Scenario Description
In this scenario, you migrate the SAP system that is deployed on a third-party cloud. The supported server OSs are listed in OSs Supported by Different Types of ECSs. There is no restriction on the database. In addition, other cloud services, such as object storage service, can be involved in. After the migration to HUAWEI CLOUD, the database, OS, and system architecture remain unchanged. The involved cloud services of other cloud vendors will be changed to those of HUAWEI CLOUD.
This scenario is similar to the previous one. However, there are some differences:
- You can easily adjust the network bandwidth between the third-party cloud platform and HUAWEI CLOUD. The maximum bandwidth can be hundreds of Mbit/s.
- Generally, the system architecture does not need adjustment. If the on-premises system architecture is complex, you need to replan the deployment architecture of the system on the cloud.
- Generally, an on-premises system contains only physical servers or VMs. A system on a third-party cloud may contain cloud service resources.
Figure 1 shows an example. You can use the same system architecture as the third-party cloud to reduce migration complexity.
