docker Training Course which you can take up to learn more about it. You can also watch the Docker video tutorial which will give you all the insights about it. .
