GSLB (Global Server Load Balancer) a.k.a. Multi-site Load Balancer
GSLB stands for Global Server Load Balancer. This type of load balancer goes beyond the traditional local load balancing and is designed for distributing traffic across multiple data centers or geographically distributed servers.
A GSLB load balancer is concerned with global or wide-area load balancing. It takes into account factors such as server proximity, server health, and geographic location to intelligently distribute traffic across multiple locations.
Key Features of GSLB (Global Server Load Balancer):
- Global Scale: Manages traffic distribution across multiple data centers or geographic locations.
- Health Monitoring: Monitors the health and performance of servers in different regions.
- DNS-Based Load Balancing: Uses DNS to direct clients to the most suitable server based on factors like proximity and load.
Use Cases of GSLB (Global Server Load Balancer):
- Ideal for applications with a global user base spread across multiple geographic regions.
- Suited for scenarios where high availability and disaster recovery are critical.
Layer-4(L4), Layer-7(L7), and GSLB Load Balancers
Load balancers play a critical role in distributing network or application traffic across multiple servers to ensure optimal performance, reliability, and scalability. Layer-4 (L4), Layer-7 (L7), and Global Server Load Balancing (GSLB) are different types of load balancing mechanisms designed to address various needs within network architectures.
