# aither

Aither shows an approach how to bootstrap a microservice system in Node.js with [Hemera 5](https://hemerajs.github.io/hemera/) and docker.

You can scale your worker in seconds and because we use NATS as “nervous system" for our distributed system we do not have to worry about service-discovery or load-balancing of hemera-services. We use traefik to load-balancing the api-gateway.

This configuration will setup:

* [Hapi](https://github.com/hapijs/hapi) http server which act as api-gateway to the Hemera services.

* [Microservice](https://github.com/hemerajs/aither/blob/master/worker/index.js) which is responsible to add two numbers.

* [NATS](https://github.com/nats-io/gnatsd) server the underlying messaging system for Hemera.

* [Jaeger](https://github.com/jaegertracing/jaeger) CNCF Jaeger, a Distributed Tracing System.

* [Natsboard](https://github.com/devfacet/natsboard) dashboard to monitoring your NATS system in realtime.

* [Traefik](https://traefik.io/) modern HTTP reverse proxy and load balancer made to deploy microservices with ease.

* [Redis](https://redis.io) in memory cache for Hemera.

## Versions

 * Hapi 17

 * Hemera 5

## Architecture

![aither](https://github.com/hemerajs/aither/blob/master/aither-architecture.png?raw=true)

## Getting started

* Running the system `docker-compose up`

* Start a request against load balancer [OPEN](http://localhost:8182/api/add?a=1&b=10)

* Scale the system `docker-compose scale math-service=5 api=2`

## Dashboards

- Traefik [http://localhost:8181/](http://localhost:8181/)

- NATS Dashboard [http://localhost:3000/](http://localhost:3000/)

- NATS Endpoint [http://localhost:8222/](http://localhost:8222/)

- Jaeger [http://localhost:16686/](http://localhost:16686/)

## Run load test

```bash

npm install -g artillery

artillery run loadtest.yml

```

Print the html artillery report with `artillery report `
