Multiple deployment manager cells

The following figure shows an example of how you can implement an application over multiple WebSphere Application Server deployment manager cells.

Multiple cell topology

The example application runs simultaneously in two cells, each hosted on a different physical machine (Machines A and B). Load Balancer (known as Network Dispatcher in earlier releases) is used to distribute incoming HTTP requests between the two cells, presenting a single image of the application to clients. A backup Load Balancer node provides failover support.

Installing enterprise applications on the cluster in each deployment manager node ensures that identical versions of the application run in each cluster member. However, you administer each cell independently. Each cell has its own set of XML configuration files.

You can also run a different version of the application in each cell cluster. Because the cells are isolated from one another, you can also run different versions of the WebSphere Application Server software in each cell. For example, you can have a Version 5 cell and a Version 4 domain interoperating in your network.

Typical use

Topologies that incorporate more than one cell have the following advantages:

Using multiple cells has several drawbacks:
