Q: How will Route 53 work with VPC?

Route 53 can assign both public and private IPs. To configure Route 53 for a private IP, edit your Cluster Configuration and modify the "dns_manager_config" section:

...  
"dns_manager_config": {    
    "type":"AWS_Route 53",
    "dns_names": {
          "all_public": "c1-all",     
          "available_public": "c1",
          "all_private": "c1-all-prv",   
          "available_private": "c1-prv" 
    },    
    ...  
},  
...

Q: Can the cluster run servers in multiple availability zones?

Yes, if the cluster is launched into a VPC defined with multiple subnets in different availability zones. ATCM automatically distributes nodes across all VPC subnets defined in the cluster configuration in a round-robin fashion.

Q: How do I determine what version of Aspera Enterprise Server is used by my cluster nodes?

The version can be retrieved in the Cluster Manager UI or with an ATCM API call.

Cluster Manager UI: Click the cluster's Description tab and locate the Version Information section. Alternatively, click the number in the Nodes column to open the Monitor Nodes page, then click the node row to view node details, including Version Information.

API call: Run the following command:

$ curl -u username:password https://localhost:4999/v1/clusters/cluster_id/nodes | jq '.[].node_info | .es_version'

The version of ascp, the FASP transfer tool that is used by Enterprise Server, is returned in output that is similar to the following:

{
  "ascp_version": "3.7.4.145547",
  "creation_date": "2017-07-06T20:20:04.000Z",
  "version": "3.7.4.145547"
}
