# 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? <a href="#tai-sao-nen-su-dung-glb" id="tai-sao-nen-su-dung-glb"></a>

* **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.
