Hybrid & Multi-Cloud Connectivity
Organizations running workloads in mainland China often need to connect China-based cloud environments — including AWS China Regions and Azure operated by 21Vianet — or China branches to public cloud regions overseas. These environments are operated separately, and cross-border connectivity requires a separately designed and provisioned path. We coordinate connectivity options for supported architectures, taking bandwidth, latency, route availability, workload design, and applicable requirements into account. Options range from managed 50 Mbps-1 Gbps virtual connections through partners such as Megaport and Equinix Fabric, among others, to dedicated 1-100 Gbps physical connections for data-heavy workloads.
Key benefits
- Right-size your connectivity: managed 50 Mbps-1 Gbps through partners such as Megaport and Equinix Fabric, among others, or dedicated 1-100 Gbps — you decide
- A coordinated connectivity path between China-based environments and overseas public cloud regions
- Technical and carrier documentation coordinated for the selected design; requirements depend on the workload and data flows
- One provider for both domestic cloud-to-cloud links and China-to-overseas links — consistent pricing, consistent SLA, consistent support
- Production-proven with multiple enterprise customers running live workloads today
Who it's for
Enterprises running hybrid cloud architectures that need domestic cloud-to-cloud links, or to connect China-based infrastructure to AWS, Azure, or GCP. SaaS platforms, financial services, and organizations evaluating cross-border connectivity for mainland China workloads.
Our approach
We assess your cloud architecture and bandwidth requirements, then recommend managed or dedicated connectivity based on the route and workload. Managed options are sourced through partners such as Megaport and Equinix Fabric, among others. We coordinate provisioning and BGP configuration with the selected providers and document the technical design. Availability, delivery timelines, and permitted use depend on the provider, route, architecture, and applicable requirements.
Architecture overview
How it works
- 1
Access
Provision carrier handoffs and cloud interconnects to bring China-based sites and domestic cloud environments into the CIH connectivity core.
- 2
Backbone transport
Carry traffic across managed backbone capacity to the selected overseas public cloud regions.
- 3
Routing and resilience
Design primary and backup paths where supported, implement BGP routing policies, and coordinate each cloud provider’s interconnection requirements.

Private Site-to-Site Connectivity
End-to-end private connectivity between your China sites and the rest of the world, built from two circuit types that work together: DPLC for the domestic point-to-point legs between Chinese cities, and IEPL or MPLS for the cross-border leg. Both are Layer 2, so your own routing runs across the whole path, and both are uncontended, so latency, jitter, and packet loss stay stable through the evening peak instead of degrading with the public internet. We source from China Telecom, China Unicom, China Mobile, and alternative operators, then choose the combination that fits your route, bandwidth, and budget — and we hold the carrier relationships, so you sign one contract and escalate through one path. The same point-to-point capability covers routes that never touch China — two overseas sites, or a data centre and an office outside the mainland — on the same Layer 2, uncontended terms.

Build your network out of virtual routers and firewalls rather than physical appliances. We deploy RouterOS, VyOS, FortiGate, or Zscaler VSE as virtual instances wherever your traffic needs them — inside a cloud region, in a colocation cage, at an office edge — then interconnect them into one routed, policy-controlled network over our multi-carrier DIA and Private Connect underlay. No hardware procurement, no customs, no local IT team. Configuration, policy, OS updates, and 24/7 monitoring are handled for you, and you keep administrative access and full visibility.
