The Datadog CloudFormation macro is an integration that helps organizations manage serverless observability data from their Lambda functions, without writing boilerplate code. It enables engineering teams to grow with Datadog by automatically collecting metrics, traces, and logs from Lambda functions, streamlining how they monitor their applications. The macro can be used with AWS SAM and AWS CDK tools to build serverless applications in a clean and coherent way, reducing friction in developing and monitoring applications. With the macro, developers can explicitly manage trace, log, and enhanced metric collection using infrastructure as code, and configure alerts that automatically notify them of issues degrading their user experience. The integration provides a comprehensive view of all serverless functions running in an environment, allowing users to drill down into specific functions and correlate traces with related logs and metrics for greater context around errors or slowdowns.
