Today, containers are becoming the default way that people put apps on clouds. In no small part, that's because containers didn't become standardized until libcontainer appeared in 2014. But then Docker headed in its own direction, and others, starting with CoreOS, started splitting off. Fortunately, instead of forking themselves into irrelevance, almost all the containers powers got back on the same page with the Open Container Project (OCP).
"Project Atomic integrates the tools and patterns of container-based application and service deployment with trusted operating system platforms to deliver an end-to-end hosting architecture that's modern, reliable, and secure.
Fedora, CentOS, and Red Hat Enterprise Linux-based Atomic Hosts are now available for download. "
