What did he mean by disk limits?

Disk limits generally refer to restrictions on disk space usage that can be set at the operating system, virtual machine, or cloud service level.

For example:

• User quotas — limits on the amount of data a specific user can store.
• Container restrictions — in Docker, a limit can be set on the size of a volume or the total amount of used space.
• Cloud limits — in cloud platforms (AWS, GCP), the disk size or the number of input/output operations can be limited.

This is important to prevent disk overflow, which can lead to application or system failures.

For example: in Kubernetes, a resource limit can be set for PersistentVolumeClaim to control the maximum storage size allocated to pods.

Thus, disk limits refer to mechanisms for controlling and restricting disk space usage to ensure system stability and predictability.
