Following are the required things for using A10 Harmony

  1. Web Application: The web application you want to use behind Harmony may be hosted anywhere but accessible from the A10 Lightning ADC(LADC).The application may be using HTTP or HTTPS protocols and might being served using one or more web/app servers.
  2. ARN (Only if application is in AWS): Using AWS' Identity and Access Management (IAM) service, an ARN with A10 Lightning  specified permissions should be created. Detailed steps for creating an ARN as well as required IAM policy document will be available via Harmony Portal during on-boarding. 
  3. DNS Entry: A DNS entry like or with DNS service provider of your choice is needed using which your user can access your application. Typically this will be a 'CNAME' record or an 'A' record in your domain's hosted zone file.

Additionally, if you have your application behind AWS Elastic Load Balancer (ELB), Harmony will be able to automatically discover your web servers rather than you entering them manually. Also if you are using AWS Route53 for DNS management, Harmony can change the DNS entry on your request rather than you doing it manually.
It is recommended that you keep this information handy while starting with on-boarding flow.
