Workload	n/a

A binary deployed by operators to deliver some function of a service mesh application. Workloads have names, namespaces, and unique ids. These properties are available in policy and telemetry configuration using the following attributes:

• source.workload.name, source.workload.namespace, source.workload.uid
• destination.workload.name, destination.workload.namespace, destination.workload.uid

In Kubernetes, a workload typically corresponds to a Kubernetes deployment, while a workload instance corresponds to an individual pod managed by the deployment.
