  • Spec-Driven Development in Practice: A AWS Hero Journey

    Spec-Driven Development in Practice: A AWS Hero Journey
    Feb 4 2026
    Christian, AWS Hero and Solution Architect at Bundesliga, shares his journey and hard-won lessons from adopting spec-driven development with AI coding assistants at enterprise scale. Learn when to use specs vs vibe coding, how to build effective steering documents, and practical strategies for helping engineering teams transition from traditional development to AI-assisted workflows. Discover the difference between spec-driven and vibe coding approaches, when to use each, and how to build effective steering documents that guide AI assistants. Christian shares enterprise adoption strategies that actually work, including the show-and-tell approach to reduce AI adoption fear, treating AI as a peer teammate, and creating centers of excellence for sharing learnings. We explore custom agents and the single responsibility principle, context engineering over prompt engineering, and dive into exciting re:Invent announcements like Lambda Durable Functions. Whether you're leading engineering teams, exploring AI-assisted development, or looking to optimize your development workflow, this conversation offers practical insights from real-world enterprise implementation.

  • Native Speed, Modern Safety: Swift for Backend Development

    Native Speed, Modern Safety: Swift for Backend Development
    Jan 29 2026
    Join us as we explore Swift beyond iOS with Sebastien Stormacq, AWS Developer Advocate and Swift specialist. Discover why Swift is becoming a compelling choice for server-side development, offering native compilation, memory safety without garbage collection, and modern concurrency features that deliver exceptional performance and cost efficiency. Seb shares how Apple processes billions of daily requests using Swift on AWS infrastructure, achieving 40% better performance and 30% lower costs when migrating services from Java. We dive into the technical advantages that make Swift competitive with traditional backend languages, explore the vibrant server-side ecosystem with frameworks like Vapor and Hummingbird, and discuss practical implementations including serverless architectures on AWS Lambda. Whether you're a Swift developer curious about server-side possibilities, a full-stack developer looking to unify your tech stack, or a backend engineer evaluating language options, this conversation offers practical insights into Swift's capabilities beyond the client.

  • Local Unit Testing for Step Functions

    Local Unit Testing for Step Functions
    Nov 28 2025
    Join us as we dive into the new local unit testing capabilities for AWS Step Functions with Jas Narula, Product Manager from the Step Functions team. We explore how developers can now test their workflows locally using the enhanced Test State API, moving beyond the limitations of the discontinued Step Functions Local container. Jas walks us through the new mocking capabilities, support for advanced states like Map and Parallel, and how this API-based approach gives you the same production runtime for testing. We also discuss the partnership with LocalStack for offline testing, the developer experience with popular testing frameworks like PyTest and Jest, and why this new approach makes Step Functions development more like traditional test-driven development. Whether you're orchestrating Lambda functions, calling Bedrock APIs, or building complex business workflows, this episode shows you how to test with confidence before deploying to the cloud.

  • Building AWS Builder Center: Architecture Lessons from a Large-Scale Community Platform

    Building AWS Builder Center: Architecture Lessons from a Large-Scale Community Platform
    Nov 21 2025
    In this episode, we dive deep into AWS Builder Center, the new community platform designed to consolidate all AWS developer resources into one central hub. Roopal Jain, Software Development Engineer on the Builder Center team, explains how this platform brings together previously scattered AWS community properties like re:Post, Skill Builder, and community.aws into a unified experience for builders. Beyond exploring what Builder Center offers - from articles and events to toolboxes organized by programming language - we take a technical deep dive into how the team built this large-scale web application. Rupal shares the architectural decisions behind their serverless microservices approach, the challenges of integrating Neptune graph database for social features like user following, and creative solutions for handling dual authentication methods in API Gateway. The conversation reveals real-world implementation challenges that many developers face, from VPC networking complexities to service-to-service authentication patterns. We also discuss Builder ID, AWS's new individual identity system, and get a glimpse of what's coming next for the platform.

  • How to not worry about networking on AWS?

    How to not worry about networking on AWS?
    Nov 7 2025
    In this follow-up episode of the AWS Developers Podcast, we continue the conversation with Alex Huides, Principal Network Specialist Solutions Architect at AWS, focusing on Amazon VPC Lattice. We explore how developers can simplify networking concerns while maintaining robust connectivity between applications. Alex explains how VPC Lattice introduces a new boundary concept called service networks, which allows applications to communicate across accounts and VPCs regardless of IP overlap issues. The discussion covers how VPC Lattice abstracts away complex networking details, replacing traditional load balancers while providing secure, private connectivity between services. This episode demonstrates how AWS is removing undifferentiated heavy lifting in networking, making it easier for developers to focus on building applications.
