Public cloud refers to a cloud based on the standard cloud computing model, in which service providers make resources available to the general public over the Internet. The core attribute of a public cloud is its shared resources. HUAWEI CLOUD is a public cloud and provides the following cloud services to implement SAP system migration. You can use HUAWEI CLOUD services independently or together to meet your migration requirements. Table 1 lists the cloud services that can be used during the migration.

Service	Features
SMS	Server Migration Service provides P2V and V2V migration services to help you migrate applications and data from on-premises X86 physical servers or VMs on private or public clouds to HUAWEI CLOUD Elastic Cloud Servers (ECSs). SMS migrates SAP application servers while the applications are running, and migrates database servers after the database service is stopped. You can use SMS to migrate incremental data. For more information about SMS, see What is Server Migration Service.
IMS	If your SAP application servers can be converted into image files, and the types and OSs of the image files are listed in Formats and OSs Supported for External Image Files, you can create the SAP application server image files as private images on HUAWEI CLOUD, and use the images to quickly deploy new application servers. For details, see Creating a Linux System Disk Image from an External Image File and Creating a Windows System Disk Image from an External Image File.
OMS	Object Storage Migration Service is an online data migration service. If the source SAP system has object storage data (such as database backup files and software installation media) stored on a third-party cloud, the OMS can smoothly migrate the data from the third-party cloud to the HUAWEI CLOUD. Note: This service applies only to migrate objects storage from a third-party cloud. For details about how to use the OMS, see Object Storage Migration Service Introduction.
DES	Data Express Service is a massive data transmission solution. It allows transmitting a large amount of data using Teleport devices or disks (with external USB interfaces, SATA interfaces, or SAS interfaces) to HUAWEI CLOUD. DES helps to address issues facing massive data transmission such as high network costs and long transmission time. If the source SAP system has storage devices with a large amount of data, for example, the storage device where the database backup directory resides, you can use DES for migration. Whether to use DES depends on the amount of data and the network bandwidth. For details, see DES Application Scenarios. For more information about DES, see the DES Product Overview.
