Fleet Health Is the Product
#

The industry sells IoT as if data were the point. It isn’t. Data is the receipt. Fleet health is the product.

A thousand sensors in the desert, a gas meter in every flat of a rural town, a cold-chain tracker strapped to a pallet crossing a border — none of that is worth anything if the fleet degrades between my laptop and the real world. Every device that silently goes dark, every firmware bug that bakes in without a way out, every slot of flash with a bricked image — each of those is a direct cut into whatever value the product was supposed to deliver.

Mastering Agentic AI: The Routing Pattern

In my previous post, we explored Prompt Chaining — the simplest way to break a complex task into sequential steps. But real-world systems rarely follow a straight line. Users don’t come with labels on their foreheads telling you what they need. Sometimes they want to book a flight, sometimes they want a factual answer, sometimes they want something you didn’t even anticipate.

That’s where the Routing pattern comes in. And honestly, this is where things start to feel like you’re building something real.

The Vendor Lock-in Trap
#

For the better part of the last decade, the industry narrative around IoT has been dominated by a “Cloud-First” mentality. The premise was seductive: treat your edge devices as dumb pipes and offload the heavy lifting to the cloud’s infinite compute.

However, as we moved from prototypes to production at scale, cracks began to appear in this facade. Latency mattered. Bandwidth costs exploded. But most importantly, we realized that by adopting managed edge runtimes, we were walking into a trap of architectural dependency.

We are witnessing a massive shift in how we interact with Artificial Intelligence. We are moving from simple, reactive chatbots to Agentic Systems—autonomous entities capable of reasoning, planning, and interacting with the world to achieve complex goals.

But how do we actually build these systems? It’s not just about having a powerful LLM; it’s about the architecture around it. It requires structure, design, and a thoughtful approach to how the agent perceives and acts.
