Raspberry Webfarm: new upgrade

There’s a precise moment when you stop using technology and begin to truly own it. For us that moment came when we powered on the last node of the cluster, watched all the LEDs blink in unison and realized something simple: all our sites and our clients’ sites, our mail, our services run on our own hardware, in our own home, under our total control.

And it all runs on a handful of Raspberry Pis.

What a web farm is (explained properly)

Imagine a small, close-knit team instead of a single hero doing everything alone. A web farm is exactly this: several machines that split the tasks and cover each other’s backs. One node acts as the “orchestra conductor” and routes incoming traffic; the others work behind the scenes serving the sites, handling the data and taking care of the services.

The beauty is that no machine is indispensable. If one stops, the work goes on. If more power is needed, you add a node and off you go. It’s an infrastructure that breathes.

Why Raspberry Pis specifically

Here comes the part we enjoy most. People picture servers as roaring cabinets in a refrigerated room. We have something that sits comfortably on a shelf, draws as much power as a light bulb and makes no more noise than the fridge.

Raspberry Pis are the perfect choice for several reasons, all of them good:

• Ridiculously low power consumption. The entire cluster draws less than a single traditional desktop PC. You can keep it running 24 hours a day, 365 days a year, without feeling it on the bill.

• Negligible entry cost. Want to grow the farm? Add a board, not a server costing thousands of euros.

• Absolute silence. No fans, no whirring. They work and no one notices.

• Minimal footprint. The whole set fits in a space smaller than a shoebox.

And then there’s a satisfaction hard to put into words: seeing a board the size of a credit card handle dozens of websites with ease.

An orchestra of machines (literally)

We gave our nodes the names of great composers. It’s not just a quirk: it’s our way of reminding ourselves that a well-designed infrastructure works just like an orchestra. Each instrument has its part, the conductor coordinates the whole, and the result is a harmony that no single element could produce on its own.

Some handle the sites, some keep the files, some take care of automation, some act as a bridge to the outside world. Each with its own role, all playing the same score.

Independence is the real achievement

The deep reason we built all this isn’t the savings, even if there are some. It’s independence.

Today, entrusting your online presence to third-party cloud services is the norm. Convenient, sure. But it also means that your data, your sites and your mail live on machines you don’t control, subject to rules, prices and decisions that don’t depend on you. One day the terms change, another the fee goes up, another still a service is discontinued and you have to adapt.

With our web farm that problem simply doesn’t exist. The sites are with us. The mail leaves from us. We make the rules. If tomorrow we want to change something, we open a terminal and change it. No one asks our permission, no one sends us a surprise invoice.

It’s the difference between renting a home and owning it.

“Nice, but it’ll be an unstable toy.” No. And this is perhaps the aspect that makes us proudest.

The cluster is designed to be solid: loads are distributed, important data is replicated and secured with regular backups, and the system is built to keep working even when a single machine has a problem. The uptime we record speaks for itself. It’s not a tinkerers’ experiment: it’s real infrastructure, serving real sites, for real people and clients, every day.

Is it worth it? Absolutely yes

Building a Raspberry Pi web farm isn’t the most immediate choice on the market. It takes curiosity, a willingness to learn and a pinch of stubbornness. But the reward is enormous: you have your own infrastructure, which you understand down to the last detail, which consumes very little, which you can grow whenever you want and which doesn’t tie your hands to anyone.

Every time we look at those LEDs blinking, we know exactly what’s happening in there. And knowing that all that work runs on a handful of little boards costing a few tens of euros each… well, it’s absolutely awesome.

And this is just the beginning.
