Blueprint to improve resiliency and reduce data transfer costs for Amazon EKS workloads

Describe the solution you would like

This bulkhead architecture approach uses cells to ensure a failure in one cell doesn't affect others. This approach reduces inter-AZ data transfer costs, improve EKS application availability and resilience against AZ-wide failures. This design moves away from a multi-AZ Amazon EKS cluster solution, to a single AZ Amazon EKS cluster solution, with multiple Amazon EKS clusters per Region within each AZ. This essentially turns each Amazon EKS cluster into a cell in the bulkhead pattern. These individual single AZ Amazon EKS clusters are called as cells, and the aggregation of cells in each region a supercell.
