How to send data from AWS IoT Greengrass to Cloud?

The statistical data collected from the edge devices can be published to AWS IoT Core service. AWS IoT Core supports the MQTT, HTTPS, MQTT over WSS, and LoRaWAN.
Console : https://console.aws.amazon.com/iot/
Catalog: https://aws.amazon.com/iot-core/

Refer to the workshop below which demonstrates the MQTT publisher implementation using AWS IoT Greengrass.
With MQTT topics, IoT clients identify the messages they publish by giving the messages topic names.

Once messages are collected into AWS IoT Core, You can integrate data in real-time with other AWS services such as Kinesis, DynamoDB, S3, CloudWatch, and so on.

• Greengrass IPC lets you publish/subscribe messages to AWS IoT Core. You can find few examples : https://docs.aws.amazon.com/greengrass/v2/developerguide/ipc-iot-core-mqtt.html#ipc-operation-publishtoiotcore

• Regarding Streaming from notebook camera, you can use gstreamer library on your notebook and create a RTSP : https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/examples-gstreamer-plugin.html
