Pattern overview

The IBM® SOA Policy Gateway Pattern is set of virtual system patterns that provide a policy enforcement point, a policy administration point, and a policy monitoring point.

You can install the IBM SOA Policy Gateway Pattern on an IBM PureApplication® System appliance on IBM Power® or x86 architectures.

The policy administration point is provided by virtual system patterns that provision WSRR in a multitier architecture, delivering a production and staging environment. The policy enforcement point can be provided by a WebSphere® DataPower® appliance. Alternatively, on x86, your PureApplication System can deploy a virtual DataPower image. In either case, a domain is created during virtual system pattern deployment. The policy monitoring point is provided by a monitoring add-on to the PureApplication System monitoring service.

Possible installations of SOA policy gateway patterns

There are examples of policy in many, if not all Service Oriented Architecture (SOA) environments. Service producers and consumers agree the capabilities, performance, and characteristics of the service during the design phase. To implement these agreements, you can use Service Level Definitions (SLDs) and Service Level Agreements (SLAs). Use the pattern to define policies for SLDs and SLAs in an efficiently administered, defined, and governed way. Policy types that are used in this pattern include the following policies:
The IBM SOA Policy Gateway Pattern contains the following virtual system patterns:

The 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 that are configured to the governance environment during the pattern deployment.
