I have questions for Disaster Recovery - Active/Active Infrastructure Image below
- The diagram shows three Nodes to be installed. Where does Redis Enterprise software gets installed? Also do we need to purchase 6 Redis licenses for this environment?
- How does the load balancer work in this scenario? Also How many load balancers to purchased ?
- what kind of Shared storage is it referring to? How much-shared storage does it require?
- What version of ElasticSearch and Kibana is required? Is it free of charge?
- Why does it Require 3 nodes on each datacenter for Elastic Search and Kibana?
Explain to the above would be highly appreciated. Thanks in Advance
