Region name.oms-cluster.Service ID |
This VPC endpoint service allows OMS to communicate with the master node in the migration cluster to manage migration tasks. For details, see VPC Endpoint Service Configuration. |
Security groups |
No |
Yes |
2 |
oms_cluster_sg_master_Cluster ID |
This is the security group of the master node in the migration cluster. It enables the communication between OMS and the migration cluster. For details about the security group settings, see Security Group Settings for the Master Node. |
oms_cluster_sg_agent_Cluster ID |
This is the security group of the list and migration nodes in the migration cluster. It enables communication between nodes in the migration cluster. For details about the security group settings, see Security Group Settings for List and Migration Nodes. |
