Topology patterns and supported product features
A topology is the physical layout of the deployment environment. The product features and default usage depends on your choice of topology pattern.
If you are using the Deployment Environment wizard in the administrative
console to create the deployment environment, the availability of topology patterns on which you
base your deployment environment varies depending on the following conditions and configuration decisions:
- The operating system on which you have installed IBM® Business Automation Workflow
- The primary deployment environment feature and the complimentary feature
The information in Table 1 shows the
relationship between the topology patterns and product
features.
| Topology pattern | Number of clusters | Description | Supported products and features |
|---|---|---|---|
| Single Cluster | 1 | Messaging, application deployment target, and application support functions
are contained in a single cluster. This topology pattern is useful for synchronous messaging, proof
of concept, or application testing environments. A Single Cluster topology pattern is ideal for limited hardware. Because all of the components are installed in the same cluster, fewer physical machines are required. |
Supported by the following products:
|
| Application, Remote Messaging, and Remote Support | 3 | This topology pattern defines one cluster for application deployment, one remote cluster for the messaging infrastructure, and one remote cluster for supporting applications. | Supported by the following products:
