Description: Load balancer scaling refers to the ability to increase or decrease the number of instances behind a load balancer based on traffic demand. This feature is fundamental in cloud computing environments, where workloads can vary significantly over time. Scaling can be automatic, where the system adjusts the number of instances without manual intervention, or manual, where an administrator makes decisions based on performance observation. Automatic scaling relies on predefined metrics, such as CPU usage, request latency, or the number of active connections, allowing applications to remain available and respond efficiently to traffic spikes. This flexibility not only optimizes resource usage but also helps reduce costs, as unnecessary instances can be turned off during low-demand periods. In summary, load balancer scaling is an essential tool for ensuring the availability and performance of applications in dynamic and ever-changing environments.
