A Design Pattern provides a scheme for refining the subsystems or components of a software system, or the relationships between them. It describes
commonly recurring structure of communicating components that solves a general design problem within a particular context . Architectural patterns are
similar to software design patterns but have a broader scope. The architectural patterns address various issues in software engineering, such as computer
hardware performance limitations, high availability and minimization of a business risk.
Perimeter Protected Access points to a single Public VIP that terminates the SSL session at the external facing F5 Virtual Server. The back-end interface of F5
from the same session directs traffic to Oracle OHS for reverse proxy which in turns proxies to the internal F5 Virtual Servers configured as Load Balancers
using the F5 LTM module. This design is ideal for split DNS to allow internal to go exclusively through the internal F5 Virtual Server while having external
traffic route through this architectural pattern. The Oracle WebGate is extended to the perimeter network on the F5 using the Access Policy Manager module.
