** Kubernetes Requests and Limits: A Guide to Efficient Resource Management

Kubernetes is a powerful container orchestration platform that relies on resource requests and limits to ensure efficient and fair resource allocation. These features allow users to define the minimum (requests) and maximum (limits) amount of CPU and memory required by each container.

Requests guarantee a minimum amount of resources for a container, while limits prevent containers from consuming excessive resources, which can cause bottlenecks or even crash the node. By setting both requests and limits, users can optimize resource usage, ensure fair distribution, and prevent unexpected container failures.

Best practices include setting realistic values, monitoring performance, and adjusting resource values as needed. Kubernetes provides tools like Vertical Pod Autoscaling (VPA) to help with resource management. By understanding and utilizing these features, users can create a more efficient and resilient Kubernetes cluster.
