Previous generation nodes

AWS offers Previous Generation Nodes for users who have optimized their applications around these nodes and have yet to upgrade. Previous Generation on-demand nodes will reach End-of-Life on December 1, 2022. We recommend that you migrate those nodes to the newer generation node types before December 1, 2022. Previous generation RI (Reserved Instance) nodes will reach End-of-Life on June 1, 2023. We recommend that you migrate those nodes to the newer generation node types before June 1, 2023.

This notice applies to all commercial Regions and AWS GovCloud (US). For C1, T1, M1, M2, M3, and R3 node family types in the Beijing (BJS) region operated by Sinnet and Ningxia (ZHY) region operated by NWCD, they will reach End-of-Life on October 15, 2024.

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

Please note the one-time fee per node is non-refundable.

* This is the average monthly payment over the course of the Reserved Instance term. For each month, the actual monthly payment will equal the actual number of hours in that month multiplied by the hourly usage rate or number of seconds in that month multiplied by the hourly usage rate divided by 3600, depending on the Elasticache instance type you run. The hourly usage rate is equivalent to the total average monthly payments over the term of the Reserved Instance divided by the total number of hours (based on a 365 day year) over the term of the Reserved Instance.

** Effective hourly pricing helps you calculate the amount of money a Reserved Instance will save you over On-Demand pricing. When you purchase a Reserved Instance, you are billed for every hour during the entire Reserved Instance term you select, regardless of whether the instance is running. The effective hourly price shows the amortized hourly instance cost. This takes the total cost of the Reserved Instance over the entire term, including any upfront payment, and spreads it out over each hour of the Reserved Instance term.
