# sitewhere/sitewhere

SiteWhere is an industrial strength open-source application enablement platform for the Internet of Things (IoT). It provides a multi-tenant microservice-based infrastructure that includes device/asset management, data ingestion, big-data storage, and integration through a modern, scalable architecture.  SiteWhere provides REST APIs for all system functionality.  SiteWhere provides SDKs for many common device platforms including Android, iOS, Arduino, and any Java-capable platform such as Raspberry Pi rapidly accelerating the speed of innovation.

## What it is
SiteWhere is an open-source, multi-tenant IoT application enablement platform built on Java/Spring microservices, offering device and asset management, data ingestion, big-data storage, and REST APIs. It ships SDKs for Android, iOS, Arduino, and Java-capable devices like Raspberry Pi, and runs on Kafka, Zookeeper, MongoDB, and Kubernetes with Helm charts.

## Use cases
- manage a fleet of IoT devices with assignments and device types
- ingest sensor telemetry over MQTT at scale
- build a multi-tenant IoT platform with REST APIs
- connect Arduino or Raspberry Pi devices to a backend
- store and analyze IoT event data in big-data stores
- deploy an IoT microservice stack on Kubernetes

## When to choose
- you already run SiteWhere and need reference material for an existing deployment or fork
- you need a Java-based IoT platform whose domain model matches your existing integration
- you want to study a mature microservice-based IoT architecture

## When to avoid
- you are starting a new IoT project - the project is unmaintained since 2021 and its successor DeviceChain is the active path
- you want a lightweight stack - SiteWhere requires Kafka, Zookeeper, MongoDB, and a service mesh
- you need timely bug fixes or security patches
