Term	Kind	Topic	What it is
Cloud Egress Cost	concept	Network & Egress Costs	The asymmetric pricing where data entering a cloud is free and data leaving is charged, which shapes architecture more than most teams expect.
Data Gravity Data Inertia, Locality Pull, Egress Pull	concept	Network & Egress Costs	The tendency of large data to attract compute and services toward it, because moving data across billed or slow boundaries is expensive while moving computation to the data is cheap.
