ArcGIS Workflow Manager Server is scalable and accommodates both small and large deployments. When you begin, you may start small and install all the components on a single machine. As you deploy the production site, or if the site needs to accommodate more users, you can add more Workflow Manager Server machines to the site.
Single-machine deployment
In a single-machine deployment, Workflow Manager Server is installed and federated on a single ArcGIS Server machine.
High-availability deployment
Workflow Manager Server can be configured as a highly available deployment to help ensure that your organization meets system uptime requirements. Workflow Manager Server supports the configuration of a multiple-machine, high-availability site, in which two or more Workflow Manager Server machines can be administered and used as a single logical unit.
A highly available Workflow Manager Server deployment can be configured with any supported highly available ArcGIS Enterprise deployment. ArcGIS Server must be installed but does not need to be licensed as a GIS server on the Workflow Manager Server machines. Once the Workflow Manager machines are set up, they must be configured for high availability in the Workflow Manager configuration file.
Note:
Workflow Manager Server cannot be deployed using a single-machine high-availability configuration.
