Global Load Balancing and Traffic Management
Master DNS-based routing, geographic traffic management, health checks, and failover strategies for globally distributed applications.
When a user types your URL into their browser, a chain of decisions determines which server actually handles their request. At the simplest level, DNS resolves the domain to an IP address. But for a globally distributed application, that resolution is where intelligent routing begins.
Global load balancing is the practice of distributing user traffic across multiple servers, regions, or data centers based on rules you define — geographic proximity, server health, current load, or custom logic. It is the traffic control system for your application, and getting it right means users always reach a healthy, fast server.
The Load Balancing Stack
Traffic routing happens at multiple levels, and understanding the stack helps you know which tool to use for which problem:
