IoT Backend with Redis, S3 and Node.js

Redis is a perfect solution for IoT backends, especially when significant amounts of data need to be ingested from multiple devices and be made available via APIs.

This paper outlines a solution that supports collecting and exposing energy readings from smart meters with an extremely low TCO and minimal data maintenance, using Redis, Node,js and AWS S3.

The signifcant advantage of such a solution over relational databases accrues from the substantially higher performance and simplicity of deployment offered by in-memory Redis.
