Datadog APM has introduced native tracing for AWS Lambda functions in Python and Node.js to provide deep visibility into serverless applications. The latest enhancements connect Lambda functions with AWS managed services all in one trace, allowing developers to effectively debug event-driven serverless applications by understanding where an issue occurred and how upstream and downstream services were involved. Datadog APM also tags function spans with additional information about incoming events for quick searching, filtering, and aggregating data when troubleshooting issues. This end-to-end visibility helps developers find and fix problems faster in their serverless applications.
