Digital Edge explains China disaster recovery site selection

Digital Edge explains how to choose a China disaster recovery site and positions its Beijing facility, PEK1, as a recovery option for a Shanghai primary.

• The article argues that for many in-scope workloads, the DR site must remain inside China because personal information and important data collected in China must be stored onshore under Article 37 of the Cybersecurity Law, while synchronous replication is practically limited to about 100 kilometres and longer distances imply asynchronous replication.
• It says a same-metro standby can cover facility failure but not regional events; for a Shanghai primary, the preferred pattern is a different metro and different operating entity. It then maps this to PEK1 in Beijing, operated with Chuanjun Information Technology (Shanghai) Co., Ltd., and cites 2N UPS redundancy, 100% dual-power SLA, CQC GB50174-2018 Level A, Cybersecurity Protection Level 3, ISO/IEC 27001, SOC 2 Type II, PCI DSS, 7.8 MW, 1,801 cabinets, and 8,361m².
