Hi, author here. I built Micro based on my experience at Google and Hailo. At Hailo we built a global microservices platform with over 200 bespoke services in production by the time I left. I realised that more and more people were tackling the problem of scale both technically and as an organisation. I felt like the tools were lacking and most companies end up building their own from scratch. Micro was a way of creating a foundation for writing and running distributed systems. It's a pluggable architecture so that the underlying systems can be swapped out based on preference.

Beyond Micro, I'm working on go-platform https://github.com/micro/go-platform which addresses the higher level needs for microservices. Auth, monitoring, metrics, distributed tracing, etc, etc. Again pluggable like Micro. Still in it's infancy.

Cheers Asim
