---++ Standard topologies overview

This page describes the Recommended SSE Deployment Topologies for versions 3.x and 4.x. Refer to [[StandardTopologiesOverview][Standard deployment topologies overview]] for high-level description of the standard topologies, how they are categorized and their key characteristics. 

These recommended deployment topologies for the Rational solution for systems and software engineering (SSE) are a subset of the standard SSE deployment topologies. For the rest of the standard topologies, see [[AlternativeSSEDeploymentTopologies][Alternative SSE deployment topologies]]. Within this wiki, additional guidance and best practices will be developed about how to best instantiate these recommended topologies.

---++ Introduction and approach

These recommended topologies were chosen based upon the following criteria:

   1 Those that are most commonly and successfully deployed to date by customers and internally within IBM
   1 Those that are based upon the most commonly available platforms, operating systems and middleware
   1 Those that are based upon technologies that customers, partners and the IBM Rational Field have the most experience with 
   1 Those that are the focus of testing within IBM Rational.

These recommended topologies represent only a few of the many permutations for deploying the Rational solution for SSE. The [[DeploymentInstallingUpgradingAndMigrating][SSE systems requirements]] capture the full set of options for supported deployment permutations. 

These topologies have been defined to capture good deployment patterns, which include additional guidance on building in flexibility, scalability, performance, and support for other non-functional requirements, such as [[HighAvailability][high availability]], [[DisasterRecovery][disaster recovery]], and [[JTSAuthenticationExplained][security]].

---++ (SSE-E1) Enterprise Windows with Oracle and DOORS/DWA

This enterprise topology uses Windows for the server operating systems. It includes DNG as the RM application. The applications are distributed across separate servers and WAS instances. A reverse proxy is used to ensure public URI stability. Oracle is used for the databases and is hosted on a separate server. Finally, licenses are served by a floating license server and Windows Active Directory Server provides the LDAP based user management.

---++ (SSE-D3) Departmental Windows with Oracle

Departmental or small organisation topology, using DNG as RM tool. Uses 3 Windows servers, with Oracle database on its own server, LQE on another server, and all other applications on third server. Uses Microsoft Active Directory as identity management.
