Virtual Enterprise topology

Install the product first as a simple topology configuration to familiarize yourself with its features in a test environment. When you are familiar with the advanced features, you can design advanced topologies that apply specifically to your application server environment.

The following graphic represents a supported topology of the product. In this topology, an on demand router (ODR) is between the Web server and the node groups. The ODR, with the assistance of the autonomic managers, categorizes and prioritizes the work before routing work to the appropriate nodes. The deployment manager is the centralized management communication vehicle, as indicated by the dotted lines.

Install the deployment manager on a separate workstation from the application server nodes so that an outage of a single node, either planned or unplanned, does not impact both the application serving capacity and management capability.

[Version 6.1.0.3 and later] When you are using a single physical computer that is hosting multiple nodes, the deployment manager can run on one of the nodes, and application servers can run on the other nodes. The application placement controller has been updated to consider the placement decisions made by the deployment manager.

When you are familiar with the product in a simple topology, you can add layers of complexity to your test environment. Include a firewall to secure your environment, and stress test to see the product features in action. Typically, when the workload increases, you must ensure that you have enough resources to manage the workload and that the resources configure and function together. You can also include an Internet Protocol (IP) sprayer in the configuration to eliminate any single point of failure, and make the topology highly available. An IP sprayer distributes requests from one IP address to multiple IP addresses.
