AWS announces Amazon Neptune I/O-Optimized

Today, we are announcing the general availability of Amazon Neptune I/O-Optimized, a new configuration for Amazon Neptune Database that provides improved price performance and predictable pricing for customers with I/O-intensive applications. With Neptune I/O-Optimized, there are zero charges for read and write I/O operations—you only pay for your database instances and storage usage, making it easy to predict your database spend up front. Neptune I/O-Optimized offers up to 40% cost savings for I/O-intensive applications where I/O charges exceed 25% of the total Neptune database spend. You can now choose between two configurations for Amazon Neptune Database: Neptune Standard or Neptune I/O-Optimized. For applications with low-to-moderate I/Os, Neptune Standard is a cost-effective option. For applications with high I/Os, Neptune I/O-Optimized provides improved price performance, predictable pricing, and up to 40% costs savings. You can switch your cluster with a single click in the AWS Management Console or with a command through the AWS Command Line Interface. Neptune I/O-Optimized configuration is supported on from Neptune version 1.3.0.0 and provisioned instances. You can switch existing database clusters to Neptune I/O-Optimized once every 30 days and switch back to Neptune Standard at any time. Neptune I/O-Optimized is supported for all available Neptune instance types and Neptune Serverless. Neptune I/O-Optimized is available in all [AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) where Neptune is available.
