Types of Licenses

There are 3 Types  of licenses and their precedence,

• Enterprise Edition

The Enterprise Edition provides Failover and Clustering support.All machines running the Workflow Management Engine Service in a cluster will require a valid Enterprise Edition license. When a workflow engine service is stopped or the server goes out of the network (following a shutdown or restart), all requests to that server are stopped. The other Workflow Engine services in the cluster will resume all pending tasks for the shutdown server.

• Professional Edition

The Professional Edition is used to host applications in a live environment.There is no count limit for the Concurrent workflow execution for a Professional Edition license.

• Developer Edition

The Developer Edition is a Rapid Application Development Framework and Software Development Kit (SDK) for workflow software aimed at software developers. The Developer Edition is a 100% Embeddable, web based workflow engine.

The Developer Edition is a version used for the development activities, such as creating custom action and embedding AVEVA Workflow Management controls inside custom applications. This edition can be used for any type of development that needs Visual Studio. To build a Web-based process designer using Enterprise Console, the Developer Edition is not essential.

The limitation of This product cannot be used in a Production environment.
