The automated scaling listener mechanism is a service agent that monitors and tracks communication between cloud service consumers and cloud services for dynamic scaling purposes. Automatic scaling listeners are usually deployed near the firewall to track the volume of customer-generated requests or processing demands. A common approach to horizontal scaling is to balance a workload across two or more it resources to increase performance and capacity beyond what a single it resource can provide. The load balancer mechanism is a runtime agent with logic fundamentally based on this premise. Load balancers perform a range of specialized runtime workload distribution functions: asymmetric distribution, workload prioritization, content-aware distribution (some content might need to be prioritized or distributed in compared to other ones). The load balancer mechanisms can exist as: multi-layer network switch, dedicated hardware appliance, dedicated software-based system (in server os) service agent (controlled by cloud management software)
