Definition
Traffic distribution refers to the strategic allocation of network traffic across multiple paths, resources, or servers. This process ensures that no single point becomes overloaded, thereby improving performance and reliability. It works by employing various methods like load balancing algorithms or DNS-based routing to direct incoming requests to available and optimal destinations. Effective traffic distribution is crucial for maintaining application availability, preventing service disruptions, and optimizing resource utilization, especially under high demand. For instance, a popular e-commerce website might distribute user traffic across several web servers to handle peak shopping periods. This differs from simple routing, which typically follows a single predetermined path, whereas distribution actively manages multiple options. Concepts of traffic distribution are frequently assessed in certifications like CompTIA Network+ and AWS Certified Solutions Architect Associate.
