EmpowerID Enterprise Identity Warehouse — – The Identity Warehouse provides the central identity store for SSO identities and federation to the various on premise and cloud-based applications with which EmpowerID integrates. The Identity Warehouse should be installed onto a high availability SQL cluster to serve as the enterprise identity hub for the EmpowerID system. Mirroring can also be established to facilitate Microsoft SQL's Always-on availability group capability.
EmpowerID Worker Role Servers — – Worker Role servers make up the application tier of the system and are used for back-end processing of system integration processes such as inventory, synchronization, security management, and internal web service processes. The number and specifications of these back-end servers depends on the number and types of applications and integration processes being managed. These servers do not service User Interface requests.
EmpowerID Web Role Servers — – Web Role servers serve as the front-end user interface servers for the Web applications used by users. These servers serve up the Web pages and perform any interactive workflow processing initiated by users. These serves can be installed in an isolated DMZ environment or on the internal LAN. By default, access to all Web resources is strictly through HTTPS. If desired, firewall and load balancing can be configured to allow the HTTPS requests to terminate on a front-end appliance and then pass through as HTTP to the Web servers.
