I had to implement a 2nd deploy for a QA environment, and my first question to the infrastructure team was “won’t this be costly is there a better way to handle this?” They shrugged off the cost and said they would optimize my deploy once I was done with the initial implementation. 6 months later their optimization was to undo all the work not because it wasn’t a good implementation but because it revealed how much non-optimization had went into the QA environment before I even touched it. A lot of cost is probably due to the “we just taped these two things together” strategy for lower environments.
