It is a software solution to run local compute, messaging, data caching, syncing, and have Machine Learning inference capabilities.
Using AWS Greengrass connected devices (as in IOT for example) can run AWS Lamda functions, keep device data in sync and communicate with other devices securely in the Internet's unconnected scenario. This way using local compute you can interact with local resources, intermittent connections and updates with air updates.
AWS Greengrass involves both local resources as well as AWS. The development uses the same programming languages.
AWS Greengrass can:
- filter data so that only necessary data is transacted to the cloud
- Authenticates and encrypts device data at all points of connection(using AWS IoT Core)
Here is a video how AWS Greengrass works.
Benefits:
- Respond to Local events in Near Real-time
- Operate off line
- Reduce the Cost of running I0T Applications
- Simplified Device Programming with AWS Lamda
Nokia's Multi-access Edge Computing (MEC) together with AWS Greengrass addresses the Enterprise use-case such as off shore Oil Exploration
