Cloud DB Migration with Real-Time Status Alerts

Scenario

DevOps engineers need to migrate on-premises databases to the cloud with zero downtime visibility. This workflow automates a full pipeline—uploading backups to OSS, restoring to RDS, syncing to Elasticsearch, and enabling cross-region replication—while routing real-time stage completion, progress, and failure events via EventBridge to DingTalk or Lark for immediate team awareness.

Integration steps

1. Upload Backup to OSS: Run ossutil cp /backup/full_dump.sql.gz oss://migration-bucket/ --acl private.
2. Initiate RDS Import: Call CreateMigrateTask with {"OSSBucketName": "migration-bucket", "OSSObjectKey": "full_dump.sql.gz", "DBName": "prod_db", "CheckDBMode": "SyncExecuteDBCheck"}.
3. Configure ES Sync: Use DTS API CreateDtsInstance with {"SourceEndpoint": {"Engine": "MySQL", "InstanceId": "{RDS_ID}"}, "DestinationEndpoint": {"Engine": "Elasticsearch", "InstanceId": "{ES_ID}"}, "MigrationType": "FULL+INCREMENT"}.
4. Enable Cross-Region Replication: Call ModifyDBInstanceAttribute with {"BackupPolicy": {"CrossRegionBackup": true, "CrossRegionBackupRegion": "cn-shanghai"}}.
5. Create EventBridge Rules: Use PutRule for pipeline telemetry. Pattern: {"source": ["acs.rds", "acs.dts"], "detail-type": ["MigrationTaskStatusChange", "SyncStatusChange"]}.
6. Attach Webhook Targets: Call PutTargets with {"RuleName": "db-migration-alerts", "Targets": [{"Arn": "arn:acs:eventbridge:...", "HttpEndpoint": {"Url": "https://oapi.dingtalk.com/robot/send?access_token=xxx", "HttpMethod": "POST", "Headers": [{"Key": "Content-Type", "Value": "application/json"}]}}]}.

Architecture

Migration artifacts flow from on-prem to OSS, triggering RDS data import. RDS and DTS emit lifecycle events to the EventBridge default bus. EventBridge evaluates JSON patterns, filters by stage, and routes payloads to DingTalk/Lark HTTP webhooks. Elasticsearch and cross-region replicas consume data in parallel, while EventBridge decouples pipeline telemetry from alert delivery, ensuring DevOps receives structured JSON alerts without polling consoles.

Prerequisites

• RAM role with AliyunRDSFullAccess, AliyunOSSFullAccess, AliyunEventBridgeFullAccess, and AliyunDTSFullAccess.
• Pre-provisioned OSS bucket, target RDS instance, and Elasticsearch cluster in the same VPC.
• DingTalk/Lark custom robot webhook URL with outbound IP allowlist configured.
• EventBridge service-linked role (AliyunServiceRoleForEventBridge) activated.

Common pitfalls

• Event Source Mismatch: RDS uses acs.rds, DTS uses acs.dts, and ES uses acs.elasticsearch. Omitting any source in the PutRule pattern leaves that stage unmonitored.
• Webhook Payload Format: DingTalk strictly requires {"msgtype": "text", "text": {"content": "..."}}. EventBridge forwards raw JSON by default; use an API Destination with a Transformation template or route through Function Compute to reshape the payload.
• OSS URL Expiry: RDS import fails with InvalidOssUrl if the pre-signed URL expires mid-task. Set Expires to 86400 seconds or use bucket-level RAM policies.
• Throttling on High-Throughput Sync: Concurrent DTS replication and ES indexing flood EventBridge. Configure RetryPolicy with MaximumRetryAttempts: 3 and BackoffRate: 2.0 on the webhook target to prevent dropped alerts.

Q: How can I execute a full cloud database migration with real-time progress notifications to DingTalk or Lark? A: You can enable this by wiring EventBridge to push real-time status notifications for each migration stage to DingTalk or Lark. This setup provides DevOps teams with end-to-end visibility into the multi-step pipeline, which typically spans OSS backup uploads, RDS imports, Elasticsearch synchronization, and cross-region replication.
