International Transfer
Seamlessly migrate workloads, databases, and object storage across CloudNexus global regions with zero downtime, built-in compliance routing, and end-to-end encryption.
Overview
The International Transfer feature enables cross-border synchronization and migration of infrastructure assets between any two CloudNexus regions. Whether you're expanding into new markets, complying with data residency laws, or optimizing latency for international users, this tool handles the complexity of cross-region transfers automatically.
Transfers are supported between all 50+ CloudNexus data centers across NA, EU, APAC, LATAM, and Middle East. Cross-continent transfers automatically route through optimized peering networks.
How It Works
International transfers follow a four-phase process designed to maintain data integrity and application availability throughout the migration window.
Source Validation
System scans source region for compatibility, checks resource limits, and generates a migration manifest with dependency mapping.
Initial Sync
Full data snapshot is encrypted (AES-256) and streamed to the destination region via dedicated transfer tunnels.
Delta Propagation
Real-time change data capture (CDC) syncs incremental writes while the initial payload finalizes.
Failover Cutover
Global DNS updates, connection pooling drains, and traffic shifts to the new region with automatic rollback capability.
Security & Compliance
All international transfers inherit your account's security posture and comply with regional data governance frameworks.
- Encryption in Transit: TLS 1.3 with mutual authentication across all transfer tunnels.
- Data Residency Controls: Restrict transfers to approved geographic zones via IAM policies.
- Compliance Mapping: Automatic alignment with GDPR, CCPA, LGPD, PDPA, and HIPAA data flow requirements.
- Audit Logging: Immutable transfer logs exported to CloudNexus Audit Vault or your SIEM via Syslog/AMQP.
Transfer keys are generated client-side. CloudNexus infrastructure never holds decryption material, ensuring full regulatory compliance.
API & CLI Usage
Initiate and monitor transfers programmatically using the CloudNexus CLI or REST API.
# Initialize international transfer job cnx transfer init \ --source-region us-east-1 \ --dest-region eu-west-3 \ --workload-type database \ --encryption-profile zero-knowledge \ --compliance-mode gdpr \ --dry-run true # Output: Manifest generated. Estimated transfer time: 14m 22s
Once validated, remove the --dry-run flag to begin the transfer. Use cnx transfer status --job-id to track progress or hook into WebSocket events for real-time monitoring.
Frequently Asked Questions
No. International Transfer uses asynchronous replication with automatic DNS failover. For databases, we utilize logical replication to ensure zero data loss and sub-second cutover windows.
Yes. Cross-cloud transfers are supported via our Import/Export endpoints. You'll need to configure a secure tunnel or use our SFTP-compliant object gateway for initial staging.
Transfers are priced per GB processed, with volume discounts for migrations over 500 GB. Egress fees apply for cross-continent transfers, but inter-region sync within the same continent is included in your base plan.
