I just noticed I was recognized as a friend of the tree in a weekly meeting by the rust team. It came during my documentation sprint during IDA Summer of Code and I discovered it now, only two and a half month later. Still a very pleasant surprise!

Ok, so I have to first preface this whole blog post by a few things:
I really struggle with the term microservices. I can't put my finger on exactly why. Maybe because the term is hopelessly ill-defined, maybe because it's gotten picked up by the hype train.
