AWS Greengrass
AWS Greengrass
AWS IoT Greengrass API deploys AWS Lambda and ML models to edge devices (IoT gateways, industrial equipment) for local data processing.
One-click cloud-to-fleet deployment of code/models to thousands of edge devices
Edge devices need sufficient resources (typically ≥512MB RAM)

About this API
Greengrass solves "all-data-to-cloud doesn't work" scenarios — factory floors with 1000 sensors per second produce too much data for network bandwidth; mining/offshore oil rigs have unstable networks; autonomous vehicles need millisecond decisions without cloud roundtrips. Greengrass extends AWS programming model to the edge: write Lambda (or define containers/ML models) in the cloud, Greengrass deploys to edge devices. Devices sync state to cloud every 30s; ML inference runs locally in real-time via Lambda, results uploaded as needed. Greengrass v2 (2020) is a rebuild from v1, more K8s-style component model. Direct competitors: Azure IoT Edge, Google Cloud IoT Edge. Best fit for industrial IoT in manufacturing, energy, agriculture, transportation.
What you can build
- 1Factory edge gateway pre-processes sensor data locally
- 2Devices keep working offline (sync after cloud reconnects)
- 3ML model inference at the edge (image detection, anomaly recognition)
- 4Bulk device fleet management
Strengths & limitations
Strengths
- One-click cloud-to-fleet deployment of code/models to thousands of edge devices
- Supports Lambda, containers, ML models as workloads
- Disconnect tolerance (buffer data locally)
Limitations
- Edge devices need sufficient resources (typically ≥512MB RAM)
- IoT fleet ops is inherently complex (heterogeneous devices)
- Greengrass v2 rebuild is not fully v1-compatible

FAQ
Greengrass v1 vs. v2?+
New projects: v2 (component architecture, more flexible). v1 mainly for legacy users.
Minimum edge device requirements?+
Greengrass v2 nucleus needs ~100MB RAM minimum, but actual workloads (Lambda, ML model) need more.
