R5 nodes are now available on Amazon ElastiCache in the Amazon Web Services China (Beijing) region operated by Sinnet and the Amazon Web Services China (Ningxia) region operated by NWCD. R5 nodes feature the Amazon Nitro System, a combination of dedicated hardware and lightweight hypervisor that delivers nearly all of the compute and memory resources to the guest VMs.

R5 nodes offer up to 635.61 GiB of memory and 25 Gbps of aggregate network bandwidth. The ElastiCache R5 nodes are able to support between 59% and 144% more transactions per second than the similarly sized R4 nodes.

In addition, ElastiCache R5 nodes running Redis 5.0.3 with 4 or more vCPUs (cache.r5.xlarge and up) include enhanced I/O handling. This dynamic network processing capability delivers up to 83% increase in throughput and up to 47% reduction in latency per node.

R5 nodes are available at equivalent or lower costs than R4 nodes. You can further reduce your R5 costs by purchasing corresponding standard RIs available in three payment models – All Upfront, No Upfront and Partial Upfront.

To deploy Amazon ElastiCache on the new R5 nodes, please use the Amazon Web Services Management Console.
