High-Volume Web Application Architecture

Interactive visualization of a scalable web infrastructure

💡 Learn About This Architecture

Users connect through a firewall for security and access control

The load balancer distributes traffic across multiple web servers for scalability

Each web server has its own database instance for performance

A synchronization server keeps all databases consistent in near real-time

📌 This architecture demonstrates horizontal scaling—adding more servers to handle increased load rather than upgrading individual machines

💡 The load balancer is a single point of failure; production systems typically use redundant load balancers with failover capabilities

🎯 Database synchronization introduces complexity but allows each web server to have low-latency access to its own database instance
