EdgeComputer

A computer-like EdgeDevice described by aggregate CPU, RAM, and storage specs. Internally creates standard EdgeCPUComponent, EdgeRAMComponent, and reuses the provided EdgeStorage so loads can be sized against component capacity.

When to use this class

Use EdgeComputer for general-purpose edge compute hardware where CPU, RAM, and storage matter. Use EdgeAppliance for sealed appliance-style hardware described only by total power and embodied carbon. Use EdgeDevice for fully bespoke hardware.
