SAP Netweaver on AWS?

We're trying to install the SAP Netweaver 7.5 on AWS. Does anyone have any idea about what inputs should we provide in below input fields?

• NetWork Infrastucture Details:

  Availability Zones

  CIDR block for RDP & Bastion access

• SAP NetWeaver Cluster setup and configuration

  R53 private hosted zone (We've migrated from GoDaddy to R53 with our '.com' address)

  SAP instance number

Are there any other fields that need to be taken care of OR need a change from default values populated in the default SAP Netweaver on AWS template.
