The key difference between a Load Balancing Service and an Application Delivery Controller (ADC) lies in their scope of functionality: 1. Load Balancing Service : Primary Purpose : Distributes network or application traffic across multiple servers to ensure no single server becomes overwhelmed, thus improving reliability and availability. Functionality : Focuses mainly on balancing traffic using algorithms like round-robin, least connections, or IP hash. Example Features : Layer 4 (Transport Layer) or Layer 7 (Application Layer) load balancing. Simple traffic management and server health checks. 2. Application Delivery Controller (ADC) : Primary Purpose : Provides advanced traffic management, security, optimization, and acceleration services in addition to load balancing. Functionality : ADCs not only load balance but also handle application security, SSL offloading, traffic optimization, and monitoring to enhance application performance and security. Example Features : Load balancin
