Services

Micro Services provide additional functionality via external third party services.

Overview

Go Micro provides core abstractions for building distributed systems which are likely direct dependencies on locally hosted infrastructure. In the case of external services such as sending email, sms, etc we leave this up to the user. Yet they are becoming more core to all forms of distributed systems development beyond infrastructure.

This directory serves as guidance for accessing external Micro services managed and hosted by m3o.com and powered by Micro.
