Glossary application A collection of software components associated with a customer account and used to perform a service or user-oriented work on a computer. application controller A component of Tivoli Intelligent Orchestrator that determines the resource requirements of each application. It also identifies trends and peaks in resource use. Each managed application has an associated application controller. application deployment template A combination of the logical deployment template and the network topology template. application topology A model that defines the components of an application and how they interact, independent of their deployment. It can be used with a physical topology of a data center to determine the appropriate installation methodology. approval status An indicator of whether or not a patch is approved for deployment. autodiscovery A type of discovery where a program automatically detects the resources that were not previously known. automatic mode An operating mode in which all deployment requests are automatically generated and approved. This operating mode is for applications or clusters that do not require human review and approval of deployment recommendations. automation package A collection of commands, shell scripts, workflows, logical operations, and Java plug-ins that applies to the operation of a specific type of software component or a physical device. Also referred to as a tc driver. breach probability A prediction, based on arrival rate, of the likelihood that an application or resource pool will exceed the maximum defined CPU utilization. capacity on demand Automatic provisioning capability. Capacity on demand can be enabled for selected applications. cluster A group of application servers that collaborates for the purposes of workload balancing and failover. configuration drift discovery The identification of configuration changes to a data center device made outside of Tivoli Intelligent Orchestrator. For example, if the IP address of a server is manually changed at the server, the change is identified during configuration drift discovery. customer A group or organization that is associated with one or more applications. A customer can be an external organization that accesses a data center, or an internal department within a company. data acquisition engine A component of Tivoli Provisioning Manager that gathers and pre-processes performance metrics from each managed application. data center asset A logical or physical resource in a data center. Examples include servers, switches, load balancers, software, VLANs, security policies, and service level agreements. data center device See data center asset. data center fragment A list of data center model objects required to support an application deployment template. It is a subset of the data center model. © Copyright IBM Corp. 2004, 2006. All rights reserved. 629
