1 Enterprise Deployment Overview

This chapter provides an overview of the enterprise topology for Oracle Fusion Customer Relationship Management.

This chapter includes the following topics:

1.1 What is an Enterprise Deployment?

An enterprise deployment is an Oracle guidelines blueprint based on proven Oracle high-availability and security technologies and recommendations for Oracle Fusion Applications. The guidelines described in these blueprints span all Oracle products across the entire technology stack: Oracle Database, Oracle Fusion Middleware, Oracle Fusion Applications, and Fusion Middleware Control.

An Oracle Fusion Applications enterprise deployment:


This document focuses on enterprise deployments in Linux environments. Enterprise deployments can also be implemented in UNIX and Windows environments.

1.2 About Oracle Fusion Applications

Oracle Fusion Applications are a unified suite of business applications designed to unify personal and enterprise processes. It unifies transactional Oracle SOA Suite and business processes, business intelligence, and collaborative technologies in a seamless user experience. Oracle Fusion Applications can be easily integrated into a service-oriented architecture and made available as software as a service.

Oracle Fusion Applications offer a strong functional value by providing:

Oracle Fusion Applications incorporate best practice business processes, including those from Oracle E-Business Suite, PeopleSoft, Oracle On Demand, JD Edwards, and Siebel.

Oracle Fusion Applications are standards-based, making them highly adaptable. This standards-based technology allows you to respond effectively to change with flexible, modular, user-driven business software that is powered by best-in-class business capabilities built on open standards. Its technology framework includes the following products:

For more information, see the Oracle Fusion Applications Concepts Guide.

1.3 Benefits of Oracle Recommendations

The Oracle Fusion Applications configurations discussed in this guide are designed to ensure security of all invocations, maximize hardware resources, and provide a reliable, standards-compliant system for enterprise computing with a variety of applications.

The security and high-availability benefits of the Oracle Fusion Applications configurations are realized through isolation in firewall zones and replication of software components.

1.3.1 Built-in Security

The enterprise deployment architectures are secure because every functional group of software components is isolated in its own demilitarized zone (DMZ), and all traffic is restricted by protocol and port. The following characteristics ensure security at all needed levels, as well as a high level of standards compliance:

  • Configure external load balancers to redirect all external communication received on port 80 to port 443.


    The Oracle Technology Network ( provides a list of validated load balancers.

  • Communication from external clients does not go beyond the Load Balancing Router (LBR) level.

  • Components are separated in different protection zones: the Oracle Web Tier, application tier, and the data tier. Moreover, Oracle Identity Management (IDM) has its own protection zones like Oracle Web Tier, Applications tier and Data tier

  • No direct communication from the Load Balancing Router to the data tier is allowed.

  • Direct communication between two firewalls at any one time is prohibited.

  • If a communication begins in one firewall zone, it must end in the next firewall zone.

  • Oracle Internet Directory (OID) is isolated in the data tier.

  • All communication between components across protection zones is restricted by port and protocol, according to firewall rules.

1.3.2 High Availability

The enterprise deployment architectures are highly available, because each component or functional group of software components is replicated on a different computer, and configured for component-level high availability.

1.4 Terminology

The following terminology is used in this enterprise deployment guide:
