+    The experiment aims to check the ability of nodes to accommodate the number of replicas a given application pod.
+    This experiment can be used for other scenarios as well, such as for checking the Node auto-scaling feature. For example, check if the pods are successfully rescheduled within a specified period in cases where the existing nodes are already running at the specified limits.
