GLB

Global Load Balancer (GLB) is a network traffic distribution solution designed for multi-region environments. Unlike traditional Load Balancers that operate only within a single region or local network, GLB can distribute traffic across servers located in multiple geographic regions.

Why Use GLB?

• Global Reach: Enables traffic distribution across servers located in different geographic regions.

• Improved Performance: Reduces response time by routing user requests to the nearest available server.

• High Availability: Minimizes risks and ensures service continuity even if one region experiences failures.

• Scalability: Easily add or remove servers from the pool without affecting system operations.

• Flexibility: Simplifies the configuration and management of Global Pools, allowing flexible load-balancing adjustments based on demand.

• Cost Optimization: Efficiently utilizes server resources by evenly distributing workloads.
