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 AWS management console, CLI and API tools.

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. 

M3 nodes provide better, more consistent performance than M1 nodes. M3 nodes are also less expensive than M1 nodes.

M1   M3
No Latest Intel Xeon Processor Yes
Good I/O Performance Better
Good Price per Performance
Better

R3 nodes provide the latest Intel Xeon Processors, higher memory bandwidth, and superior I/O and network performance. R3 provides the lowest price point per GB of RAM of all ElastiCache nodes.

M2 R3
No Latest Intel Xeon Processors Yes  
No Enhanced Networking Yes  
Good Sustained memory bandwidth Better  
Good I/O performance Better  
Good Memory per cache node Better  
Good Price point per GiB of RAM Best  

T2 nodes are Burstable Performance Nodes that provide a baseline level of CPU performance with the ability to burst above the baseline. They are recommended for workloads that don't use the full CPU often or consistently, but occasionally need to burst to higher CPU performance, such as test and development environments, as well as small workloads. T2 nodes are less expensive than m1.small, m1.medium, and t1.micro nodes in most regions.

T1/M1.small T2
No Latest Intel Xeon Processors Yes
No Turbo up to 3.3GHz Yes
M1 only Supports Backup and Restore for Redis No  

Just like our current nodes, Previous Generation Nodes give you access to the capabilities of a familiar Memcached and Redis engines.

cache.m1.small 1 1.3 Low
cache.m1.medium 1 3.35 Moderate
cache.m1.large 2 7.1 Moderate

cache.m2.2xlarge 4 33.8 Moderate
cache.m2.4xlarge 8 68 High

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.
