Firebolt Unit is a normalized measurement of consumption. FBU normalizes consumption management irrespective of node type, number of nodes, number of clusters, duration of consumption, etc. Thanks to Firebolt’s multidimensional scaling, per-second billing, and auto-stop/start capabilities, compute consumption can be a fraction of a minute. FBU eliminates the need to keep track of individual node types, nodes, and the number of clusters. There’s no binding to specific instance types, so you are free to use pre-paid credits on any node type.
