I integrated open telemetry into serverless AWS Lambda as part of a proof-of-concept (POC) project. We developed a Lambda layer for open telemetry, which produced telemetry graphs that allowed us to monitor data flow and interactions within the architecture. Open telemetry revealed important details about data points and connections, which were beneficial for failure analysis. However, the associated costs were quite high, making it impractical for production use. Consequently, we decided to send consumption logs to Kafka, which proved to be a simpler and more cost-effective solution. While open telemetry provided valuable insights, we chose alternative methods due to budget constraints.
