Hi,
I think of Workload Automation as a modern view of Workload Scheduling, be that managed from your traditional data center or perhaps now based in the Cloud as a service. This ties all the aspects of IT jobs or tasks that need to be linked together in as efficient manner as possible such that you can track and manage that process.
I think of Cloud Automation as something much wider. From the automation of building systems, deploying applications, patches, enabling DevOps and much much more.
