Processing data at the edge with Greengrass and Lambda

Greengrass is yet another recent offering in the space of IoT provided by AWS. In simpler terms, Greengrass is an extension of AWS's own IoT service, and it is specifically designed to extend AWS cloud capabilities to local IoT devices, thus making it possible for them to collect and analyze data closer to the source of information. This is made possible by enabling developers to write and execute serverless code. More specifically, developers who use AWS Greengrass can author serverless code using AWS Lambda either on the cloud or on the device itself and conveniently deploy it for the local execution of applications. Here is a representational architecture of Greengrass depicting the Greengrass Core SDK interconnecting various devices with the AWS Cloud:

The AWS Greengrass Core software primarily consists of:

• A message manager that routes messages between devices, Lambda functions, and AWS IoT. The pub/sub message manager can intelligently...
