You know, Puppet isn’t a massively bad solution, if you’re managing your own hardware. I’ve done Puppet before. IMO, Chef is better, but Puppet still works reasonably well.

And for that matter, if you’re running your own CI/CD solution, Jenkins isn’t that bad, either.

Also mind that this work was done about a decade ago, and Puppet and Jenkins were newer and shinier tools back then.

Now, if you can operate in the cloud, then I can point you at solutions that I think are better — depending one which cloud you’re in, and what tools are natively available there. But on-premise hasn’t changed all that much in a decade.
