Intra-city dual-active data center

Business challenge

Data consistency of hypermetro in the same city

It is difficult to effectively guarantee the data consistency of enterprise key services across data centers

Disaster recovery costs that cannot be reduced

The project period is long, the hardware and software products involved are many, the investment cost is high, and the construction effect is uneven

Business continuity across data centers

In traditional backup and recovery mode, service recovery takes too long to meet key service continuity requirements

Solution architecture

Scheme characteristics

Cross-center data assurance mechanism

Relying on the storage hypermetro capability of UCloudStack across data centers, strong consistency data can be guaranteed across data centers. On the premise that the network quality between data centers meets the requirements of the solution, RPO=0, RTO≈0, and zero data loss can be achieved

Cross-center failover mechanism

When an extreme fault occurs in a data center, the cloud instance can be migrated to a physical machine in a healthy data center without any modification. The disaster recovery (RPO=0, RTO<5min) can be implemented across data centers

Cross-center online migration mechanism

Provides multi-data center migration capability, so that online migration is not limited to the same data center. The cross-data center online migration mechanism can effectively balance resources among multiple data centers and carry out the planned cross-data center live migration

Distributed management

A set of managed services to support the health of the private cloud platform itself while keeping the private cloud healthy across multiple data centers. Distribute management functions and resources across different data centers to enable distributed management and collaboration across data centers

Scheme value

Lower the threshold for the construction

Based on UCloud's own cloud computing data center construction capabilities, the basic capabilities required for the construction of active-active data centers are standardized and productization. Customers can quickly complete the construction of active-active data centers

Further improve application business continuity

The UCloudStack active-active data center construction solution can realize cross-data center failover mechanism, that is, cross-data center downtime migration and cross-data center online migration, without transforming the service system, thereby improving the business continuity of the system again

Strengthen the construction foundation of duplex applications

The necessary infrastructure of the active-active data center is quickly completed, and certain failover mechanisms are built in to prepare for the transformation of active-active applications. Users only need to add the cross-data center traffic scheduling mechanism and the cross-data center high availability mechanism of the service system for applications.
