Monitor AWS Lambda Provisioned Concurrency metrics with Datadog

AWS has introduced Provisioned Concurrency, a new feature that enhances the resilience of AWS Lambda to cold starts during bursts of network traffic. This feature ensures that functions remain initialized and ready to handle requests in milliseconds, improving user experience and preventing revenue loss due to slow page loads or request timeouts. Datadog has updated its AWS Lambda integration to include Provisioned Concurrency metrics for comprehensive visibility into all Lambda functions. Understanding and optimizing the usage of Provisioned Concurrency is crucial for ensuring optimal performance and cost-efficiency in serverless applications.
