The AWS Serverless Application Repository is a new service that allows developers to publish and deploy serverless applications on AWS, using the Serverless Application Model (SAM) template. Datadog has included two serverless applications in its launch: an RDS enhanced integration and a VPC Flow Log integration, making it easier for customers to monitor high-resolution OS-level metrics from RDS instances and capture IP traffic flowing to and from their virtual private cloud's network interfaces. These integrations provide valuable insights into AWS environment performance and security, allowing developers to quickly deploy serverless applications on AWS without manual setup or configuration steps. The integrations can be found in the Serverless Application Repository, and Datadog offers a 14-day free trial for new users to try out its serverless applications.
