On-Demand Nodes let you pay for memory capacity by the hour your node runs with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs.
Pricing is per node-hour consumed, from the time a node is launched until it is terminated. Each partial node-hour consumed will be billed as a full hour.
With Reserved Nodes, you can make a low, one-time, up-front payment for each node you wish to reserve for a 1 or 3 year term. In return, you receive a significant discount off the ongoing hourly usage rate for the node(s) you reserve. Amazon ElastiCache provides Heavy Utilization Reserved Nodes for its current cache node families. To learn more about Reserved Nodes, please visit our Reserved Nodes page.
Backup storage is the storage associated with the automated and user-initiated snapshots you have taken. Amazon ElastiCache provides storage space for one snapshot free of charge for each active ElastiCache for Redis cluster. Additional backup storage is $0.085/GB every month (same price in all regions). Data transfer for using the snapshots is free of charge.
Amazon ElastiCache provides strong network level security by allowing access/data transfer only from or to the Amazon EC2 Instances you define as part of your Security Groups.
- There is no charge for data transfer between Amazon EC2 and Amazon ElastiCache within the same Availability Zone.
- While standard Amazon EC2 Regional Data Transfer charges of $0.01 per GB in/out apply when transferring data between an Amazon EC2 instance and an Amazon ElastiCache Node in different Availability Zones of the same Region, you are only charged for the Data Transfer in or out of the Amazon EC2 instance. There is no Amazon ElastiCache Data Transfer charge for traffic in or out of the Amazon ElastiCache Node itself.
As part of AWS’s Free Usage Tier, new AWS customers will receive free 15 GB of data transfer out each month aggregated across all AWS services for one year.
