Amazon Redshift Reserved Instance pricing
Amazon Redshift Reserved Instance pricing is a billing construct that results in significant savings for on-demand clusters that are utilized 24x7. To get large discounts on the clusters for your data warehouse workload, you can reserve your instances. Once you have determined the size and number of clusters for your workload, you can purchase Reserved Instances (RIs) for discounts from 34% to 75% compared to on-demand pricing.
RIs can be purchased using full upfront, partial upfront, or sometimes no upfront payment plans. RIs can be purchased for up to 1 or 3 years. They are not tied to a particular cluster; they can be pooled across clusters in your account. The following representative chart shows the significant cost optimization you can get by using RI pricing for 1 year or 3 years for different instances:
