Scenario:

This scenario is inspired by High Availability - Data Replication and is an attempt to replicate that setup on AWS:

• we have 2 EC2 instances created from Red Hat AMI (RHEL-7-JBEAP-7.4.0_HVM_GA-20210909-x86_64-0-Access2-GP2)
• the first instance is configured as Live node
• the second instance is configured as Backup node

This scenario presents one main flaw:

• limitation: according to AMQ team, data replication over the networks is only supported on VMs (= EC2 instances) in the same data-center (they suggested the following documentation is relevant here messaging-ha#split_brain); according to AWS (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html?icmpid=docs_ec2_console) the most restrictive Placement strategy is "Cluster placement groups" which places EC2 instances in a single Availability Zone; each Availability Zone is usually backed by one or more physical data centers, with the largest backed by as many as five; this means Data Replication would be supported only on those Availability Zone which are backed by a single data center

questions

Is it worth to provide support for this scenario on AWS?
