Prices and availability are snapshots, not offers. Cost estimates keep the listed required plan constant, exclude optional services and additional ownership costs, and never convert currencies. “Mostly local,” “hybrid,” and “mostly cloud” describe broad architecture; individual features can follow different data paths. Unknown or undisclosed information is preserved instead of guessed.
