Amazon OpenSearch Service expands support for Graviton4 (c8g,m8g & r8g ) instances

Amazon OpenSearch Service expands support for the latest generation Graviton4-based Amazon EC2 instance families. These new instance types are compute optimized (c8g), general purpose (m8g), and memory optimized (r8g, r8gd) instances. AWS Graviton4 processors provide up to 30% better performance than AWS Graviton3 processors with c8g, m8g and r8g & r8gd offering the best price performance for compute-intensive, general purpose, and memory-intensive workloads respectively. To learn more about Graviton4 improvements, please see the [blog](https://aws.amazon.com/blogs/aws/aws-graviton4-based-amazon-ec2-r8g-instances-best-price-performance-in-amazon-ec2/) on r8g instances and the [blog](https://aws.amazon.com/blogs/aws/run-your-compute-intensive-and-general-purpose-workloads-sustainably-with-the-new-amazon-ec2-c8g-m8g-instances/) on c8g & m8g instances. Amazon OpenSearch Service Graviton4 instances are supported for all OpenSearch versions, and Elasticsearch (open source) versions 7.9 and 7.10. Apart from the regions already supported, one or more than one Graviton4 instance types are now also available in following region: Asia Pacific (Hong Kong), Asia Pacific (Hyderabad), Asia Pacific (Jakarta), Asia Pacific (Melbourne), Asia Pacific (Osaka), Asia Pacific (Thailand), Europe (Milan), Europe (Paris), Europe (Zurich), Middle East (UAE), AWS GovCloud (US-West) and AWS GovCloud (US-East).
