Many of us think about DevOps in terms of "Guinness Book of Records". We admire tools which can create new vm from image in 30 seconds or create hundred of servers in an hour. After this we see, that real life is not so fascinating as in DevOps presentations. Legacy technologies, lack of credibitlity in organization ("everything works fine as always") and lack of funds can kill every initiative. I want to show, how to design, create and implement "low cost" CI/CD process which influenced and changed my organization. How to go through the way from scepticism to "you cannot stop this" state.
