Pattern overview

The IBM® SOA Policy Gateway Pattern is set of virtual system patterns providing a policy enforcement point and a policy administration point. The policy administration point is provided by virtual system patterns that provision WSRR in a multi-tier architecture, delivering a production and staging environment. The policy enforcement point is provided by the WebSphere® DataPower® appliance in which a domain is created during virtual system pattern deployment.

There are examples of policy in many, if not all Service Orientated Architecture (SOA) environments. Service producers and consumers agree the capabilities, performance, and characteristics of the service during the design phase. To do this, you can use Service Level Definitions (SLDs) and Service Level Agreements (SLAs). This pattern allows you to define policies for SLDs and SLAs in an efficiently administered, defined, governed, and utilized way. Policy types used in this pattern include the following:
The IBM SOA Policy Gateway Pattern pattern contains the following virtual system patterns:
The four virtual system patterns work together to provide a multi-stage services governance environment. The IBM SOA Policy Gateway Pattern also provides the capability to provision multiple DataPower domains configured to the governance environment during the pattern deployment. Combined, the following deployment topologies are provided:

It is possible to manually configure the deployed virtual system pattern to include monitoring with ITCAM for SOA Version 7. This provides the basic monitoring of events and expands policy support to include monitoring policies. Monitoring policies allow event situations to be defined within the Policy Authoring Point (PAP) and be attached to a service definition, allowing the monitor to act when the event situation occurs.
