Amazon ElastiCache for Redis adds dynamic network processing to enhance I/O handling in Redis 5.0.3. By utilizing the extra CPU power available in nodes with four or more vCPUs, ElastiCache transparently delivers up to 83% increase in throughput and up to 47% reduction in latency per node. That is in addition to the significant performance improvements delivered late last year with the introduction of R5 and M5 instances on the service. You can now benefit from the enhanced I/O handling to further boost application performance and reduce costs.

Amazon ElastiCache for Redis improves throughput and reduces latency by leveraging more cores for processing I/O and dynamically adjusting to the workload. These improvements work best for applications that require a large number of concurrent connections to the Redis server. No client-side changes are needed.

Amazon ElastiCache for Redis 5.0.3 with enhanced I/O handling is available in all AWS regions. To get started, log into the AWS Management Console.
