Table 4 Mapping between deployment modes and scenarios Deployment Scenario Deployment Mode Access Mode PRD Distributed HA deployment NAT Parent topic: Solution Introduction
Public subnet: Network Address Translation (NAT) server ECS: allows you to access HANA ECSs using Secure Shell (SSH). SAP HANA Studio ECS: runs the SAP HANA Studio software.
This rule is required only when the SAP HANA Studio is deployed on a Windows ECS. 10.0.0.0/24 TCP 80 (HTTP) Allows users to access the NAT server using Hypertext Transfer Protocol (HTTP). 10.0.0.0/24 TCP 443 (HTTPS) Allows users to access the NAT server using Hypertext Transfer Protocol
Public subnet: A NAT ECS allows you to access SAP Business One nodes using SSH. An SAP HANA Studio ECS is an ECS running the SAP HANA Studio software. You can use the Remote Desktop Protocol (RDP) or SSH to access the SAP HANA Studio ECS and manage the SAP HANA database.

Relationships Between SAP NetWeaver and Public Cloud Services Elastic Cloud Server (ECS) Both SAP NetWeaver and NAT are deployed on ECSs. Elastic Volume Service (EVS) All the SAP NetWeaver ECSs have EVS disks attached.
Procedure Use PuTTY to log in to the NAT server with an EIP bound. Ensure that user root and the key file (.ppk file) are used for authentication. Then, use SSH to switch to the SAP HANA and SAP Business One nodes.
Procedure Use PuTTY to log in to the NAT server with an EIP bound. Ensure that user root and the key file (.ppk file) are used for authentication. Then, use SSH to switch to the SAP HANA and SAP Business One nodes.
Requirements on Other Nodes Other nodes include the NAT server and SAP HANA Studio nodes. For details, see Requirements on Other Nodes.
Configuring the Mapping Between SAP HANA Host Names and IP Addresses Procedure Use PuTTY to log in to the NAT server with an elastic IP address bound. Ensure that user root and the key file (.ppk file) are used for authentication.
Requirements on Other Nodes Other nodes include the NAT server and SAP HANA Studio nodes. For details, see Requirements on Other Nodes.
VPN VPN establishes a secure, encrypted communication tunnel between the VPN gateway of the VPC on HUAWEI CLOUD and the VPN gateway of your local data center, allowing you to directly use resources in the VPC through the VPN.

Gateway: specifies the gateway IP address of the subnet. Advanced Settings: If you set it to Custom, you need to configure the following parameters: Gateway: specifies the gateway IP address of the subnet. DNS Server Address: An external DNS server address is used by default.
The SAP NetWeaver ECS on the private subnet can be accessed through the NAT server. Click Next: Configure Advanced Settings. Configure parameters in advanced settings of the SAP NetWeaver ECS as prompted.
