AWS offers Previous Generation Nodes for users who have optimized their applications around these nodes and have yet to upgrade. Previous Generation Nodes are still fully supported and retain the same features and functionality. Previous Generation Nodes are available through the CLI and API tools.

AWS Free Tier includes 750hrs of Micro Cache Node with Amazon ElastiCache.
We encourage you to use the lastest generation of nodes to get the best performance, but we will continue to support Previous Generation Nodes after new nodes launch. If you are currently using a Previous Generation Node and would like to see which one would be a suitable upgrade, see the table below and learn how the latest generation of nodes could benefit you.
Just like our current nodes, Previous Generation Nodes give you access to the capabilities of a familiar Memcached and Redis engines.

Pricing is per instance-hour consumed for each instance, from the time an instance is launched until it is terminated or stopped. Each partial instance-hour consumed will be billed as a full hour.
Reserved Nodes give you the option to make a low, one-time payment for each node you want to reserve and in turn receive a significant discount on the hourly charge for that instance. Amazon ElastiCache provides three Reserved Node types (Light, Medium, and Heavy Utilization Reserved Nodes) that enable you to balance the amount you pay upfront with your effective hourly price.
Based on your application workloads and the amount of time you plan to run them, Amazon ElastiCache Reserved Nodes may provide substantial savings over running on-demand nodes.
