Since the explosion, Tianjin has attracted immense attention from across the country. Amidst the noise surrounding the city, there have been deliberate and reckless rumors. We reject such demonizing narratives; while we offer our prayers, we also maintain our stance with rationality.
According to incomplete statistics, major data centers in Tianjin include the National Supercomputing Center in Tianjin, Tencent Tianjin Data Center, ChinaNetCenter (VNET), GDS (Guowang Data), Huasheng Tiancheng, and others. Among these, Tencent’s data center is particularly large, housing 200,000 servers.
At 4:18 AM on August 13, the official Weibo account for Tencent Video’s Anime Channel announced that due to severe damage to the Tianjin server room caused by the explosion, some scheduled anime updates could not proceed as planned. They expressed their deepest apologies.
In today’s increasingly digital world, data has become the lifeline for both enterprises and other institutions. “With data, you live; without it, you perish.” This statement is far from an exaggeration. Calmly consider this: as IT professionals, what would be the consequences and losses if our data centers were within the blast radius? Therefore, we must always be prepared to handle unforeseen disasters in the future.
Here, we briefly introduce the concept of remote disaster recovery.
Forms of Remote Disaster Recovery
One approach is traditional disaster recovery: building one or more sets of identical applications or databases in different geographic regions to take over operations within a certain timeframe after a disaster occurs.
The other approach is cloud-based disaster recovery: establishing an IT system with equivalent functionality in the cloud. This system can monitor health status and perform failover with local servers. If one system fails unexpectedly (such as in the case of the explosion), the entire application system can switch to the cloud backup system, allowing customer systems and business operations to continue functioning normally.
Remote disaster recovery plays a crucial role in ensuring security and business continuity for enterprise applications and databases. Therefore, its outcomes differ significantly from those achieved through private clouds or public clouds alone.
What Can Remote Disaster Recovery Bring Us?
When a disaster strikes, critical enterprise data is protected, and information systems can be restored quickly to ensure continuous business operation.
Factors to Consider for Remote Disaster Recovery
- New data center site selection
- VPN performance and stability
- Network transmission stability
- Hardware costs
- Solution and implementation costs
Of course, specific implementation involves many more factors than those listed above. Is there a better solution to achieve more effective results? The answer is definitely yes. In this era of rapid internet development, cloud computing has already become widespread. If you don’t know what cloud computing is, then perhaps you are already out of touch.
Currently, leading domestic cloud providers such as Amazon Web Services China, Alibaba Cloud, and Tencent Cloud have become mainstream in China’s cloud computing market. Enterprises can combine cloud storage, cloud servers, cloud databases, and VPCs to architect a system where business operations remain completely unaffected even if the primary data center is lost.
Benefits of Cloud-Based Disaster Recovery
- No need to worry about hardware procurement or data center site selection
- Fast data transmission, mature technology, and stable bandwidth
- Easier maintenance later on, eliminating the need for on-site staff at the data center
- Solves most software procurement issues
Of course, remote disaster recovery is only meant to guard against the worst-case scenario. We hope it will never actually be needed. Prayers go out to the people of Tanggu, Tianjin, wishing everyone safety and peace!
