Metrics Server

Metrics Server is a component in Kubernetes that collects and aggregates resource usage data, such as CPU and memory, from running applications and nodes within a cluster. It provides real-time metrics that help manage and optimize the performance of containerized workloads. This data enables automatic scaling, monitoring, and decision-making to ensure applications run efficiently without manual intervention. Essentially, Metrics Server acts like a health meter, giving the system a snapshot of resource consumption to support smart, resource-aware operations.
