For as long as I can remember there have been two widely used definitions of DevOps. One is the one large private corps use where it means developers and operators work close together in the same team. The other one is the cloud thing where DevOps is a role responsible for both development and operations. “You build it, you own it, you run in”, is more or less a scam from the cloud providers cause historically it was very difficult for none-developers to troubleshoot any issues in the cloud. The mantra should be “You build it, you own it, anybody operates it”.
