Leverage Azure Cosmos DB for time-series for IoT Applications
summary
Shows that Azure Cosmos DB can be a one‑stop IoT store: device, tenant, entitlement, alarms and high‑volume telemetry all live in one design. Demo pushes many devices through IoT Hub -> serverless function -> Cosmos DB with single‑digit ms writes, using partition key = device+month to avoid 20 GB logical limits, autoscale Request Units to absorb bursts, and change feed plus TTL to stream recent hot data to Data Lake Gen2 for cold storage and long‑range queries.
