DWS uses an ECS as a cluster node.
DWS uses the Virtual Private Cloud (VPC) service to provide a network topology for clusters to isolate clusters and control access.
DWS uses OBS to convert cluster data and external data, satisfying the requirements for secure, reliable, and cost-effective storage.
Data can be migrated from MRS to DWS clusters for analysis after the data is processed by Hadoop.
You can use Cloud Data Migration (CDM) to migrate data from multiple sources to DWS.
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.
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.
DWS users can view collected cluster logs or dump logs on the Log Tank Service (LTS) console.
DWS uses SMN to actively push notification messages according to your event subscription requirements, so that you can immediately receive a notification when an event occurs (for example, a key cluster operation).
DWS uses Domain Name Service (DNS) to provide the cluster IP addresses mapped from domain names.
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.
