Deploy on Amazon Elastic Kubernetes Service (EKS) using Helm Chart
Amazon EKS runs multi-zone Kubernetes clusters by default and has no support for single-zone deployments. As described in Amazon EKS Features, the managed control plane runs in multiple availability zones by default to protect cluster administration against zone failures. Similarly, the worker nodes are automatically placed in multiple availability zones of the chosen region to protect the cluster itself from zone failures.
Refer to the Multi-zone Amazon EKS instructions for getting started with YugabyteDB on Amazon EKS.
