WebSphere Application Server Network Deployment clustering mechanism

WebSphere Commerce configures a WebSphere Application Server stand-alone profile for each WebSphere Commerce instance that is created. To cluster WebSphere Commerce machines, you must create a WebSphere Application Server deployment manager profile. If you install WebSphere Application Server Network Deployment on the same node as WebSphere Commerce, your hardware requirements are greater than if the node runs WebSphere Commerce only.

Important: When you create a clustered environment, ensure that the original node remains active. WebSphere Commerce relies on the WebSphere Application Server profile on the original node for maintenance tasks such as applying fixes.

Review the following topics for different types of clustering for WebSphere Commerce:

The following diagram shows an example of a WebSphere Commerce cluster:

This diagram shows how WebSphere Commerce clustering functions. The WebSphere Application Server Deployment Manager node manages multiple WebSphere Commerce Nodes. These WebSphere Commerce nodes handle requests that are received from the Web server node and access the database node if needed. The response is then sent back to the Web server node, and out to the customer's browser.
