What is DevOps?
You have John, the developer
How about a story?
You have John, the developer
You have Dan, the IT guy.
The Developer
John developed a really cool super duper web application that builds on
Boryana's web scraping app that scrapes web pages for power plans.
He gets commission for any plan sold through his website. He can see his millions
rolling in.
He completes version 1.0 and gives it to Dan, our IT guy to get
working on the production machines.
The IT Guy
What the hell is the requirements? Documentation sucks, I guess I understand,
they want to be first to market.
Requirements?
And so we begin building the server up to serve up the application.
After a hours later, IT guy tries to start the application, doesn't work. Dan goes to talk with John about what might be misconfigured. He gets a few pointers and off Dan goes.
After a week later...
The application is all setup! Time to celebrate right? No. The customers have complained about bugs and feature requests. John needs help so they hire his friend Jim.
Jim spends some time trying to get his computer setup to run John's app. John
says
It works on my computer".
John spent about a week trying to get the development environment on Jim's computer working.
