We made this because we discovered that lots of companies using microservices have independently converged on this type of architecture for load balancing (client-side HAProxy + integrated service discovery component + health checks), but there wasn't a simple, easy-to-setup, end-to-end solution out there. (Our favorite for the record is AirBnb's SmartStack.) We'd love for some feedback and/or PRs and/or GitHub stars!
