* Resource-locale pair: When setting allocation rules, you must specify both a resource type (the Amazon resource like EIPs, ALBs, or RDS clusters) and a locale (the Amazon Region or Local Zone where the rule applies). Allocation rules are scoped to this resource type and locale combination. For example, if you're setting a policy for EIPs in us-east-1, you can set up to 10 rules for that specific resource-locale pair*.
