"DevOps" doesn't mean shit. It's a bullshit term define by who is using it. That team is in charge of kubernetes, and automated application deployment stuff, so they are the team ensures developers can push to production quickly. Which, now that I google it- it's exactly what the "official" definition is.
Well, in our case, dev ops means the developer is also responsible for setting up the CloudFormation template to create any resources, CodeBuild to create packages and CodePipeline or Octopus Deploy to deploy code.
