Your data center infrastructure plays a significant role in your disaster recovery and business continuity strategy. During a natural disaster or a cyberattack, your primary data infrastructure could be seriously compromised and even go offline altogether. Enterprises need backup infrastructure resources to fall back on in these instances.
A disaster recovery data center is considered hot, warm, or cold, depending on its state of readiness and the degree to which it is fully built out. Instantly ready would be hot, while an unfinished facility would be cold.
Any natural disaster, like a tsunami, flooding, earthquake, tornado, wildfire, etc., will likely affect a broad area. The backup resources must be spaced far enough from the primary resources so that they wouldn’t both be affected by the same disaster. For example, data centers would ideally have different power utility suppliers. However, they must be close enough to the same user audience so that the latency is acceptable.
At Prime Data Centers, we often refer to our Sacramento site as an ideal backup to San Francisco Bay Area data centers. It has lower flood risk, lower seismic risk, and has a different power utility. On the other hand, it is close enough to the Bay Area to provide minimal latency.
The same risk management thinking applies to the digital side. Backup data infrastructure resources must be sufficiently firewalled from your primary infrastructure. If not, a cyber attack could affect a cloud-based backup resource as much as it affects the primary resource.
