What is “Two-site Three-data-center” Architecture?

The "Two-site Three-data-center" architecture is a robust disaster recovery strategy that distributes your IT infrastructure across three data centers in two geographical locations.

This design ensures continuous business operation even if two of the three data centers fail, delivering maximum resilience for your most critical applications.

Production Center:
The primary site that hosts live services and user traffic.

Local DR Center:
Located within the same metropolitan area (typically within 100 km). It enables nearly zero data loss (RPO≈0) failover for high availability, serving as the first line of defense.

Remote DR Center:
Situated hundreds of kilometers away in a different region. It provides protection against large-scale disasters through asynchronous replication, acting as the ultimate safety net.

Benefits from “Two-site Three-data-center” Architecture

Business Continuity

Even if a data center fails, the business can be automatically switched to the backup center within minutes, ensuring uninterrupted business operations.

High Availability

Through the same-city active-active architecture, application-level multi-active is achieved, ensuring that critical business services never interrupt and providing an availability of over 99.99%.

Disaster Recovery Capabilities

It possesses comprehensive recovery capabilities ranging from same-city failures to cross-regional disasters, enabling it to calmly address business interruption risks of all scales.

Flexible O&M

It supports deployment across heterogeneous hardware and hybrid cloud environments, and enables centralized management through a unified platform, significantly improving operation and maintenance efficiency.

Compliance & Industry Regulatory

It meets the requirements of Network Security Level Protection 2.0 and industry regulatory standards for finance and other sectors, providing strong safeguards for business compliance.

Cost-efficient Scalability

By integrating and reusing resources, an enterprise-level disaster recovery system is built with more intensive investment.
