AWS Greengrass
AWS Greengrass is an Internet of Things (IoT) platform from Amazon Web Services that extends AWS cloud capabilities to edge devices, enabling local compute, messaging, data caching, and machine learning inference. It allows devices to run AWS Lambda functions, Docker containers, and process data locally even when disconnected from the cloud, syncing when connectivity is restored. This enables real-time decision-making at the edge while maintaining cloud integration for management and analytics.
Developers should use AWS Greengrass when building IoT applications that require low-latency processing, offline operation, or reduced cloud dependency, such as industrial automation, smart agriculture, or remote monitoring systems. It's particularly valuable for scenarios where bandwidth is limited, data privacy is critical, or real-time responses are needed without cloud round-trips, as it processes data locally on devices like gateways or embedded systems.
