Elastic Search - Load balancer - AWS Cloud

Assuming there are two ACTIVE CLUSTERS in two different REGIONS in Elastic Search and both are receiving data and both the Regions having GSLB Configuration in place.

I want to switch the network to Active Region automatically without any data loss in case of failures in one region. All the data to be routed to ACTIVE Cluster region if other cluster fails.

How can we achieve this. Please suggest. Thanks a lot in advance.

You really need to ask this via AWS support channels since it's basically an AWS networking question.

EDIT: never mind, you can't use Elastic Cloud in this case with two clusters actively receiving data in different regions.
