It is easier to change a system or a software development stack than it is to change the habits and preferences of people. People are the biggest friction in adopting new technologies – right up until the moment they are not. And then they are easy. So it is with any technology, and the transition from traditional software change management to open source DevOps tools is no different.
It is ironic, perhaps, that the change comes last to the tools that track the changes. But the move to DevOps is as inevitable as it is desirable, flexible, and valuable.
