You can use skills to restrict execution of workflows to specific Distributed Execution Managers.

A skill is similar to a tag that you can apply to both workflows and DEM Worker instances. If a workflow is not associated with any skills, any DEM Worker can execute it. If a workflow is associated with one or more skills, then only DEM Workers that are associated with all of the same skills can execute it.

Skills are useful when a particular workflow requires a DEM installed on a host with specific prerequisites. For example, you may want to restrict cloud provisioning workflows to a specific DEM running on a host with the required network access to Amazon URLs.

Skills can also be used to associate workflows with a particular data center location. For example, you might install one DEM in your Boston data center and another in your London data center, and use skills to direct certain operations to one data center or the other.
