Reviewing Aspera Transfer Cluster Manager Requirements

Before launching the Aspera Transfer Cluster Manager, take the following steps:

Confirm that you have received an ATC Manager image and node image from Aspera.

Important: It is no longer necessary to make a copy of the GA releases of ATC Manager or Aspera node images. However, if you are using a custom or pre-release version, Aspera recommends that you make a copy of the AMIs.
Set up your DNS service and assign your domain to it.
ATC Manager requires a DNS service that has APIs in order to programmatically modify the host entries used for the cluster, and that supports low TTL settings for the DNS host entries. The Route 53 and SoftLayer DNS services meet both of these requirements.
If you already have a domain: Register your domain with the DNS service, following the instructions for that service.
- Route 53: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/CreatingNewSubdomain.html.
  Important: When configuring Route 53, the SOA (Start of Authority) entry in Route 53 has a configuration option for the negative result TTL (for example, how long a resolver should consider a negative result for a subdomain to be valid before retrying). Aspera recommends setting this to 10 seconds (as shown by A in the following image).
- SoftLayer DNS: https://knowledgelayer.softlayer.com/procedure/configure-dns
If you want to purchase and register a domain with the same service:
- Route 53: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/CreatingNewDNS.html.
- SoftLayer DNS: https://knowledgelayer.softlayer.com/procedure/register-new-domain

Once you have reviewed all the requirements, you may proceed to launch the Cluster Manager image by following the instructions found in Booting the Aspera Transfer Cluster Manager Image.
