Micro is a microservice ecosystem simplifying distributed development. It provides the fundamental building blocks for developing distributed applications. The micro documentation is here as a guide for adopting Micro.

Introduction

Micro is a microservice ecosystem. It’s goal is to simplify distributed systems development.

Technology is rapidly evolving. Cloud computing now gives us almost unlimited scale, however leveraging that scale with existing tools is still difficult. Micro attempts to solve this problem with a developer first focus.

At the core, micro is simple and accessible enough that anyone can easily get started writing microservices. As you scale to hundreds of services, micro will provide the fundamental tools required to manage a microservice environment.

Overview

The main piece of software provided is Micro, a microservice toolkit.

The toolkit is composed of the following components:

  • Go Micro - A pluggable RPC framework for writing microservices in Go. It provides libraries for service discovery, client side load balancing, encoding, synchronous and asynchronous communication.

  • API - An API Gateway that serves HTTP and routes requests to appropriate micro services. It acts as a single entry point and can either be used as a reverse proxy or translate HTTP requests to RPC.

  • Sidecar - A language agnostic RPC proxy with all the features of go-micro as HTTP endpoints. While Go is a great language for building microservices, you may also want to use other languages, so the Sidecar provides a way to integrate your other apps into the Micro world.

  • Web - A web dashboard and reverse proxy for micro web applications. We believe that web apps should be built as microservices and therefore treated as a first class citizen in a microservice world. It behaves much the like the API reverse proxy but also includes support for web sockets.

  • CLI - A straight forward command line interface to interact with your micro services. It also allows you to leverage the Sidecar as a proxy where you may not want to directly connect to the service registry.

  • Bot - A Hubot style bot that sits inside your microservices platform and can be interacted with via Slack, HipChat, XMPP, etc. It provides the features of the CLI via messaging. Additional commands can be added to automate common ops tasks.

Note: Go-micro is a standalone library and can be used independent of the rest of the toolkit.

Runtime

The toolkit is pluggable and runtime agnostic. Run micro on your laptop, in docker, using kubernetes, AWS and so on.
