IAM

Your registered cloud account has full access to its resources and cloud services. If you need to assign different permissions to employees in your enterprise to access your CDM resources, Identity and Access Management (IAM) is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your cloud resources.

VPC

CDM clusters are created in the subnets of a Virtual Private Cloud (VPC). VPCs provide a secure, isolated, and logical network environment for CDM clusters.

MRS

CDM supports data import and export using MRS.

OBS

CDM supports data import and export using OBS, which also stores backup files and logs of CDM clusters.

Cloud Eye

CDM uses Cloud Eye to monitor cluster performance metrics, delivering status information in a concise and efficient manner, as shown in Table 1.

**Table 1** CDM performance metrics
Metric	Description	Value Range	Monitored Object
Bytes In	Measures the network inbound rate of the monitored object. Unit: byte/s	≥ 0 bytes/s	CDM cluster instance
Bytes Out	Measures the network outbound rate of the monitored object. Unit: byte/s	≥ 0 bytes/s	CDM cluster instance
CPU Usage	Measures the CPU usage of the monitored object. Unit: %	0% to 100%	CDM cluster instance
Memory Usage	Measures the memory usage of the monitored object. Unit: %	0% to 100%	CDM cluster instance

CTS

CDM uses Cloud Trace Service (CTS) to record operations for later query, audit, and backtrack operations. Table 2 displays the recorded CDM operations.

**Table 2** Key operations recorded by CTS

Deleting a cluster	cluster	deleteCluster
Modifying cluster configurations	cluster	modifyCluster
Starting a cluster	cluster	startCluster
Restarting a cluster	cluster	restartCluster
Importing a job	cluster	clusterImportJob
Binding an EIP	cluster	bindEip
Unbinding an EIP	cluster	unbindEip
