It’s a no-brainer. Proactive ops systems can figure out issues before they become disruptive and can make corrections without human intervention.
For instance, an ops observability tool, such as an AIops tool, sees that a storage system is producing intermittent I/O errors, which means that the storage system is likely to suffer a major failure sometime soon. Data is automatically transferred to another storage system using predefined self-healing processes, and the system is shut down and marked for maintenance. No downtime occurs.
