OS and Sys Admins Did It First - DevOps
A change from manually configuring every server, operating system, and virtual machine to operating a nimble set of infrastructure at scale
1 Server Admin : 100-200 Servers
to
1 Server Admin : 5,000 – 10,000 Servers
CLI + Bash scripts + Reactive configuration

Before and After APIs and Automation
Do you support RFCnnnn?
What is your cost/port?
Do you have my favourite CLI dongle?
Have you fixed that bug in IOS?
Is XYZ feature supported on all platforms in the same way?
Do you have an API for that?
Do you support my DevOpsframework and/or programming language?
Can I configure that via an API?
Have you fixed the bug in that API/Plugin?
Is this API/Plugin available across all platforms consistently?
Thank you.
