👉 WAN engineering, or Web Application Network engineering, involves the design, implementation, and maintenance of network infrastructure that supports web applications and services distributed across multiple geographically dispersed locations. This field focuses on ensuring reliable, secure, and efficient communication between web servers, clients, and various network components like routers, switches, and firewalls. WAN engineers must manage complex network topologies, optimize data transmission, handle latency issues, and implement security measures to protect against cyber threats. They also deal with scalability challenges as applications grow, ensuring that the network can handle increased traffic and data volumes without compromising performance. Effective WAN engineering is crucial for the seamless operation of global web services and applications, providing a robust foundation for modern digital interactions.
