Difficult Architecture Adaptation
The architectures of applications on the cloud are complex. DR technologies or products must adapt to different architectures. In addition, distributed systems and databases have high DR technology requirements.The architectures of applications on the cloud are complex.

High DR Requirement
Enterprise applications are deployed on the cloud and therefore have high DR requirements. Specifically, they require that services can quickly restore if an accident occurs (RPO = 0).Enterprise applications are deployed on the cloud and therefore have high DR requirements.

Inconvenient DR Drill
On-cloud DR lacks orchestration drills. Traditional manual drills take a long time, and involve both hardware and software, which is very inconvenient.On-cloud DR lacks orchestration drills.

Strict DR Reliability Requirement
On-cloud applications demand cross-region or even 2 site 3 DC DR capabilities to prevent huge losses caused by natural disasters such as typhoons and earthquakes.On-cloud applications demand cross-region or even 2 site 3 DC DR capabilities to prevent huge losses caused by natural disasters such as typhoons and earthquakes.
Typical Scenarios
-
Cross-AZ DR
-
Cross-Region DR
-
On-Cloud 2 Site 3 DC DR
Cross-AZ DR
The DR system is deployed in two AZs in the same region. Synchronous replication at the storage layer is used to provide DR protection between AZs. When the AZ where the production system is located becomes faulty, services can be switched to the DR system with only a few clicks.
Cross-Region DR
When the production system becomes faulty, services switch rapidly to the DR system. The production and DR systems are deployed in different regions, which effectively prevents system failures due to regional disasters and thereby provides higher reliability.
On-Cloud 2 Site 3 DC DR
Aggregates cross-AZ synchronous replication and cross-region OBS capabilities to effectively cope with large-scale regional disasters, thereby improving data reliability and service continuity.
Production and DR systems are in different regions, providing higher reliability.
Drills are performed as required, which does not affect the production service system.

Success Stories
-
With multi-AZ deployment, intra-city active-active DR, remote DR assurance, and visualized DR GUI, Huawei helped Vmall enhance service availability and simplified O&M. Vmall can now easily cope with demand during flash sales, hacker attacks, and high O&M costs. -
Local IDC+Hybrid Cloud Disaster Recovery from Huawei reduced DR costs and shortened the project construction period. With this solution, BRC can now implement cross-AZ DR and perform DR drills at any time.
