Gee, how hard is to find SE experts in that particular combination of available ops tools? While in AWS every AWS certified engineer would speak the same language, the DIY approach surely suffers from the lack of "one way" to do things. Change Flux with Argo for example (assuming the post is talking about that Flex and no another tool with the same name), and you have a almost completely different gitops workflow. How do they manage to settle with a specific set of tools?
