Session 1 - Observe: Watch Your Sensor Data Move from Edge to Cloud

Every pump, compressor, and sensor is already generating data — the value is in getting the right slice to the right place at the right speed. In this opening session you trace a telemetry reading through its entire journey: simulated field devices publish over MQTT to AWS IoT Core, an IoT Rule fans the stream to Amazon Data Firehose, and Firehose lands it as Apache Iceberg files in S3 for Athena to query. You'll see how fleet provisioning got the devices into IoT Core, subscribe to live telemetry in the console, inspect the Iceberg files on S3, and run your first Athena freshness query. The takeaway: the cheap, limitless archive tier answers in tens of seconds to minutes — and why that makes it the wrong tool for a live operations dashboard, setting up every faster tier that follows.
