Can you detail/link resources about "21C architectures" and "pilot light pattern"? Thanks!
Either way, GP is using obscure terminology at best.
> The term pilot light is often used to describe a DR scenario in which a minimal version of an environment is always running in the cloud. The idea of the pilot light is an analogy that comes from the gas heater. In a gas heater, a small flame that’s always on can quickly ignite the entire furnace to heat up a house
Sure, I’m being nitpicky, but that’s a terrible explanation of the purpose of a pilot light in a legacy furnace.
