Security Architecture for Oracle Identity Management
Oracle recommended 3-Tier architecture for Identity Management and Fusion Middleware applications The standard 3 Tier architecture provided by Oracle for Fusion, is Tier 1 being the Web servers facing the Internet, Tier 2 hosting the middleware, i.e. WebLogic infrastructure (Admin Server, Managed Server, Domain) and Tier 3, the Database layer. Below is the Identity Management architecture from Oracle that shows all components in Highly available production environment. Highly available components shown is 2 hosts for each of the components in a cluster - ie 2 OAM server, 2 OIM servers to ensure availability in case one of the host is unavailable.Highly available clusters are preferred for production environments but if you do not have any such requirement then go for a single instance for each component (OAM, OIM, OUD etc). ------------------------------------------------------------------------------------------- INTERNET TIER 1 OHS/Webgate
