Bhushan's response indicates that he has experience with a proof-of-concept project using open telemetry in AWS Lambda, but it was not implemented in production due to cost considerations. He mentions the use of a Lambda layer for telemetry and the decision to use consumption logs with Kafka as an alternative. However, the response could be improved by providing more detail on how open telemetry contributed to failure analysis during the POC and discussing the specific insights gained from the telemetry data. Additionally, Bhushan could articulate the cost-benefit analysis that led to the decision not to proceed with production implementation, as demonstrated in the benchmark response.
