IoT Core
Definition
AWS managed service for securely connecting IoT devices with device authentication, message routing, and shadow state management at massive scale.
Use Cases
- Volkswagen Group: Connected vehicle telemetry and fleet data ingestion for analytics and operational insights — Volkswagen’s cloud platform has used AWS IoT services to securely ingest vehicle signals and route messages into downstream AWS analytics and storage services for processing and insights. (Improved ability to collect and analyze vehicle data at scale, enabling faster insights for connected-vehicle features and operations.)
- Carrier: Connected HVAC monitoring and remote service for commercial and residential equipment — Carrier has used AWS IoT services to connect devices, ingest operational telemetry, and integrate with cloud applications for monitoring, diagnostics, and remote management workflows. (Better visibility into equipment performance and more proactive maintenance/service capabilities through cloud-connected monitoring.)
- Philips Hue (Signify): Smart lighting control and device-to-cloud connectivity for home automation scenarios — Smart lighting ecosystems commonly use managed IoT connectivity patterns (secure device identity, message routing, and state synchronization) to connect hubs/devices to cloud services and mobile apps. (Reliable remote control experiences and scalable device connectivity supporting large consumer device fleets.)
Provider Equivalents
- AWS: AWS IoT Core
- Azure: Azure IoT Hub
- GCP: No direct equivalent (Google Cloud IoT Core was retired in 2023); common alternatives include Pub/Sub + partner IoT platforms
- OCI: OCI Streaming (often paired with OCI Functions/Events for ingestion patterns); no direct first-party IoT device hub equivalent
Frequently Asked Questions
- What's the difference between AWS IoT Core and AWS IoT Greengrass?
- AWS IoT Core is the cloud service that securely connects devices and routes their messages to other AWS services. AWS IoT Greengrass runs on edge devices (like gateways) so you can process data locally, run Lambda functions/containers at the edge, and keep devices working even with intermittent internet. Many solutions use both: Greengrass at the edge and IoT Core in the cloud.
- When should I use AWS IoT Core?
- Use AWS IoT Core when you need secure, scalable device connectivity to AWS with features like mutual TLS authentication, fine-grained authorization policies, MQTT/HTTP messaging, rules-based routing to services (for example, Lambda, S3, DynamoDB, Kinesis), and device shadows to track desired/reported state. It’s a good fit for fleets of devices such as sensors, industrial equipment, smart home products, and connected vehicles.
- How much does AWS IoT Core cost?
- Pricing is usage-based. Common cost drivers include the number of messages exchanged (publish/receive), connectivity and protocol usage, rules engine actions (routing messages to other services), and features you enable such as Device Shadow operations. You also pay separately for downstream services you route data into (for example, Lambda, DynamoDB, S3, Kinesis). Exact rates vary by region and feature, so estimate with the AWS Pricing page and the AWS Pricing Calculator.
