## How IBM is Revolutionizing Global Server Load Balancing with DNS and Real User Monitoring (RUM)

IBM is disrupting the load balancing market by leveraging Domain Name System (DNS) and Real User Monitoring (RUM) data in Global Server Load Balancing (GSLB) to deliver premium connectivity for business-critical applications. While GSLB may not be necessary for every business, it is vital for enterprises with a global user footprint. Traditional in-line load balancers, though common, have their downsides, including choke points and a lack of visibility into inbound traffic sources.

IBM’s GSLB solution, NS1 Connect, utilizes DNS and RUM data to overcome these challenges, providing better resilience, faster connection performance, and cost-effectiveness. DNS, as the underlying technology for most in-line load balancers, effectively controls traffic across the entire connection pathway, reducing points of failure without the need for additional appliances or endpoint licenses. RUM data offers real-time insights into user experiences and assists in routing traffic for optimal connectivity.

IBM NS1 Connect GSLB, a SaaS authoritative DNS solution, is poised to transform the load balancing market by offering superior performance and lower costs compared to traditional in-line solutions. With the increasing demand for better connectivity, IBM’s innovative approach to GSLB is a game-changer for both consumers and network teams.

### Summary:

IBM is redefining the landscape of Global Server Load Balancing using DNS and Real User Monitoring data to improve application connectivity and performance. By combining these technologies, IBM’s GSLB solution is set to provide enhanced resilience, faster connections, and cost-effectiveness, disrupting the traditional in-line load balancing market.

**FAQs**

1. **What is Global Server Load Balancing (GSLB)?**
Global Server Load Balancing (GSLB) is a method used to distribute incoming network or application traffic across multiple servers in different data centers. It helps in optimizing resource utilization, maximizing throughput, minimizing response time, and avoiding overload on any single server.

2. **How does DNS play a role in GSLB?**
DNS, as the underlying technology for most in-line load balancers, effectively controls traffic across the entire connection pathway, reducing points of failure without the need for additional appliances or endpoint licenses.

3. **What is Real User Monitoring (RUM) data, and how is it used in GSLB?**
Real User Monitoring (RUM) data provides instant information about user experiences directly from devices and can form the basis of routing decisions that optimize traffic flow for better connectivity and improved user experiences, enhancing the overall resilience and performance of the application.

4. **How does IBM’s GSLB solution differ from traditional in-line load balancers?**
IBM’s NS1 Connect GSLB leverages DNS and RUM data to overcome the limitations of traditional in-line load balancers, providing better resilience, faster connection performance, and cost-effectiveness without the need for additional hardware or licenses.
