Shared services in the multisystem environment
Shared services provide a predefined virtual application pattern that is deployed and shared by multiple application deployments in the cloud, including virtual applications, and virtual systems. Shared services are shipped with the product and are included in the IBM® Foundation Pattern.
Shared services are managed in a multisystem environment in much the same way as a single system environment. In a multisystem environment, multi-cloud cloud groups support communication with shared services.
Deployment environments
Shared service deployments to existing private, single-cloud environment profiles containing a single cloud group are supported. In this case, the shared service deployment is in that single-cloud group and associated with that cloud group. All deployments in that cloud group can use that shared service. However, there is no cross cloud group access to that shared service.
The shared service can also be deployed to a multi-cloud environment profile that could contain multiple cloud groups configured across multiple systems. A shared service can have its virtual machines deployed across multiple cloud groups or systems in a highly available manner. All deployments across cloud groups in that environment profile can use that shared service associated at the environment profile level.
Instances deployed to other multi-cloud environment profiles do not normally have access to the shared service. However, the shared service can provide services to other multi-cloud profiles by creating a reference to it in those profiles. For more information about creating references to a multi-cloud environment profile, see the Related tasks section.
Requirements
If you plan to use shared services in a multisystem environment and provide a high-availability shared service, update your shared services to IBM Foundation Pattern Version 2.1.0.0.
