This Guidance demonstrates how to configure a cell-based architecture for Amazon Elastic Kubernetes Service (Amazon EKS). It moves away from typical multiple Availability Zone clusters to a single Availability Zone cluster. These single Availability Zone clusters are called cells, and the aggregation of these cells in each Region is called a supercell. These cells help to ensure that a failure in one cell doesn't affect the cells in another, reducing data transfer costs and improving both the availability and resiliency against Availability Zone failures for Amazon EKS workloads.
