Datadog APM now connects Python and Node.js Lambda functions to AWS managed services in a single trace, allowing developers to understand where issues occurred and how upstream and downstream services were involved. This enables tracing of event-driven serverless applications across multiple components, including message queues, data streams, notification services, and more. The new feature provides additional tags for function spans, enabling quick search, filtering, and aggregation of data when troubleshooting issues. With this enhancement, Datadog brings distributed traces into the same view as infrastructure metrics and logs, providing detailed context around event-driven architectures. Developers can prioritize fixes more strategically by identifying the scope of an issue and its impact on end users. The new approach to distributed tracing embraces the complexities of modern serverless applications, giving end-to-end visibility into event-driven serverless applications to help find and fix issues faster.
