A workload is the computational or transactional burden of a set of computing, networking, and storage tasks associated with an application. Similar apps with the same technology and tools can have radically different workloads under different circumstances or during different times. Workloads can often be measured by CPU or memory consumption, network traffic, requests, database queries, transactions, and so forth. In very basic, broad terms, an application is a thing that processes something; a workload is the processing that’s being done; and a use case is the reason that you do it. In the context of cloud computing and Kubernetes clusters, a workload can be seen as the amount of work that an instance of an app or part of an app performs during a certain time period.
