The AWS Developers Podcast

In this episode of the AWS Developers Podcast, recorded live at the AWS Summit in London, we dive into the world of chaos engineering with guest Simon Hanmer, Principal Consultant at GlobalLogic and AWS Community Builder. Together with Tiffany and Sébastien, we unpack what chaos engineering is, why it matters for resilience in modern cloud architectures, and how AWS customers are adopting these practices today. Simon explains how chaos engineering isn't about breaking things for fun, but about building confidence in how systems behave under stress—just like astronauts or firefighters train for the worst-case scenarios. We discuss AWS Fault Injection Service (FIS), best practices for injecting controlled failures, and how to safely test your assumptions before disaster strikes. Simon shares practical insights from his work with enterprise customers, the evolution of resilience testing from data centers to the cloud, and what’s next for chaos engineering, including integrating into CI/CD pipelines and shifting testing left. If you're curious about how to make your cloud architecture truly resilient—or how Netflix and Amazon do it in production—this is the episode for you.With Simon Hanmer, UK&I Principal Consultant, GlobalLogicChaos EngineeringSimian Army from Netflix (now deprecated)Fault Injection ServiceLocalstackAdrian Hornsby's blog on resilienceThe Amazon builder library

In this episode, Seb and Abram Douglas dive deep into OAuth 2.0 and the challenges of machine-to-machine (M2M) authentication. They unpack the security trade-offs between API keys and the client credentials grant flow, explaining how Amazon Cognito can generate time-bound access tokens and use Lambda triggers for token customization. The conversation highlights token claims, secure verification methods, and how API Gateway integrates with Cognito for simplified authorization. Seb and Abram also explore fine-grained access control using Amazon Verified Permissions and outline best practices like securing secrets with AWS Secrets Manager, rotating client credentials, and enabling AWS WAF. Finally, they look ahead to the role of AI agents in secure M2M communication, stressing the importance of user consent, identity propagation, and robust token management in future architectures.With Abrom Douglas, Solution Architect, Amazon CognitoEmpower AI agents with user context using Amazon CognitoCognito User PoolClient Credentials Flow, OAUth 2 specification

In this episode of the AWS Developers Podcast, we explore the first major step in Cancer Research UK’s broader move to serverless: the migration of their payment systems. While this application was the first to make the shift, it paved the way for many other products and services that have since followed suit—marking a significant milestone in their serverless journey. Our guests, Ellie Wintram and Swetha Podduturi, walk us through the motivations behind the migration, the architecture decisions that shaped it, and the key AWS services that made it possible. They share how technologies like AWS Lambda and DynamoDB enabled cost savings of up to 94%, why TypeScript was the right fit for their microservices, and how observability and load testing were central to building trust in the new system. Whether you're planning a migration or curious about serverless best practices in production, this episode is packed with technical insights and practical lessons from the field.With Swetha Podduturi, Software Engineer, Cancer Research UK ; With Ellie Wintram, Software Engineer, Cancer Research UKCancer Research UK

Everton Oliveira and Krzysztof Głuszczyk from Ryanair discuss the airline's ambitious integration of generative AI to meet its goal of 300 million passengers. They highlight the importance of responsible AI, including the establishment of an AI compliance hub amidst regulatory challenges. The duo provides insights into identifying use cases and optimizing processes, balancing innovation with compliance, and the role of cross-functional collaboration. With a commitment to continuous improvement, they share how they evaluate AI responses through both human and automated systems.

Tobie Morgan Hitchcock, Co-founder & CEO of SurrealDB, dives into the groundbreaking world of multi-model databases. He explains how SurrealDB simplifies complexity by separating storage from compute while supporting various data models. Tune in as he discusses the shift from Golang to Rust, the flexibility of schema definitions, and practical use cases for real-time decision-making in the cloud. Plus, hear about the importance of open-source innovation and how SurrealDB stands up to competitors like Postgres and MongoDB.

This week on the AWS Developers Podcast, we sit down with Avi Fenesh to explore the evolution of Redis into Valkey, an open-source alternative born after Redis changed its licensing model. They take a deep dive into Valkey GLIDE, a new client library designed to provide a seamless developer experience, making it easier to connect to Valkey with zero configuration. The conversation covers the architectural decisions behind Valkey GLIDE, its implementation in Rust for performance and safety, and how it supports multiple programming languages. Avi explains how the AWS-led project has grown into a thriving community-driven effort, placing developer experience, security, and scalability at its core. Topics include API design, Unix domain socket security, and how Valkey GLIDE handles complex scenarios like topology changes in clustered environments. Whether you’re building with Redis, experimenting with Rust, or just curious about the future of open source in-memory database solutions, this episode offers insights into how Valkey GLIDE is reshaping client-library development with a strong focus on community and usability.With Avi Fenesh, Software Development Engineer, AWSValkeyValkey GLIDEForeign functions interfaceUnix domain socket

In this episode of the AWS Developers Podcast, we dive into the different ways to deploy large language models (LLMs) on AWS. From self-managed deployments on EC2 to fully managed services like SageMaker and Bedrock, we break down the pros and cons of each approach. Whether you're optimizing for compliance, cost, or time-to-market, we explore the trade-offs between flexibility and simplicity. You'll hear practical insights into instance selection, infrastructure management, model sizing, and prototyping strategies.
