The blog post elaborates on scaling Elasticsearch by optimizing the Cluster State, which isn't about the amount of data stored but the metadata's size and rate of change. The post suggests minimizing cluster state size by practices such as avoiding field overuse, distributing data across multiple clusters, and preferring fewer, larger nodes. These adjustments, alongside others like strict mappings and efficient alias usage, contribute to a more manageable and scalable Elasticsearch environment

The article discusses the impact of Topology Aware Hints (TAH) on network traffic in Amazon Elastic Kubernetes Service (EKS). TAH, introduced in Kubernetes version 1.23, helps in routing traffic efficiently within the same Availability Zone (AZ) to benefit latency-sensitive workloads and reduce inter-AZ data transfer costs
