Very Simple Microservices architecture in Go

Simple microservices project in GO for M7024E @ LTU

The microservices are:

• API Gateway
• Collector
• Datastore

For simplicity the API Gateway also serves the static main-page with the Javascript embedded to call the API GW endpoints.

The API GW

It uses port 7000 and handles the below endpoints

* /index.html                [GET]
* /api/sensors               [GET]
* /api/sensors/{sensor-id}   [GET]

An optional ?number=X URL parameter can be passsed to limit the number of datapoints returned.

The DataStore

It uses port 7001 and handles the below endpoints

* /api/sensors               [GET/POST]
* /api/sensors/{sensor-id}   [GET]

The data for now is stored in a simple SQLite3 lcoal database.

The Collector

It does not need a port because it is simply implementing a functionality as described on the architecture. It has two hard-coded timers defined. One defines how often to refresh the SSiO auth token and another defines how often to poll and store new Data from SSiO.

Plans for improvement:

• migrate away from SQLite3 to PostgreSQL
• fully implement it via docker containers
• deploy in a docker swarm
