What is best approach to support 6 API gateways at 9.x versions with a single developer portal.
We have a customer at present who is running 2 Older SOA gateway nodes with one Dev portal 3.x. Customer wants to add 4 more instances with existing SOA gateway nodes making it 6. Customer is not keen on migrating to Dev portal 4.x versions .
What is the best approach without impacting performance
- Adding all instances to one cluster and spread the nodes of the cluster across 3 different data centers
- Configure replication across all 3 clusters and let portal be pointing to the same cluster as it is now.
