How Global Server Load Balancing Optimizes Website Performance?

Image
Global server load balancing (GSLB) manages and distributes traffic across multiple servers many of which are located in different geographical locations. This ensures that your website or application remains accessible and responsive to users even during peak hours or unexpected traffic surges.  By distributing the workload across multiple servers GSLB helps to avoid server workloads and decrease the possibility of downtime which results in a smooth and efficient user experience.  Now let's take a look at GSLB and how it works. What Is Global Server Load Balancing?  GSLB uses a DNS-based system that dynamically modifies the DNS answer based on the performance and availability of the data centers. This method is improved by using the Round Trip Time (RTT) statistic, which calculates the RTT between the client's Local DNS (LDNS) and each of the GSLB sites.  These measures are critical for GSLB to make intelligent load-balancing decisions, ensuring that traffic is dir...
