The enterprise data center has two sites, Shanghai and Guangzhou. Shanghai serves as the primary site, while Guangzhou serves as the secondary site. Due to the office's location in Guangzhou, geographical limitations severely constrained and challenged the process required for building and managing data centers. To meet continued business growth and reduce maintenance costs, the company needed to consolidate the existing Shanghai and Guangzhou data centers, with the Guangzhou site serving as the production center and the Shanghai site as the backup center. The existing infrastructure was also upgraded, ultimately achieving the goal of a "two-site, three-center" architecture.
