 - **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures.

 - **Pluggable Interfaces** - Go Micro makes use of Go interfaces for each distributed system abstraction. Because of this these interfaces
   are pluggable and allows Go Micro to be runtime agnostic. You can plugin any underlying technology.
