OBS
DWS uses OBS to convert cluster data and external data, satisfying the requirements for secure, reliable, and cost-effective storage.
MRS
Data can be migrated from MRS to DWS clusters for analysis after the data is processed by Hadoop.
CDM
You can use Cloud Data Migration (CDM) to migrate data from multiple sources to DWS.
Cloud Eye
DWS uses Cloud Eye to monitor cluster performance metrics, delivering status information in a concise and efficient manner. Cloud Eye supports alarm customization so that you are notified of the exception instantly.
CTS
DWS uses Cloud Trace Service (CTS) to audit your non-query operations on the management console to ensure that no invalid or unauthorized operations are performed, enhancing service security management.

DNS
DWS uses Domain Name Service (DNS) to provide the cluster IP addresses mapped from domain names.
ELB
With Elastic Load Balance (ELB) health checks, the CN requests of a cluster can be quickly forwarded to normal CNs. If a CN is faulty, the workload can be immediately shifted to a healthy node, minimizing cluster access faults.
