    Episode 200: Java & Spring AI Are Winning the Enterprise AI Race — with James Ward & Josh Long
    Mar 18 2026
    It's a milestone — episode 200! And to mark the occasion, we're doing something we've never done before: hosting two guests at the same time. James Ward (Principal Developer Advocate at AWS) and Josh Long (Spring Developer Advocate at Broadcom, Java Champion, and host of 'A Bootiful Podcast') join Romain for a wide-ranging conversation about why Java and Spring AI are becoming the go-to stack for enterprise AI development. We kick off with Spring AI's rapid evolution — from its 1.0 GA release to the just-released 2.0.0-M3 milestone — and why it's far more than an LLM wrapper. James and Josh break down how Spring AI provides clean abstractions across 20+ models and vector stores, with type-safe, compile-time validation that prevents the kind of string-typo failures that plague dynamically typed AI code in production. The numbers back it up: an Azul study found that 62% of surveyed companies are building AI solutions on Java and the JVM. James and Josh explain why — enterprise teams need security, observability, and scalability baked in, not bolted on. We dive into the Agent Skills open standard from Anthropic and James's SkillsJars project for packaging and distributing agent skills via Maven Central. We also cover Spring AI's official Java MCP SDK (now at 1.0) and how MCP and Agent Skills complement each other for building capable, composable agents. The performance story is striking: Java MCP SDK benchmarks show 0.835ms latency versus Python's 26.45ms, 1.5M+ requests per second versus 280K, and 28% CPU utilization versus 94% — with even better numbers using GraalVM native images. Josh and James also walk us through Embabel, the new JVM-based agentic framework from Spring creator Rod Johnson, featuring goal-oriented and utility-based planners with type-safe workflow definitions built on Spring AI foundations. We close with a look at running Spring AI agents on AWS Bedrock AgentCore — memory, browser support, code interpreter, and serverless containers for agentic workloads.

  • AWS Hero Linda Mohamed: Juggling Cloud, Community & Agentic AI

    AWS Hero Linda Mohamed: Juggling Cloud, Community & Agentic AI
    Mar 11 2026
    Some guests make you want to close your laptop and go build something. Linda Mohamed is one of them. In this episode, Romain sits down with Linda — AWS Community Hero, User Group Leader, Chairwoman of the AWS Community DACH Association, and independent cloud consultant based in Vienna. Linda started as a Java developer in on-premises enterprise environments. Her first AWS touch point? Building an Alexa skill for a smart home product — discovering Lambda almost by accident, and never looking back. Today she's building multi-agent AI systems, running an AI-powered video pipeline with five media customers, and doing it all while being one of the most energetic and generous contributors in the AWS community. Discover Linda's journey from Java developer in telecom to cloud and AI consultant, conference-driven development as a forcing function to ship, building Otto — a multi-agent Slack bot using Crew AI, LoRA fine-tuning, and Amazon Bedrock Agent Core Runtime. Learn about the AI-powered video analysis pipeline she built to solve her own problem and ended up selling to five media customers, vibe coding vs spec-driven development and when each makes sense, and why Clean Code principles still apply when designing agent architectures.

  • Evolving Lambda: from ephemeral compute to durable execution

    Evolving Lambda: from ephemeral compute to durable execution
    Mar 4 2026
    In this episode, Romain sits down with Michael Gasch, Product Manager at AWS for Lambda Durable Functions, to explore one of the most exciting launches in the Serverless space in recent years. Michael shares the full story: from the early days of Lambda and the evolution of the serverless developer experience, to the challenges developers face when building multi-step, stateful workflows — and how Durable Functions addresses them natively within Lambda. Discover the evolution of AWS Serverless and why last year was 'the year of Lambda', key launches including IDE integrations, Lambda Managed Instances, and Lambda Tenant Isolation. Learn what Lambda Durable Functions are and what they are not, the checkpoint-replay model and how it enables resilient, long-running executions, and wait patterns including simple wait, wait for callback, and wait for condition. Explore real-world use cases: distributed transactions, LLM inference orchestration, ECS task coordination, and human-in-the-loop workflows. Michael shares unexpected feedback from customers about architectural simplification, how coding agents like Kiro dramatically accelerate writing Durable Functions, and when to choose Durable Functions vs. Step Functions vs. SQS/SNS. Plus, what's coming next: more regions, and the Java SDK (now available!).
