What is a key aspect of Alibaba Cloud's infrastructure that contributes to redundancy?

The key aspect of Alibaba Cloud's infrastructure that contributes to redundancy is the geographic distribution of resources. This approach entails placing data centers in multiple locations across various regions. By distributing resources geographically, Alibaba Cloud enhances the availability and resilience of services. If one data center experiences issues due to natural disasters, power failures, or other localized problems, traffic can be rerouted to other operational data centers, allowing for continuous service delivery.

This redundancy strategy is crucial for maintaining high availability and minimizing potential downtime, which is essential for businesses that rely on cloud services for critical operations. The vast geographic spread ensures that data is replicated and can be accessed even if one part of the infrastructure goes offline. This contrasts with centralized storage, localized server farms, or single point backups, which do not provide the same level of protection against large-scale outages and can create vulnerabilities in service continuity.
