What is global server load balancing (GSLB)?

Global Server Load Balancing (GSLB) enhances application performance and resilience by directing client traffic to the nearest healthy point of presence, thereby minimizing latency and ensuring uninterrupted service even during failures. By fine-tuning DNS resolution, GSLB routes users to the closest server, significantly improving loading times and user experience. This system not only distributes network traffic across various global Points of Presence (PoPs) to prevent server overloads but also supports disaster recovery by redirecting traffic to backup sites during outages. ngrok enhances GSLB by offering a cloud-based, zero-configuration solution that combines GSLB with firewall and reverse proxy functionalities, ensuring secure and efficient traffic routing via its global network of PoPs. This setup simplifies IT operations by automatically routing traffic to new locations without manual configuration, providing resilient and high-performing connections for users worldwide.
