AWS re:Invent 2025 Recap

Send us Fan Mail

A bus-powered hackathon, a $100K prize for a gloriously “useless” app, and keynotes that said AI so many times you could turn it into a supercut—re:Invent 2025 brought energy, irony, and real signals hiding in the noise. We’re joined by AWS Hero Chris Williams to unpack what actually matters: where AI is genuinely useful, where it’s lipstick on a feature, and how builders should adapt without losing the plot.

We dig into the Road to re:Invent hackathon and why the winning project—turning a tiny script into a sprawling multi-repo monster—was the sharpest commentary on over-engineering all week. From there, we break down the AI-first keynotes, new Graviton efficiency gains that could tame power budgets, and the push to own the entire stack from silicon to agents. Kiro’s spec-driven development gets real talk too: amazing for scaffolding, documentation, and repo exploration; risky when you ask a confident hallucination to write production without tests, reviews, or security controls.

The conversation shifts to careers and craft with Werner Vogels’ parting challenge: become a “Renaissance developer.” Learn systems, networking, security, and economics, then layer AI to explore design space faster. If you’re just starting out, don’t begin with prompts—build fundamentals and use AI to shape your learning plan. We wrap with the sleeper headline: first-party multi-cloud connectivity. It’s overdue, it’s serious, and it could reshape how enterprises stitch providers together while raising new questions about SLAs, accountability, and incident response between hyperscalers.

Hit play for a clear-eyed debrief that filters the hype, celebrates real progress, and offers practical guidance for teams shipping in 2025. If this helped you make sense of re:Invent, follow the show, share it with a teammate, and drop your bold prediction for the year ahead.
