## Overview
|
|
|
|
|
|
|
|
Go Micro provides the core requirements for distributed systems development including RPC and Event driven communication.
|
|
|
|
The **micro** philosophy is sane defaults with a pluggable architecture. We provide defaults to get you started quickly
|
|
|
|
but everything can be easily swapped out.

## Features

Go Micro abstracts away the details of distributed systems. Here are the main features.
|
2016-07-03 04:49:13 +03:00
|
|
|
|
2018-12-02 16:23:46 +03:00
|
|
|
- **Service Discovery** - Automatic service registration and name resolution. Service discovery is at the core of micro service
|
2019-01-16 16:12:21 +03:00
|
|
|
development. When service A needs to speak to service B it needs the location of that service. The default discovery mechanism is
|
2019-11-07 01:04:02 +03:00
|
|
|
multicast DNS (mdns), a zeroconf system.
|
2018-12-02 16:23:46 +03:00
|
|
|
|
|
|
|
- **Load Balancing** - Client side load balancing built on service discovery. Once we have the addresses of any number of instances
|
|
|
|
of a service we now need a way to decide which node to route to. We use random hashed load balancing to provide even distribution
|
|
|
|
across the services and retry a different node if there's a problem.
|
|
|
|
|
|
|
|
- **Message Encoding** - Dynamic message encoding based on content-type. The client and server will use codecs along with content-type
|
|
|
|
to seamlessly encode and decode Go types for you. Any variety of messages could be encoded and sent from different clients. The client
|
2018-12-26 15:03:08 +03:00
|
|
|
and server handle this by default. This includes protobuf and json by default.

|
|
|
|
2019-02-09 15:25:34 +03:00
|
|
|
- **Request/Response** - RPC based request/response with support for bidirectional streaming. We provide an abstraction for synchronous
|
2018-12-02 16:23:46 +03:00
|
|
|
communication. A request made to a service will be automatically resolved, load balanced, dialled and streamed. The default
|
|
|
|
transport is http/1.1 or http2 when tls is enabled.
|
|
|
|
|
|
|
|
- **Async Messaging** - PubSub is built in as a first class citizen for asynchronous communication and event driven architectures.
|
|
|
|
Event notifications are a core pattern in micro service development. The default messaging is point-to-point http/1.1 or http2 when tls
|
|
|
|
is enabled.

|
|
|
- **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. Find plugins in
