AS-Java Technical System Landscape

The complex communication patterns and links reflect the versatile functions that the AS-Java can perform in your system landscape. The AS-Java, and respectively the J2EE Engine, have an open and standards-based architecture that enables communication with a number of partners in your system landscape, for example Web clients, databases, AS-ABAP and other systems.

The versatility of the AS-Java and the number of communication partners, however, increase the system security risks, especially when used in open environments such as the Internet. Therefore, you can protect your productive systems by using firewalls to deploy the AS-Java system instances in a separate security zone in your system landscape. In addition, you can use application gateways, such as proxy servers, to filter and authenticate communication requests for the AS-Java and related application components.

For architectural considerations when deploying the AS-Java in your technical system landscape, see Structure linkJava Cluster Architecture and Structure linkBuilding a Cluster Infrastructure with AS-Java in the Architecture Manual. For administration and configuration information, see Structure linkJ2EE Engine Configuration and Structure linkClustering the J2EE Engine in the Administration Manual.
