In 2009 John Allspaw and Paul Hammond delivered the session “10 deploys per day – Dev & ops cooperation at Flickr.” In forty six minutes they changed the way millions of people would think about the software delivery process for years to come. It didn’t have a name yet, but DevOps was born. DevOps folk preached about the cloud, automation, rapid delivery and any database technology that wasn’t relational… In 2013 Kenny Gorman declared “The DBA is Dead”. For the record, I don’t believe that, but a lot of people do. What is certain is that the world of IT is changing, and the traditional DBA role, and most other data roles, are changing with it. I’m going to explain what DevOps is, where it came from, and its implications for SQL Server. We’ll cover the human and technical basics of database DevOps – and I’m going to discuss some changes that data folk need to make.
