And we have HYPE all over the place: cloud services, frameworks, programming languages, tools, application architectures, etc.
And to my eyes DevOps is another hyped thing. Not only that, many jobs require you to be "certified" in a cloud service provider (a la Cisco like in the 90's) or on some particular tools (Kubernetes?).
Then we re-discover that the OLD way was really good, that actually there was no need for something that over-engineered, and we go back and start doing things the simple OLD way. After some time, the cycle re-starts.
What is DevOps anyways? I don't know, but today it seems that is a word associated to fancy cloud services and tools to deploy applications, way way different from the savvy system administrator from the 90's & 2000's that knew lots core concepts as: DNS, LDAP, SNMP, HTTP (Apache), SMTP, NFS, iptables, etc.
If I had to hire someone for today tasks I'd probably stick to the 90's knowledgeable system administrator.
