7. Pricing Overview

Amazon Dax uses a pay-as-you-go pricing model, which means that you only pay for what you use. The pricing is based on the number of nodes in your cluster and the amount of data transferred.

Here are a few things to keep in mind when it comes to pricing:

• On-Demand Nodes: You can use on-demand nodes to pay for the capacity you use without having to commit to a minimum number of nodes.
• Provisioned Nodes: You can use provisioned nodes to reserve capacity in advance and save up to 70% compared to on-demand nodes.
• Data Transfer Costs: Data transfer costs are based on the amount of data transferred in and out of the Dax cluster.

To avoid common pitfalls, make sure to monitor your usage and adjust your cluster size and node type as needed.
