Building Your Own AI Agent Stack: Lessons from 10 Open Source Projects

I spent the last week falling down a rabbit hole. Not the productive kind where you emerge with a working solution and a sense of accomplishment. The kind where you save ten GitHub repos in a single week and then sit back and realise they’re all telling you the same thing.

Build vs. Buy Just Flipped. Most Teams Haven't Noticed Yet.

The Decision You’ve Been Making on Autopilot Every AWS practitioner has a version of this conversation at least once a quarter. Someone on the team suggests building something custom. Someone else points out there’s a managed service or SaaS product that does it already. The room does the mental maths: engineering time, ongoing maintenance, opportunity cost. Nine times out of ten, you buy.

The Inference Tax Nobody Budgeted For: Why AI Costs Keep Rising

The Number That Should Worry You AWS raised GPU Capacity Block prices by 15% on a Saturday in January. No blog post. No announcement. Just a quiet update to the pricing page that said prices were “scheduled to be updated” without mentioning which direction.

The Real Skill Isn't Coding Anymore. It's Describing What You Want.

You’ve Got the Tools. So Why Are You Still Slow? If you’re building on AWS right now, you have access to more managed services, more abstraction layers, and more AI-assisted tooling than at any point in computing history. CDK, SAM, Amplify, Bedrock, Kiro, Claude Code. The list keeps growing.

AWS STS Identity Provider Claims Validation: Secure OIDC Trust Policies

If you’ve ever written an IAM trust policy for GitHub Actions OIDC federation, you’ve probably done the thing we all did. You set the sub condition to repo:my-org/my-repo:*, told yourself “that’s scoped enough,” and moved on with your day.

The Friction Was the Point

My dad had a camera. Not a phone with a camera. A camera. A proper one with a roll of film that gave you 24 shots, maybe 36 if you were feeling extravagant.

Marketing Skills for AI Agents: Why Builders Should Care

Builders are living in a weird new era. An agent can scaffold a project, wire up an API, generate tests, refactor the mess, and ship a feature before you finish your second coffee.

From Network Plumbing to Application Intent: What AWS Networking Reveals About Infrastructure's New Role

Rob Kennedy, AWS Vice President of Network Services, opened his re:Invent 2025 keynote with a simple metaphor: atoms bond into molecules, molecules combine into structures, and those structures become complex organisms. The implication was clear, networking is no longer about connectivity. It’s about intent.

AWS Bedrock AgentCore Policy & Evaluations: AI Agent Governance at Scale

Many organisations are rushing into deploying AI agents with the same enthusiasm they had for serverless in 2016, great technology, terrible operational discipline. The pattern is predictable: build a proof-of-concept that works brilliantly in a demo, deploy it cautiously to production, then discover you have no idea how to govern what it’s actually doing once users interact with it at scale.

Beyond Vibe Coding: The Renaissance Developer Framework for Infrastructure Leaders

I watched Werner Vogels deliver what he’s calling his final AWS re:Invent keynote, and it struck me that he wasn’t talking about new services or feature announcements. Instead, he spent an hour articulating why the tools matter less than the person holding them. After 14 years of keynotes, Amazon’s CTO decided to hand the microphone to younger voices—but not before leaving infrastructure leaders and architects with something more valuable than a roadmap: a framework for how to think about engineering in the AI era.
