SAP Application AS and Other Services

This section describes the relationship between SAP application AS and other services.

Virtual Private Cloud (VPC)

All ECSs in the SAP application AS belong to the same VPC. They are isolated using VPC subnets and security groups for security.

Image Management Service (IMS)

AS uses a specified image to provision ECSs for installing AAS.

Elastic Cloud Server (ECS)

The instances added in a scaling action can be managed and maintained on the ECS console.

Key Management Service (KMS)

KMS encrypts and saves configuration files that contain sensitive information to prevent information leakage.

Domain Name Service (DNS)

Nodes in the SAP S4/HANA system resolve domain names using DNS.

Simple Message Notification (SMN)

After the SMN service is enabled for AS, you can use SMN to promptly send AS group information to users so that they can learn the AS group status.

Cloud Eye

If an alarm-triggered policy is configured, AS triggers scaling actions when an alarm triggering condition specified in Cloud Eye is met.
