 +
 +===== Discussion =====
 +
 +An Application is software that performs functions for users, [[public:99_annexes:annex-b-terms-and-definitions:o:organization|Organizations]], or other systems.
 +
 +An Application includes one or more software components organised to provide a defined capability or set of capabilities. The concept does not prescribe a particular:
 +
 +  * Architecture
 +  * Programming language
 +  * Interface
 +  * Deployment model
 +  * Execution environment
 +  * Infrastructure provider
 +  * Distribution model
 +
 +An Application includes software intended for direct human interaction and software that interacts only with other Applications, services, components, or systems.
 +
 +An Application differs from [[public:99_annexes:annex-b-terms-and-definitions:i:infrastructure|Infrastructure]]. An Application performs functions associated with its defined purpose. Infrastructure provides resources and supporting services that establish its operating environment.

 +===== Definition =====

 +
 +===== Note =====
 +
 +The classification of software as an Application depends on its role within the relevant context.
 +
 +Software treated as Infrastructure in one context may perform the role of an Application in another context. The applicable architecture, scope, and evaluation purpose establish the relevant classification.
 +
 +An Application does not include the Infrastructure solely because the Infrastructure hosts, executes, stores, connects, or manages the Application.
 +
 +===== Example =====
 +
 +A sanctions-screening Application receives transaction data, applies screening rules, and returns screening results.
 +
 +The Application performs the screening function. The compute, storage, networking, operating-system, and orchestration resources supporting its execution form part of its Infrastructure.
