Multi-instance federated deployments

The multi-instance federated deployment framework provides services for inquiry and search transactions to communicate across multiple geographically-distributed InfoSphere® MDM instances.

The multi-instance federated deployment model contains complete application instances from a data-model and services perspective. Each application instance contains a subset of data that is based on a particular criteria, such as LOB or country. An example of this deployment model would be three party domain application instances, one located in Switzerland, one in France (a cluster node) and another in the UK:

• Users in Switzerland can view Swiss, French and UK data.
• Users in the UK and France can view UK and French data, but are not allowed to see Swiss data for legal reasons.

The federated deployment framework uses metadata to describe the physical topology of federated deployment. Metadata consists of federated profiles that contain a collection of federated instances, each with groups of instance attributes.

The multi-instance federated deployment feature provides federation at the services layer. This means that when the federated party search is performed across all the instances in the profile, each individual instance executes party search service. Each party search service includes all the business behavior configured on the service, such as Rules of visibility, behavior and data extensions, and so on.
