The working joke is that raspberry Pis are less expensive than an actual raspberry pie. While I wouldn’t pay out $50 to $100 for a pie to eat, the strategy is to give a extremely able computer, with a smaller footprint, with developed-in networking, working open up resource software program, at a cost that hobbyists, as perfectly as professionals, can afford to pay for.

I’ve made use of them for yrs as IoT equipment, looking at they can collect, store, process, and transmit knowledge, as perfectly as react to the knowledge if essential. Men and women are employing a Pi on initiatives these as earning motorbike using safer and other IoT/edge internet-new advancement.

On the other hand, things are altering for the Pis.

I was joyful to see the k3s venture, which is a light-weight Kubernetes distribution for use in “resource-constrained environments.” It is open up resource as perfectly as optimized for ARM processors. If you’ve not guessed by now, this will make working a Raspberry Pi-based mostly Kubernetes cluster possible due to the fact this Kubernetes distribution is seriously objective-developed for the Pi, of program with some restrictions.

This enabling engineering allows cloud architects position Kubernetes clusters working containers outside of the centralized public cloud on smaller desktops that will get the job done nearer to the sources of the knowledge. The clusters are even now tightly coordinated, potentially even spreading an software among a public cloud platform and hundreds or even thousands of Raspberry Pis working k3s. Clearly it is a form of edge computing with thousands of use circumstances.

What strikes me about this pattern of architecture is that inexpensive, edge-based mostly equipment are performing like light-weight non-public clouds. They provision means as essential and use a chosen platform these as containers and Kubernetes. Of program, they have an upper restrict of scalability.
