Explore serverless observability in AWS through this 36-minute conference talk from GOTO EDA Day 2022. Discover how to effectively monitor Lambda functions, handle failures, and leverage CloudWatch for optimal application performance. Learn about best practices, automation techniques, and the open-source tool SLIC Watch for streamlined dashboard and alarm setup. Gain insights into error tracing, capacity inspection, and making sense of alerts in serverless environments. Understand the importance of observability testing, native AWS tools, and alternatives outside the AWS ecosystem. Perfect for developers and architects looking to enhance their serverless monitoring and troubleshooting skills.
