Global Server Load Balancing (GSLB)` enhances application performance and resilience by steering client traffic to the closest healthy point of presence through fine-tuning DNS resolution, ensuring uninterrupted service and reducing latency by leveraging a global network of servers. GSLB operates independently of traditional load balancers, offering advantages such as automatic routing, secure connections, and simplified app delivery. It plays a vital role in disaster recovery, directing traffic to backup sites when needed to minimize disruption and ensure business continuity. With ngrok's hosted GSLB, IT operations are simplified, eliminating the need for provisioning, ongoing maintenance, and configuration setup.
