With the use of limit and request resource usage of a POD can be controlled.
Request: The number of resources being requested for a container. If a container exceeds its request for resources, it can be throttled back down to its request.
Limit: An upper cap on the resources a single container can use. If it tries to exceed this predefined limit it can be terminated if K8's decides that another container needs these resources. If you are sensitive towards pod restarts, it makes sense to have the sum of all container resource limits equal to or less than the total resource capacity for your cluster.
