Hidden Costs of Inter-Zone and Inter-Region Data Transfer
Your database just replicated 50GB of user data from your primary server in Virginia to a backup in California. Cost: $1. But when that happens 200 times a day, every day, it adds up to $6,000 per year just to keep your data safe. Whether your applications span multiple zones within a region or stretch across continents, the way data moves can quickly turn small line items into significant monthly bills. Understanding where your data moves across zones and regions is the first step in predicting and controlling these hidden costs.
