越来越多的商业组织正在将服务应用程序部署到云基础设施上。鉴于基础设施提供商和产品的可用范围，为给定应用程序选择最合适的云资源集是一项具有挑战性的任务。云提供商使用不同的定价结构提供各种格式的资源。在用于指定应用程序需求的术语和用于描述提供程序资源的术语之间存在不匹配。本文提出了一种基于应用需求映射到云基础设施产品的资源分配方法。媒体转码和金融服务的两个特定领域的本体被用来说明如何应用程序的需求可以建模。然后，它示出了如何可以将需求映射到云资源的一般本体描述。资源本体是提供商不可知的，并提供了一个框架，用于在云市场中搜索满足应用程序需求的一组产品。
Increasingly business organisations are deploying service applications onto cloud infrastructures. Given the available range of infrastructure providers and products, it is a challenging task to select the most appropriate set of cloud resources for a given application. Cloud providers offer resources in various formats using different pricing structures. There is a mismatch between the terminology used to specify an application’s requirements and that used to describe provider resources. In this paper, a resource allocation approach based on mapping application requirements onto cloud infrastructure products is proposed. Two domain-specific ontologies for media transcoding and financial services are used to illustrate how application requirements can be modelled. It is then shown how requirements can be mapped onto a general ontological description of cloud resources. The resource ontology is provider-agnostic and provides a framework for searching the cloud market for a set of products that meet an application’s requirements.
