1. Risks and Latency of Public Internet Transmission

In hybrid cloud architectures, data transmission quality determines success. Relying on the public internet or IPsec VPNs for massive data transfer means enduring unpredictable latency and security risks. Sensitive financial, customer, and R&D data are vulnerable to interception and DDoS attacks when transmitted over the open web.

2. Core Technology and Physical Isolation of Direct Connect

Wang Cloud provides dedicated cloud physical line solutions with two key mechanisms:

  • Absolute Physical Isolation: A dedicated fiber optic line connects your local router directly to the cloud provider's edge location, bypassing the congested public internet for the highest level of physical security.
  • Consistent Low Latency and Guaranteed Bandwidth: Unlike "Best-Effort" public bandwidth, Direct Connect provides guaranteed speeds from 1 Gbps to 100 Gbps. The exclusive routing path keeps latency stable in the millisecond range, essential for active-active database synchronization.

3. Multicloud Ecosystem: AWS, GCP, and Azure Direct Access

We partner with top carriers to provide seamless access to major cloud networks:

  • AWS Direct Connect: Supports private VIFs for VPCs and public VIFs for services like S3. We use AWS Transit Gateway to integrate multiple lines into a flexible hub-and-spoke architecture.
  • Google Cloud Interconnect: Offers Dedicated Interconnect for large bandwidth or Partner Interconnect for lower entry costs, with 99.99% SLA redundancy guidance.
  • Azure ExpressRoute: Provides reliable connections to Azure infrastructure and direct access to Microsoft 365 and Dynamics 365 for improved collaboration.

4. Consultancy Value in BGP Planning and Cross-border Deployment

Building cross-border cloud lines involves complex low-level engineering. Our architects manage hardware procurement (Cisco, Juniper, etc.), VLAN segmentation, and BGP dynamic routing. We implement multi-AZ redundancy to prevent outages from physical line damage, often pairing them with backup IPsec VPNs. Furthermore, Direct Connect reduces data egress costs, providing a high ROI for your high-speed network.
