Too Long; Didn't Read
In the beginning of the web, there was a ‘developer’ who wrote the ‘code’. This code would get built and then chucked over the wall to the ‘operations’ folks. They — you know, operated the website that their company made money from. Sys admins, data center people, database admins (I forgot they still exist — hi DBAs!). There were strict protocols on managing releases. Testing was a pain, and it took a long time to ship anything.
