### About
Mainflux is modern [highly-secured](https://github.com/mainflux/mainflux-auth-server) open source and patent-free IoT cloud platform written in Go.

It allows device, user and application connections over various network protocols, like HTTP, MQTT, WebSocket and CoAP, making a seamless bridge between them. It is used as the IoT middleware for building complex IoT solutions.

![Cloud Architecture](https://github.com/Mainflux/mainflux-doc/blob/master/img/cloudArchMonochrome.jpg)

Mainflux is built with <3 by Mainflux [team](MAINTAINERS) and community contributors.

### Security
For professional deployments Mainflux is usually combined with [Mainflux Authentication and Authorization Server](https://github.com/mainflux/mainflux-auth-server) which adds fine-grained security based on customizable API keys.

Mainflux Auth Server also provides user accounts and device and application access control with simple customizable scheme based on scoped JWTs.

### Install/Deploy
Mainflux uses [MongoDB](https://www.mongodb.com/), so insure that it is installed on your system. You will also need MQTT broker running on default port 1883 - for example [Mosquitto](https://mosquitto.org/).

> N.B. Professional Mainflux deployments use [EMQTTD](https://github.com/mainflux/emqttd-docker) - massively scalable MQTT broker written in Erlang. The way it is used can be seen from [docker-compose.yml](docker-compose.yml)

Installing Mainflux is trivial [`go get`](https://golang.org/cmd/go/):
```bash
go get github.com/mainflux/mainflux
$GOBIN/mainflux
```

If you are new to Go, more information about setting-up environment and fetching Mainflux code can be found [here](https://github.com/mainflux/mainflux-doc/blob/master/goenv.md).

### Docker
Running Mainflux in a Docker is even easier, as it will launch whole composition of microservices, so you do not have to care about dependencies.

- Clone the repo:
```bash
git clone https://github.com/Mainflux/mainflux.git && cd mainflux
```

- Start the Docker composition:
```bash
docker-compose up
```

This will automatically download Docker images from [Mainflux Docker Hub](https://hub.docker.com/u/mainflux/) and deploy the composition.

### System Architecture
Mainflux IoT cloud is composed of several components, i.e. microservices:
- [Mainflux Core (HTTP API Server and Admin)](https://github.com/mainflux/mainflux)
- [Authentication and Authorization Server](https://github.com/mainflux/mainflux-auth-server)
- [MQTT PUB/SUB Broker (with WebSocket and CoAP support)](https://github.com/mainflux/emqttd-docker)
- Mongo Database
- [Dashflux UI](https://github.com/mainflux/dashflux)

Docker composition that constitues Mainflux IoT infrastructure is defined in the [`docker-compose.yml`](https://github.com/Mainflux/mainflux/blob/master/docker-compose.yml).

### Features
An extensive (and incomplete) list of features includes:
- Responsive and scalable architecture based on a set of [microservices](https://en.wikipedia.org/wiki/Microservices)
- Set of clean APIs: HTTP RESTful, MQTT, WebSocket and CoAP
- SDK - set of client libraries for many HW platforms in several programming languages: C/C++, JavaScript, Go and Python
- Device management and provisioning and OTA FW updates
- Highly secured connections via TLS and DTLS
- Enhanced and fine-grained security via deployment-ready [Mainflux Authentication and Authorization Server](https://github.com/mainflux/mainflux-auth-server) with Access Control scheme based on customizable API keys and scoped JWT
- Easy deployment and high system scalability via [Docker](https://www.docker.com/) images
- Clear project roadmap, extensive development ecosystem and highly skilled developer community
- And many more
