Amazon Elasticsearch Service now supports the next generation M5 (general-purpose) instances, which offer superior performance at lower costs compared to previous-generation instances.  

The M5 instances are built on the Nitro system, a collection of AWS-built hardware and software components that enable high performance, availability, and security. These instances are powered by Intel Xeon Platinum processors with Intel’s newest vector processing instruction set, delivering faster compute performance. They also feature enhanced networking based on the Elastic Network Adapter (ENA), which provides increased network bandwidth, making shard relocation faster and reducing the time for cluster updates and instance recovery. These instances are also EBS-optimized with up to 3.5 Gbps burst support for smaller instance sizes (below 4XL), which helps maximize indexing and search performance. Further savings are available via reserved instance (RI) pricing.
