Honestly, could be as valid with a setup that just involves running a bunch of VMs. > Low power consumption Yeah, well, a typical laptop should draw around 50W, which is what, like 0.05$ a day? > Commercial advantage: Run highly cost and power efficient data centers Hu, no, in terms of power efficiency per unit of work, you will not beat specialized hardware. > Infrastructure as code. Full CI/CD with kernel-level control, per node, for any OS. With SDN knowledge, confidently build your own cloud provider. Sure, also, blockchain, 5G, serverless, microwaves, rust, wasm Lets come back to earth for a second. There is objectively no purpose for this, except it's fun and nerdy. Do we really have to find excuses?

To be clear, the commercial utility refers to the skills, not the hardware.

You don't have the same IO latency between nodes using VMs unless you start messing around with artificial attempts at inducing latency on each node individually. It's much easier to accurately simulate real world networking by not bothering to simulate and just using real world networking. There's a huge difference between latency on a wire vs latency within a hypervisor, and you won't know what you've papered over through lower latency via VM until you move to real hardware.

Thanks for this, the other comments had left me, a layman, thinking this was actually useful instead of just for fun.

> Yeah, well, a typical laptop should draw around 50W, which is what, like 0.05$ a day? At least where I live that would be 1.2kWh and about 13 cents per day, around $4 per month, or around $50 per year if running 24x7. Pacific Northwest has I believe some of the cheaper power in the U.S. at 10-11 cents per kilowatt hour.
