+We're excited to announce deeper integration between OpenTelemetry and Lambda functions! This update brings the granular insights of invocations and CloudWatch metrics directly into your Lambda entity instrumented with OpenTelemetry, empowering you to monitor and analyze your serverless functions easily. 
+
+**Lambda Invocations**
+Gain a complete picture of each execution, including details like duration and the triggering event source (API Gateway, DynamoDB, etc.) to analyze your Lambda functions' performance. 
+
+**CloudWatch Metrics Integration**
+CloudWatch metrics are now integrated with OpenTelemetry, to provide valuable insights into your Lambda functions' health. Monitor key metrics like invocation frequency, execution duration, errors, throttling events, concurrent executions, and even dead letter queue failures (if configured). 
+
+By monitoring this comprehensive data set, you can:
+* **Optimize Function Efficiency:**Identify areas for improvement and streamline your Lambda functions for peak performance.
+* **Troubleshoot Issues Quickly:** Pinpoint and resolve problems as soon as they arise, minimizing downtime and ensuring smooth operation.
+* **Proactive Monitoring with CloudWatch Alarms:** Define custom thresholds and configure CloudWatch alarms to receive notifications when critical metrics exceed pre-defined limits, allowing you to proactively manage your serverless applications.
