Elastic Cloud Enterprise on AWS EKS

As a starting point, in order to securely deploy ECE on AWS EKS, I would start with the ECE reference guide on securing your installation, focusing on network segmentation, user access control, encryption (at rest and in transit), monitoring and logging. With AWS EKS, consider using EKS managed node groups with appropriate instance types and security configurations, leveraging IAM roles (manage access to ECE components within the EKS cluster), and configuring EKS cluster logging.
