In this talk we’ll use a serverless application that uses various AWS resources. We'll explore how Amazon DevOps Guru recognizes operational issues and anomalies, such as increased latency and error rates. We will also explore DevOps Guru "Proactive Insights" which recognizes configurational anti-patterns, such as missing failure destination on Kinesis Data Streams or DLQ on SQS or over-provisioning of AWS services like DynamoDB tables.
