Downtime in critical applications can significantly impact business operations. For instance, downtime in a Manufacturing Execution System (MES) can disrupt production, leading to business losses. Similarly, downtime in Hospital Information Systems (HIS) and Picture Archiving and Communication Systems (PACS) can affect patient care. Sangfor HCI's high resilience, achieved through a highly redundant cluster design with integrated local backup and off-site disaster recovery, ensures the uptime of critical applications.
