Common Questions

Frequently Asked

Protocol selection depends on device constraints, data frequency, and network environment. MQTT is ideal for reliable telemetry over TCP, CoAP suits extremely constrained devices over UDP, BLE works for short-range local communication, and WebSockets enable real-time browser dashboards. We evaluate power budget, bandwidth, and latency requirements to recommend the optimal protocol stack.

We implement defense-in-depth security: X.509 certificates for device authentication, TLS encryption for data in transit, secure boot for firmware integrity, and role-based access control for cloud APIs. Device credentials are rotated automatically, and we use AWS IoT Device Defender for continuous security auditing and anomaly detection.

Our architecture uses managed cloud IoT services (AWS IoT Core, Azure IoT Hub) that auto-scale to millions of concurrent connections. Time-series databases use hypertable partitioning for efficient writes, Kinesis handles burst ingestion, and edge computing offloads processing to reduce cloud load. We design for horizontal scaling from day one.

Over-the-air updates use signed firmware images distributed through AWS IoT Jobs. Devices check for updates on a configurable schedule, download delta patches to minimize bandwidth, verify cryptographic signatures, and apply updates with automatic rollback on failure. Fleet-wide rollouts use canary deployments to catch issues early.
