Tools for better Observability in NodeJS Serverless IoT Applications
Observability is crucial for successfully operating large IoT fleets. IoT incorporates different components, including hardware, network, on-device software, and cloud. Devices operate under unreliable conditions and constraints, and need to be monitored remotely. Cloud applications become complex and costly, as they are built to handle device activity at scale. Answering questions such as:
-    Do I have a problem in my IoT application?
-    Where is the problem?
-    What is causing the problem?
-    How much of my fleet is affected?
-    Is my code expensive to run and if yes, how can I fix that? ,
can be challenging. Logging, monitoring and tracing are fundamental observability pillars. However, they are often viewed as non-functionals in IoT applications, and can fall off the radar, or are not standardized during development.

This session will show how to leverage Open Source tools, such as AWS Lambda PowerTools, in a fully functional Serverless IoT application, to ease adoption of best practices for modern application development, and integrate services such as Amazon X-Ray, Amazon CloudWatch and AWS IoT Core features, to achieve end-to-end observability.
