MCP en Producción: Por Qué el Model Context Protocol Va a Rediseñar tu Arquitectura de Agentes (y Cuánto Te Va a Costar Ignorarlo)

Tu equipo lleva semanas intentando que sus agentes de IA accedan de forma fiable a herramientas externas: una base de datos, una API de CRM, un sistema de ficheros. El resultado habitual es una colección de adaptadores artesanales, prompts que encodan contexto a mano y pipelines que se rompen cada vez que cambia un endpoint. El coste de mantenimiento se dispara antes de que el sistema llegue a pro...

The Boring Protocol That Quietly Ate the Cloud

This is a submission for the Google Cloud NEXT Writing Challenge Act I — A Scene You've Already Lived It is 2:47 AM. You have been staring at the same error trace for three hours. Your AI agent — the one you spent two weeks fine-tuning, the one your manager called "the future of the team's workflow" — is broken. Not because the model is wrong. Not because your logic is flawed. It is...

Kubernetes Building Blocks(1)

Introduction If you liken Kubernetes to an ocean, those individual drops that make up the ocean are the core building blocks: Namespaces, Pods, ReplicaSets, Deployments, Labels, etc. Our focus here will be on the first two mentioned.

How to Build Agent Memory That Doesn't Forget

The Problem Every AI developer hits this wall: your agent works great on day one, then degrades silently. It starts making worse decisions, using fewer tools, hallucinating more confidently. You've built observability, so you see the degradation—but you can't fix what you can't remember. The real issue? Most agent memory architectures are designed for storage, not for continuity. ...

Things Developers Get Wrong About the Backend for Frontend Pattern

Since I published my overview of the Backend for Frontend (BFF) pattern, the questions I've received fall into surprisingly consistent patterns. The same misunderstandings come up again and again, from developers who genuinely want to build secure apps. Most of these misconceptions aren't just academic. They lead teams to ship apps with real security gaps while believing they've done the right th...

Getting Your Own Team to Actually Use the Agent You Built

Part 1 of 2 on agentic system adoption. A 25% bump in individual AI usage correlates with a 1.5% drop in delivery throughput and a 7.2% drop in delivery stability. That's not a hot take — that's the 2024 DORA report, surveying thousands of engineers across hundreds of orgs. Worse: in a randomized controlled trial from METR on experienced open-source developers, engineers expected AI tools to spe...
