The text discusses the challenges organizations face when migrating legacy web applications to serverless environments like AWS Lambda, which are event-driven and stateless, unlike traditional persistent HTTP servers. The AWS Lambda Web Adapter facilitates this transition by enabling web server-based applications to run on Lambda with minimal changes, allowing organizations to leverage Lambda's scalability and cost advantages. However, this setup can obscure the request life cycle and complicate the connection of logs, traces, and metrics without additional instrumentation. Datadog's integration with the Lambda Web Adapter addresses these challenges by providing full visibility into real-time metrics, traces, and logs from Lambda-hosted web applications. The integration involves including Datadog's Lambda Extension and Web Adapter binary in the Lambda function package and configuring necessary environment variables. This setup allows Datadog to automatically capture telemetry data, enhancing monitoring, performance detection, and troubleshooting capabilities without needing to modify application code. Datadog extends its Serverless Monitoring to include comprehensive insights into web applications running through the Lambda Web Adapter, capturing enhanced metrics like cold start durations and memory usage, and correlating logs with traces and metrics for unified visibility into runtime activity and application errors.
