Traffic Routing
Traffic routing is a networking and software development concept that involves directing data packets or requests from clients to appropriate servers, services, or endpoints based on predefined rules and policies. It is fundamental in distributed systems, cloud computing, and microservices architectures to ensure efficient, reliable, and scalable application delivery. Techniques include load balancing, path-based routing, and service discovery to optimize performance and availability.
Developers should learn traffic routing when building scalable web applications, microservices, or cloud-based systems to manage high traffic volumes, improve fault tolerance, and enable seamless deployments (e.g., blue-green or canary releases). It is essential for implementing features like A/B testing, geographic load distribution, and handling failover scenarios in production environments.
