Cost vs Reliability Trade-off	concept	Cost & FinOps	The non-linear relationship between availability and spend, which makes each additional nine roughly an order of magnitude more expensive.
Egress Cost Data Transfer Out	concept	Cost & FinOps	The charge for moving data out of a cloud provider or across its zones and regions — usually the least-anticipated line on a cloud bill.
