Vertical Pod Autoscaling (VPA):?

• Automatically adjusts CPU and memory limits for the pods to optimize

performance.

• This is useful when pods experience resource contention but might not need

horizontal scaling.

Relevance to microservices: Kubernetes auto-scaling is essential in microservices to

ensure that each service can scale independently based on its needs, without manual

intervention. This allows the system to remain performant and available even as load

fluctuates.
