IAM

DWS uses Identity and Access Management (IAM) for authentication and authorization.

Users who have the DWS administrator permissions can fully utilize DWS. To apply for the administrator permissions, contact a user with the security administrator permissions or create a user with the administrator permissions. Users with the DWS database access permission can generate temporary database user credentials based on IAM users to connect to the database in a data warehouse cluster.

ECS

DWS uses an Elastic Cloud Server (ECS) as a node in the cluster.

VPC

DWS uses the Virtual Private Cloud (VPC) to provide a network topology for clusters to isolate clusters and control access.

OBS

DWS uses OBS to convert cluster data and external data, satisfying the requirements for secure, reliable, and cost-effective storage.

MRS

DWS uses MRS to migrate data from MRS to data warehouse clusters so that DWS can analyze and query the data after the data is processed by Hadoop.

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.
