Reusable real world Micro services.

Overview

Micro services provide the fundamental building blocks for any products, apps or services. They can be used in isolation or combined to create powerful distributed systems. The services are intended to be consumed by each other using RPC and from the external world through an API.

Rationale

Read more about the reason for Micro Services in this blog post.

Interfaces

Every service starts with a protobuf interface definition, which is a standard used by Google and everyone else now that gRPC is so dominant. The idea is to define the API in protobuf, code generate and implement the handlers for it. The services can be called by other services on the platform using those code generated clients or an API Gateway, which Micro provides. External calls via the API use the same format but with HTTP/JSON endpoints.

Usage

Run a service from source

micro run github.com/micro/services/helloworld

To call a service from another

import "github.com/micro/services/helloworld/proto"

Call it from the api

curl http://localhost:8080/helloworld

From the command line

micro helloworld call

Hosting

Micro Services are hosted on the M3O platform as serverless building blocks.

M3O converts protobuf to openapi specs and generates clients for the hosted services.

Find the source for M3O in https://github.com/m3o/m3o.
