The success of Docker is close related to DevOps paradigm, sure. Whatever invention that almost everyone accepts as the facto standard means that the invention is good. Developers have never been good friends of systems, databases, networks, firewalls, clusters, balancers,… for me that’s the key. Now developers are happy.
Anyway, almost always, hangover comes after the night party. Is Docker strong enough to run secure an reliable in production?
The more robust Docker will become, the less light, quick, fun and easy will be, and after all, Solaris Zones is out of there since more than 10 years ago…
