Shopping Cart Service Model

The managed service provider imports the Shopping Cart service from CA CMDB. The service appears in CA SOI as shown in the following graphic:

This graphic shows the modeled Shopping Cart service, with top-level Web Farm and Database Cluster groups containing CIs with custom propagation.

The Shopping Cart service has the following characteristics:

Logical groups represent the two main resource domains: the web server farm and the database cluster. The groups use aggregate propagation to the service as shown by the letter A on the arrows connecting the CIs.
The CIs in the web server farm and database cluster use custom propagation as shown by the letter C on the arrows connecting the CIs. Each group of CIs has an associated custom propagation policy that specifies the conditions under which to propagate impact to the related CI (LOADBALANCER01) or group (Database Cluster). Custom propagation policy takes into account that if one server in a cluster or web farm fails, this should not have a severe impact on the service, as long as the other servers are running at peak performance.
The managed service provider has created escalation policy that opens a CA Service Desk ticket when a service alert occurs.
CA Application Performance Management and CA Application Configuration Manager track important service-level metrics and compliance information for the service and associated CIs. If necessary, the managed service provider could also create an SLA for the service that tracks performance against service health, quality, risk, or availability.
