Using patterns and the integrated expertise built into virtual application patterns provided by IBM® can help your organization achieve accelerated time to value and higher hardware utilization rates. This IBM Redbooks® Solution Guide can help you gain the agility to meet the demands of business through automatic scaling policies, service level agreements (SLAs), and quality of service (QoS) settings for the virtual application. Also, complicated topologies that used to take months to deploy, can now be deployed within hours using IBM PureApplication™ System. Figure 1 shows the Business Process Manager Virtual Application pattern. The virtual application will handle topology decisions according to SLA and QoS definitions the operator provides at deployment. This leaves the operator to be concerned only about the application level at deployment, because the virtual application handles scaling, application server clustering, and so on.
