In OpenStack, there could be scenarios where the system capacities can be exhausted without any notification. We can use quotas that specify the operational limit to prevent such issues. For example, if we want to set the number of gigabytes allowed for each project, you can control it via quotas to optimize resource usage. We can enforce the quotas at the project and the project-user level. By changing the quotas, we can control and provide more terabytes on a compute node. We can use the dashboard to view default Compute and Block Storage quotas for new projects and update it from there.
