Amazon ElastiCache now offers R5 nodes, the next generation memory and performance optimized nodes to maximize network performance and CPU utilization in the Asia Pacific (Mumbai) AWS Region. R5 nodes feature the AWS 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 instances.

In addition, ElastiCache R5 nodes running Redis 5.0.3 with 4 or more vCPUs (cache.r5.xlarge and up) include enhanced IO optimization. This optimization 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 AWS Management Console.
