# Self-host an Amazon IoT SiteWise Edge gateway with Amazon IoT Greengrass V2
<a name="gw-self-host-gg2"></a>

Set up Amazon IoT SiteWise Edge to collect, process, and visualize data from industrial equipment locally before sending it to the cloud. Self-host using Amazon IoT Greengrass Version 2.

An Amazon IoT SiteWise Edge gateway acts as the intermediary between your industrial equipment and Amazon IoT SiteWise. Running on Amazon IoT Greengrass Version 2, the SiteWise Edge gateway supports data collection and processing on premises.

There are two types of self-hosted gateways:

**MQTT-enabled, V3 gateway**  
The MQTT-enabled, V3 gateway architecture provides improved data ingestion capabilities. It utilizes MQTT protocol for efficient data communication and offers configurable data destinations. These include options for buffered data ingestion using Amazon S3, as well as real-time data ingestion. You can implement path filters to subscribe to specific MQTT topics, enabling targeted data collection. Note that the MQTT-enabled, V3 gateway does not support the Data Processing Pack feature. For more information, see [MQTT-enabled, V3 gateways for Amazon IoT SiteWise Edge](mqtt-enabled-v3-gateway.md).

**Classic streams, V2 gateway**  
The Classic streams, V2 gateway represents the traditional Amazon IoT SiteWise Edge gateway architecture. It is well-suited for existing SiteWise Edge deployments and users accustomed to the established workflow. While the Classic streams, V2 gateway supports the data processing pack, note that data generated by the data processing pack cannot be ingested through Amazon S3. Use the Classic streams, V2 gateway if you need to maintain compatibility with existing deployments or if you require the data processing pack functionality. For more information, see [Classic streams, V2 gateways for Amazon IoT SiteWise Edge](classic-streams-v2-gateway.md).
