Automate Lambda Monitoring and Error Reporting through in-house AWS services

This guide shows how to use AWS CloudWatch and SNS to proactively monitor and receive notifications for errors in a micro-service application. It involves creating an SNS topic and subscribing to it, creating an IAM role and Lambda function, and adding a CloudWatch log trigger with a filter pattern to the Lambda. The guide provides CLI commands and pre-configured files to make the process easy to follow.
