1 Enterprise Deployment Overview

This chapter provides an overview of the enterprise topology for Oracle Identity Management.

This chapter contains the following sections:

Oracle Identity Management presents a comprehensive suite of products for all aspects of identity management.This guide describes reference enterprise topologies for the Oracle Identity Management Infrastructure components of Oracle Fusion Middleware. It also provides detailed instructions and recommendations to create the topologies by following the enterprise deployment guidelines.

Deploying Oracle Identity Management as described in this guide is a prerequisite for deploying Oracle Fusion Applications as described in Oracle Fusion Applications Customer Relationship Management Enterprise Deployment Guide.

1.1 About the Enterprise Deployment Guide

An enterprise deployment is an Oracle best practices blueprint based on proven Oracle high-availability technologies and recommendations for Oracle Fusion Middleware. The high-availability best practices described in this book make up one of several components of high-availability best practices for all Oracle products across the entire technology stack—Oracle Database, Oracle Fusion Middleware, Oracle Applications, Oracle Collaboration Suite, and Oracle Grid Control.

An Oracle Fusion Middleware enterprise deployment:

For more information on high availability practices, see the Oracle Database High Availability page on Oracle Technology Network at:

1.2 Enterprise Deployment Terminology

This section identifies enterprise deployment terminology used in the guide.

1.3 Benefits of Oracle Recommendations

The Oracle Fusion Middleware configurations discussed in this guide are designed to ensure security of all transactions, 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 Middleware configurations are realized through isolation in firewall zones and replication of software components.

This section contains the following topics:

1.3.1 Built-in Security

The Enterprise Deployment architectures are secure because every functional group of software components is isolated in its own 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:

  • All external communication received on port 80 is redirected to port 443.

  • External communication uses the Secure Socket Layer (SSL) secure Web Protocol. This is terminated at the site's load balancer.

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

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

  • Components are separated between DMZs on the web tier, application tier, and the directory tier.

  • Direct communication across 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 is isolated in the directory tier DMZ.

  • Identity Management components are in the application tier DMZ.

  • All communication between components across DMZs 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.
