CloudQuotation deploys multiple data centers and implements disaster recovery policies to ensure high availability and rapid service recovery during failures. This approach maintains data integrity and availability across different failure scenarios.
Intra-region deployment
CloudQuotation deploys data centers in multiple zones within the same region, providing data-center-level disaster recovery. If a data center becomes unavailable due to network disconnections, power outages, or other disasters, CloudQuotation continues to provide highly consistent services with zero service interruption and zero data loss during failovers. This helps meet the strict recovery time objective (RTO) requirements of key business systems.
When you deploy data distribution nodes to implement an intra-city disaster recovery solution, CloudQuotation offers the following advantages:
-
A data center in a nearby geographic region was selected to reduce data transmission latency.
-
Data can be synchronized across multiple data centers based on the real-time data replication policy.
-
CloudQuotation is built on a multi-active architecture that allows each node to process service requests independently and eliminates the distinction between primary and secondary nodes.
Cross-region deployment
CloudQuotation deploys multiple data centers across regions for enhanced data backup and disaster recovery. If data centers in one region are damaged by a catastrophic event such as an earthquake or tsunami, data centers in another region remain available. You can use one of the following methods:
-
If all services that are deployed in one region are unavailable, you can switch to services deployed in other regions.
-
You can access multiple regions at the same time. If a service fails in one region, services in other regions can work as expected.
