Egress Gravity

Egress Gravity is the pull a warehouse exerts on client data once reads, refreshes, and downstream dashboards depend on it. Storage price is the visible number; retrieval price is the gravity. An agency quoting a $0.02/GB storage rate can still hand a client a five-figure retrieval bill when a BI tool re-queries a multi-terabyte table daily. Flat-rate object storage changes the physics: Wasabi charges no egress or API request fees, and Backblaze B2 pairs free egress with white-label resale, so an agency can host client reporting under its own brand without metering every dashboard refresh. Storj pushes the same economics through a distributed node network with S3-compatible APIs. The framework matters at renewal: a client whose dashboards, exports, and AI agents all read from one warehouse faces real migration cost, and that cost is the agency's pricing power. Model egress before you model storage.
