In the example code for this blog, I also added an AWS api gateway so we can trigger the Lambda using a public URL. That is out of scope for this blog, but you can visit the source code and check it out.

To receive the messages from the queue, we will use the sqs-consumer library. The service will receive messages describing newly created orders. After some processing, it will change the order status in the table to ‘completed’.

  Create your own Lambda Layer in each OTel language using this starter code. Add the Lambda Layer to your Lamdba Function to get tracing with OpenTelemetry.

  

You don’t have to create an opentelemetry configuration file such as this for each of your lambdas. In fact, you shouldn’t. In AWS, you can use Lambda Layers. You can define the OpenTelemetry tracing piece of code as a Lambda layer and use it in any Lambda you want. Furthermore, OpenTelemetry went ahead and implemented this opentelemetry-lambda layer for us. All we need to do is use it with our config.
