Business Benefits

The benefits of the Recommended Basic Architecture are:

• Ease of administration: Since a single cluster hosts static HTTP pages, servlets, and EJBs, you can configure the entire Web application and deploy/undeploy objects using the WebLogic Server Console. You do not need to maintain a separate bank of Web servers (and configure WebLogic Server proxy plug-ins) to benefit from clustered servlets.

• Reduced Architecture Costs: Using load balancing hardware directly in front of the WebLogic Server cluster enables you to use advanced load balancing policies for accessing both HTML and servlet content. For example, you can configure your load balancer to detect current server loads and direct client requests appropriately.

• Reduced Ownership Responsibility:

• Robust security: Placing a firewall in front of your load balancing hardware enables you to set up a De-Militarized Zone (DMZ) for your web application using minimal firewall policies.

• Optimal performance: The combined tier architecture offers the best performance for applications in which most or all of the servlets or JSPs in the presentation tier typically access objects in the object tier, such as EJBs or JDBC objects
