Vertical autoscaling
Also calledVPA, vertical pod autoscaler, automatic rightsizing
Adjusting a workload's requests and limits automatically from observed usage, rather than changing how many copies there are. It solves the request-guessing problem that wrecks bin packing, and it is most useful on workloads that cannot be scaled out at all. Historically it required a restart to take effect, which is why many teams run it in recommendation-only mode and let humans apply the numbers.
