AWS Cost Optimization for Retail & Online Stores
How retail & online stores cut AWS costs: the layers to optimize, the tools that help, and calculators to size your savings.
Most retail & online stores pay for cloud and AI capacity they don't fully use — commitments and right-sizing usually recover 20–40%*.
The biggest line is rarely the one being watched — one lever (caching, routing, or a commitment) usually moves it most.
Without per-team attribution, no one owns the number — showback makes the savings stick.
