Monitoring your AWS Lambda applications with New Relic

AWS Lambda enables the execution of applications without server management, but it requires effective monitoring tools like New Relic to address potential issues that AWS does not cover, such as code quality and configuration problems. While AWS provides insights into billing and compute times, it lacks visibility into code performance, necessitating tools like New Relic for full observability and proactive error detection. New Relic's serverless monitoring wraps around Lambda functions to provide detailed metrics and error information, while synthetic monitoring simulates user flows in production to identify performance issues. This combination allows users to monitor internal function execution and external application performance, ensuring swift identification and resolution of problems before they affect end users.
