At all the places I worked previously in the last ~20 years there was always a sharp separation of development/testing and production environments. I as a developer never had access to any system in production, apart from one place which had a very sophisticated security system in place which could grant you temporary access during deployments. Just think about customer data, and you'll understand why.

So when I hear that someone thinks devops is developers running their own systems in production I always wonder where this is actually possible, let alone whether it is a good idea at all.
