Vertical Pod Autoscaler

Vertical Pod Autoscaler (VPA) is a tool used in cloud computing to automatically adjust the resource allocations—like CPU and memory—of individual application components (pods) in real-time. It helps ensure each application runs efficiently without wasting resources or crashing due to insufficient capacity. VPA observes the application's performance and automatically increases or decreases its resources as needed, optimizing overall system utilization and maintaining smooth operation. Think of it as a smart thermostat that dynamically adjusts heating or cooling to keep your environment comfortable, but applied to digital applications.
