Datadog has introduced remote bulk instrumentation of Lambda functions, now in Preview, to help address the challenges of ensuring end-to-end visibility into transaction-level data for production serverless applications. This feature enables organizations to add features like enhanced metrics and distributed tracing to any number of Lambda functions without requiring changes to their CI/CD pipeline or infrastructure-as-code configuration. With remote bulk instrumentation, teams can reduce the time spent modifying deployment pipelines or infrastructure configurations and get visibility into execution-level Lambda traces during critical incidents, even when serverless apps may not have initially been instrumented. The feature allows for granular control over instrumentation, enabling organizations to select which functions to enable bulk instrumentation for and exclude others. This streamlines serverless application management by automatically ensuring AWS Lambda functions are instrumented without needing changes to IaC or code pipelines.
