When purchasing Amazon Reserved Instances (RIs), there is no need to stop your currently running EC2 or RDS instances. Buying a Reserved Instance is similar to purchasing a discount coupon; it applies a price reduction to the fees of your existing EC2 and RDS usage. For long-term AWS services, purchasing Reserved Instances can significantly reduce costs.
