Explore the hidden complexities and failure patterns within serverless architectures in this 44-minute conference talk from AWS re:Invent 2025. Discover how the apparent simplicity of serverless systems masks the inherent challenges of distributed computing, and learn practical strategies for building resilient applications that can gracefully handle inevitable failures. Examine real-world examples using AWS Lambda and Amazon Kinesis to understand common pitfalls and their solutions. Master the philosophy of failure-driven design, embracing Dr. Werner Vogels' principle that "everything fails, all the time" as a foundation for creating robust serverless systems. Gain insights into distributed system challenges, failure modes, and proven techniques for building fault-tolerant architectures that maintain performance and reliability even when components fail.
