Overview

Migrating from Alibaba Cloud OSS to Google Cloud Storage enables organizations to leverage Google's advanced data analytics, machine learning capabilities, and global network infrastructure. This guide walks you through the complete migration process using Cloney.

Migration Benefits

Google Cloud offers seamless BigQuery integration, advanced AI/ML tools, and a high-performance global network.

Prerequisites

  • A Cloney account with an active subscription
  • Alibaba Cloud OSS bucket with data to migrate
  • Google Cloud account with a GCS bucket created
  • Appropriate credentials for both services

Setup Access Credentials

Before proceeding, ensure you have configured least privilege access for both services:

Alibaba Cloud OSS: Least Privilege AccessGCP: Least Privilege Access Setup

Step 1: Add Your Alibaba OSS Source

  1. Log in to your Cloney dashboard
  2. Navigate to Jobs → Create New Job
  3. Select Alibaba Cloud OSS as your source provider
  4. Enter your Alibaba Cloud credentials:
    • Access Key ID: Your RAM user AccessKey ID
    • Access Key Secret: Your RAM user AccessKey Secret
    • Region: The OSS region (e.g., oss-cn-hangzhou)
    • Bucket Name: The name of your source bucket
  5. Click Validate Connection to verify access

Step 2: Configure Your GCS Destination

  1. Select Google Cloud Storage as your destination provider
  2. Enter your GCP credentials:
    • Service Account JSON: Upload or paste your service account key file
    • Project ID: Your Google Cloud project ID
    • Bucket Name: The name of your destination GCS bucket
  3. Click Validate Connection to verify access

Step 3: Start the Migration

  1. Configure optional settings (prefix filter, storage class, metadata)
  2. Review your migration configuration
  3. Click Start Migration
  4. Monitor progress in the Jobs dashboard
Migration Complete

Once finished, verify your data in the Google Cloud Console and update your applications.

Storage Class Mapping

Alibaba OSS storage classes map to GCS storage classes as follows:

Best Practices

  • Test with a subset first: Run a pilot migration with a small subset of data to validate your configuration.
  • Select the right region: Choose a GCS region close to your primary user base.
  • Enable object versioning: Consider enabling versioning for added protection.
  • Plan for BigQuery integration: If using BigQuery, consider bucket location for optimal performance.
