Application scenarios

Updated at:2025-11-11

On-premises IDC Accessing Multiple VPCs Across Regions

Realize interconnection between cross-region multiple private networks and your IDC data center through dedicated line connections and Cloud Smart Network, enabling multi-region disaster recovery deployment and improving security.

Hybrid Cloud Deployment

Interconnect on-premises IDCs with cloud-based private networks through dedicated line connections, leveraging the elastic computing capabilities and instant activation features of the cloud to flexibly and conveniently expand the application layer capabilities of data centers.

Data Backup and Disaster Recovery

Based on hybrid cloud deployment scenarios, build a fast and reliable transmission channel between on-premises IDCs and cloud-based private networks to easily realize data migration, backup, and disaster recovery.

Multi-IDC Interconnection

Realize interconnection between IDCs in the same region and across regions through dedicated line connection products and Cloud Smart Network, providing you with efficient, secure, and fast network transmission capabilities.
