“Backplane” refers to the rear interior surface of an equipment cabinet, where there’s often a maze of electrical conductors for routing power/data around the various rack units or cards it can hold. Examples include blade servers, very serious routers, and theatrical lighting dimmer racks.

The system can be expanded and serviced (without interruption) by installing and removing modules, but the backplane is forever.

A hot SaaS startup purporting to be your backplane is about as backwards as it gets. Smart companies are using cloud services in exactly the opposite way: as temporary, interchangeable capacity slotted into a backplane they own.
