The running joke is that raspberry Pis are less expensive than an precise raspberry pie. Even though I would not pay out $50 to $a hundred for a pie to eat, the plan is to offer a extremely able laptop, with a smaller footprint, with constructed-in networking, running open source application, at a value that hobbyists, as properly as gurus, can manage.

I’ve made use of them for several years as IoT products, considering they can assemble, store, procedure, and transmit information, as properly as react to the information if wanted. Individuals are using a Pi on initiatives this kind of as producing bike using safer and other IoT/edge web-new growth.

Nonetheless, things are altering for the Pis.

I was happy to see the k3s project, which is a lightweight Kubernetes distribution for use in “resource-constrained environments.” It is open source as properly as optimized for ARM processors. If you’ve not guessed by now, this will make running a Raspberry Pi-based Kubernetes cluster feasible since this Kubernetes distribution is genuinely intent-constructed for the Pi, of course with some limitations.

This enabling technology lets cloud architects place Kubernetes clusters running containers outside of the centralized general public cloud on smaller personal computers that will perform closer to the sources of the information. The clusters are even now tightly coordinated, most likely even spreading an software concerning a general public cloud system and hundreds or even countless numbers of Raspberry Pis running k3s. Clearly it’s a kind of edge computing with countless numbers of use cases.

What strikes me about this sample of architecture is that low cost, edge-based products are acting like lightweight private clouds. They provision methods as wanted and use a most well-liked system this kind of as containers and Kubernetes. Of course, they have an upper limit of scalability.
