This is why we have reviewed the topic of virtual clusters using namespaces and different contexts, delimiting the use of resources such as RAM and/or CPU, allowing/restricting the access of users or groups (RBAC) through the definition of roles, clusterroles, rolebinding and clusterrolebinding.

We also saw the importance of probes and how they impact the health of our application, which ultimately generates resource usage metrics, which are leveraged by objects such as HPA (Horizontal Pod Autoscaler) and Cluster Autoscaler to create pods or nodes in a cluster according to defined thresholds to alleviate the load on the cluster.
