In this comprehensive AWS re:Invent 2022 session, Julian Wood explores best practices for advanced serverless developers. He covers a wide range of topics including serverless as a mindset, event-driven architectures, state management, service-full serverless, Lambda optimizations, and the software development lifecycle. Wood emphasizes the importance of using managed services, infrastructure as code, and observability tools to build efficient, scalable, and cost-effective serverless applications. He provides practical tips on optimizing Lambda functions, handling cold starts, and leveraging AWS services like EventBridge, Step Functions, and SAM for improved development workflows. The talk is packed with valuable insights for both experienced serverless developers and those looking to deepen their understanding of serverless architectures on AWS.
