> 6. Freedom to choose the right tech: This is true, but as they say having all these extra technologies comes with a lot of extra dev training, dev hiring and ops costs. Maybe it would have been better to use a 'second best' technology that the team already has rather than the best technology that it doesn't, once those costs are accounted for. A variation of this pushed me to implement a couple parts of an application as micro-services even though I wanted to stick with a monolith. I wanted to use existing open-source packages written in languages other than the primary one that I had chosen for my monolith. It's really a shame that a cross-language, in-process ABI like COM didn't catch on outside of Windows.
