I have installed aerospike on 2 VMs of amazon cloud, I want to form a aerospike cluster with these 2 machines. Not sure how to do it.
You can also check some recommendations for AWS on this page, which has a link for the specific configuration for mesh (as AWS does not support multicast).
Finally, if you are going to be accessing your cluster through the nodes public IPs, make sure you configure the access-address to the public IP but have the nodes mesh-see-address-port to be the nodes private IPs.
