01The layered map

Layer by layer, from the open taxonomy.

Each domain this platform draws on, with its layers and the technologies in each. Open a layer for what each technology does and the standard behind it.

Compute and edge

Compute placed where data is produced and decisions are needed: the device, far, near and regional edge tiers, multi-access edge computing, modular edge data centres including the AI tower in a box, servers and accelerators, storage, power and cooling, ruggedisation, fleet orchestration, OTA and GitOps, and the hardware trust that makes remote sites safe to run.
