Series – Part 2: Serverless Architecture – a practical implementation: IoT Device data collection, processing and user interface.

In part one of this series I briefly discussed the purpose of the application to be built and reviewed the IoT local controller & gateway pattern I’ve deployed. To recap, I have a series of IP cameras deployed and configured to send (via FTP) images and videos to a central controller (RaspberryPI 3 Model B). The controller processes those files as they arrive and pushes them to Amazon S3. The code for the controller process can be found on GitHub.

In this post we will move on to the serverless processing of the videos when they arrive in S3.

Serverless architectures are getting a lot of attention lately – and for good reason. I won’t rehash the definition of┬áthe architecture because Mike Roberts did a fine (and exhaustive) job over at MartinFowler.com.

However, practical illustrations of patterns and implementations are exceptionally hard to find. This series of posts will attempt to close that gap by providing both the purpose, design and implementation of a complete serverless application on Amazon Web Services.

Part 1 – The setup…

Every application needs a reason to exist – so before we dive into the patterns and implementation we should first discuss the purpose of the application.

Nest wants how much for cloud storage and playback?

I have 14 security cameras deployed, each captures video and still images when motion is detected. These videos and images are stored on premises – but getting them to “the cloud” is a must have – after all if someone breaks in and takes the drive they are stored on all the evidence is gone.

If I were to swap all of the cameras out for Nest cameras cloud storage and playback would cost $2250/year – clearly this can be done cheaper… so…
