SUSE Linux Enterprise-class servers. As for Docker, all containers must use the same operating system and kernel. On the other hand, if you just want to make as many server applications as possible run on as few hardware as possible, you may not be interested in running multiple operating system virtual machines. If multiple copies of the same application are exactly what you need, then you will love the

For a long time, however, Docker can only run on a single host, and its ability to deploy, run, and manage across hosts has been widely criticized. The weak cross-host capability leads directly to the tight coup
