Amazon EC2 Announces the Availability of C5, C5d, R5, and R5d Instances in AWS China (Beijing) region, operated by Sinnet and AWS China (Ningxia) region, operated by NWCD

Amazon EC2’s next generation compute optimized C5 and memory optimized R5 instances are now available in AWS China (Beijing) region operated by Sinnet and AWS China (Ningxia) region operated by NWCD. The C5 and R5 instances offer the latest generation Intel® Xeon Platinum processors (formerly codenamed Skylake) and feature the Nitro System, a combination of dedicated hardware and lightweight hypervisor that aims to deliver performance indistinguishable from bare-metal performance.

C5 instances deliver the best price/compute performance in the EC2 product family, offering up to a 49% improvement in price/performance compared to C4 instances. C5 instances are ideal for running compute-heavy workloads like batch processing, distributed analytics, high-performance computing (HPC), machine/deep learning inference, ad serving, highly scalable multiplayer gaming, and video encoding.

R5 instances deliver 5% additional memory per vCPU and up to a 50% price/GiB improvement over R4 instances. R5 instances are ideally suited for applications such as high-performance databases, distributed in-memory caches, in-memory databases, and big data analytics.

C5 and R5 instances with local instance storage (C5d and R5d) are also available in these regions today.

C5 and R5 instances are supported across all EC2 pricing options including On-Demand, Reserved and Spot Instances, with up to a 90% discount from On-Demand prices.
