|
| Virtual Private Cloud (VPC) | MRS clusters are created in the subnets of a VPC. VPCs provide a secure, isolated, and logical network environment for your MRS clusters. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Object Storage Service (OBS) | OBS stores the following user data: |
|
|
| | |
|
|
| | - MRS job input data, such as user programs and data files |
|
|
| | - MRS job output data, such as result files and log files of jobs |
|
|
| | |
|
|
| | In MRS clusters, HDFS, Hive, MapReduce, YARN, Spark, Flume, and Loader can import or export data from OBS. |
|
|
| | |
|
|
| | MRS uses the parallel file system of OBS to provide services. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Elastic Cloud Server (ECS) | MRS uses elastic cloud servers (ECSs) as cluster nodes. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Relational Database Service (RDS) | RDS stores MRS system running data, including MRS cluster metadata. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Identity and Access Management (IAM) | IAM provides authentication for MRS. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Simple Message Notification (SMN) | MRS uses SMN to provide one-to-multiple message subscription and notification over a variety of protocols. |
|
|
+--------------------------------------+-------------------------------------------------------------------------------------------------------------------------------------------+
|
|
| Cloud Trace Service (CTS) | CTS provides you with operation records of MRS resource operation requests and request results for querying, auditing, and backtracking. |
|
|

After you enable CTS, the system starts recording operations on cloud resources. You can view operation records of the last 7 days on the CTS management console. For details, see **Cloud Trace Service** > **Getting Started** > **Querying Real-Time Traces**.
