There are plenty of Fortune 500 companies using CFEngine as well. I'm consulting for a Fortune 10 company using it at massive scale. However its role in a container-centric role will be reduced -- it'll run on the infrastructure hosts but not inside immutable containers.
Phoenix servers. See http://martinfowler.com/bliki/ImmutableServer.html Personally, I believe this is a non-confront of the complexity inherent in modern systems. It's a cop out! You're just saying, we don't need to know the details of the configuration to troubleshoot a problem, we'll just nuke it from orbit and create a new instance. But if you don't UNDERSTAND what went wrong, how can you control the situation well enough to fix it? (This is just not my client, I'm talking about the industry trend.)
Thanks for the info. I absolutely agree with you there. It may have a place with fast-evolving, short-lived or highly distributed technologies, but it's not conducive to solving problems - it just enables to avoid them when they're not serious enough.
