"High Availability in Workload Automation (HA in WLA)"
When designing a software system, most of the work focuses on the functional areas of the product like the user interface, system storage, and processes running in the background. The possibility of long-term downtime--due to hardware, operating system, or software failure--often gets neglected.
High availability is a key way to prevent such downtime. The concept is a design and implementation approach that ensures a software system stays available to its users even when there are hardware or software problems.
