Scaling Kubernetes for the Age of AI Superinfrastructures In our last post, we explored how AWS is reinventing the way we cool superclusters, with data centers that feel closer to thermodynamic laboratories than traditional server rooms. Cooling thousands of...

From cooling breakthroughs to orchestrating 100K-node Kubernetes clusters on Amazon EKS — see how hyperscale AI infrastructure is built at AWS.

Kubernetes autoscaling done right.
My friend & colleague Christian just wrote the book covering the good, the bad, and “why is this pod even here?” moments from running K8s in production.

Trump hits chips with 100% tariffs to force domestic production. Global supply chains shake—Apple pledges $600B to stay in the clear. Welcome to Trade War 2.0.

😂😂 That’s a whole other topic! The kids were blown away to learn you can launch PocketQubes—just 500g!—into space to run experiments. In their minds, satellites were always giant machines. Next stop: SpaceX and Project Kuiper!

My kids asked: “How do weather reporters get those heat maps?”

Couple of hours later we:
- Built a Python satellite tracker on a Raspberry Pi
- Planned an SDR ground station to capture real NOAA/METEOR images

All from one curious why? 🚀 #STEM #ArmDeveloper

Cooling the Future: Why AWS Invented a New System for the AWS P6e-GB200 UltraServer In our mission to offer the best place to run applications — not just today, but in the era of trillion-parameter models — we knew the NVIDIA Blackwell launch on AWS had to be more than fast GPUs at s...

AWS is reinventing datacenter cooling for the AI era.

Meet IRH‑X, a custom liquid cooling system built to handle the heat of trillion‑parameter models — with a nod to hollow core fiber and Blackwell UltraServers.

The Age of Super Infrastructures: Colossus vs Stargate A few years ago, we were amazed by hyperscale cloud regions. Today, we’re witnessing the rise of hyperscale AI universes.

Colossus vs. Stargate: The dawn of #SuperInfrastructures.
AI clusters moving from megawatts to gigawatts, SMRs powering the future, and AWS quietly building the most efficient ecosystem.
We’re not just running models — we’re architecting a silicon civilization.

Private visit to the historic Tío Pepe cellars.
The most inspiring spot wasn’t the barrels, but the founder’s dusty corner of experiments — a quiet lab where innovation met patience.

M8.8 earthquake off the coast of Kamchatka (21 km depth) detected 9567 km away!
- P & S waves clearly visible
- Strong energy in 0.7–2.0 Hz band
- Classic megathrust signature: shallow, powerful, and cleanly captured

What are the chances? You go in for a stress test with a cardiologist… and it turns out his son works at AWS!

What If AMD Had Won the Cloud Gaming War? There was a moment in my career — at a previous company — where we seriously considered building a gaming infrastructure fabric powered entirely by AMD: CPU + Radeon GPU, fully optimized and cost-effi...

We once explored building a gaming fabric on AMD (CPU + Radeon). Gaming studios loved it—until hyperscaler realities got in the way.
Now, with MI300X, EPYC Genoa & ROCm maturing… is AMD finally having its moment?

EPROMINT: The DIY CPU That Plays The Matrix A few nights ago, I stumbled upon a project that instantly made me think of my friend Darko Mesaros. If you've ever seen his live coding sessions, you know he's the kind of person who appreciates the ...

A handmade CPU. No IDE. No Git. No CI/CD. Just EPROMs, solder, and 1,800 lines of code.

EPROMINT isn’t just a CPU — it’s a love letter to old-school computing. Proof that with curiosity and wire, you can build magic without a billion-dollar fab.

From Microcontrollers to Megawatts: How Arm Quietly Took Over the Data Center A few years ago, Arm was mostly associated with smartphones, Raspberry Pi boards, and low-power IoT devices. Fast forward to today, and it's powering hyperscale data centers, enterprise-grade workload...

While everyone’s chasing GPU clusters, Arm has been quietly slipping into the heart of the datacenter.

Less heat. Lower cost. More performance-per-watt.

It’s not a side story — it’s the new foundation.

New blog: Open Hardware vs Patent Saturation
Is the open hardware movement under threat?
From MMUs to shady patents, here’s a deep dive into what’s really at stake.

Watching top engineers leave and reading the latest Intel headlines made me reflect:

What would you do if you had to reinvent a giant mid-fall?

Here’s my take on how Intel could rise again — if it dares to rethink everything.

On these hot summer nights, it’s the tropical evenings under the stars that bring peace. Just a few months ago, Amazon had 2 satellites — now there’s a whole wave lighting up the sky. Love it! @projectkuiper.bsky.social

It’s bit frustrating when the mind is racing ahead but the body isn’t quite there yet.

Full house at today’s @JOTBConf workshop on modernizing apps in the cloud!
We showed how to apply @Werner’s Frugal Architect laws—putting cost where it belongs: at the core of your architecture.
Sustainable, efficient, and built to scale. Kudos to @nocoot & Flamur!

🚨 Amazon Neptune just leveled up: now supports Graviton3 R7g and Graviton4 R8g instances — with up to 16% lower price and blazing-fast DDR5 memory. Faster graph queries, lower cost, and more scale.

Picture of AWS Solution architect showing 3 Graviton processors (v2, 3 and 4) as if it was a poker hand.

Graviton’s winning hand!

From Graviton1’s lightweight start to Graviton4’s 96-core, DDR5 power for memory-intensive apps, AWS Graviton chips will become the standard in the cloud. Ready to play? ♠️

Yesterday an old friend asked what a year at AWS looks like.
I just smiled.
Every gray hair is a lesson.
Every challenge is growth.
It’s not exhaustion — it’s evolution at high speed.
And I wouldn’t change a thing.

Thinking of ditching x86?⁣ Now’s the time.
Graviton + Spot = faster, cheaper, greener.
Most libs already support Arm—just recompile & fly.⁣
Ready to build smarter? Here’s your migration guide.

Spot’s got power—but those interruptions? Brutal.
Let Karpenter do the dirty work.
It replaces interrupted nodes fast so your app doesn’t even flinch.
