Crosser + UNS - How does it fit?

Understand how Crosser can be used to power your Unified Namespace.

Crosser as Azure Container Service

Understand how to run the Crosser Node as an Azure Container Service (ACS)

Invoke messages from external apps/systems

You can trigger flows externally using HTTP or MQTT by sending messages to the Node’s internal HTTP server or MQTT broker.

Use local files to buffer data and overcome connectivity issues

For unstable connections, store data locally and upload or stream it later to services like Azure IoT Hub or Kafka.

Use environment settings to configure HTTP and MQTT Service

Crosser Node supports encryption and authentication for its MQTT Broker and HTTP Server, configurable via local files or environment variables on both Windows and Docker.

The Parquet Writer Module

The Parquet Writer module creates compressed files from arrays for storage in cloud services like AWS or Azure. It auto-detects schema and types but allows overrides for inconsistent data.

Use Data Generator to ingest lists

The Data Generator module can be used to generate some sample data to simulate input from external systems. This is helpful if you want to build a flow with a known message structure on the input side but without having access to that system right now.

Delayed startup processing

Combine Interval and Delay modules to create one-off triggers at any time.
