为了在竞争激烈的商业领域获得并保持竞争优势，商业云计算平台应不断努力提供新服务并保持竞争力。遗憾的是，业界越来越认识到，云计算平台无法涵盖基础设施、平台和应用等IT层的各个方面。实际上，最终用户的请求几乎是无限的；而云计算平台所拥有的服务无论是服务种类还是服务能力都相对有限。鉴于这一挑战，通过招募云平台中不存在的外部服务来研究弹性云平台。具体来说，通过动态租用互联网上的合格服务来替代云平台内部缺失的服务，弹性云平台几乎可以以外包服务的方式提供无限的能力，例如计算能力、存储能力、应用功能等。最后通过案例评估了该方法的有效性。
To gain and retain competitive advantages in a competitive business arena, a business cloud-computing platform should continuously strive to offer new services and remain competitive. Unfortunately, it becomes more and more recognized by the industry that a cloud-computing platform could not cover all aspects of IT layers engaged in infrastructure, platform and application. In practice, end users’ requests are nearly unlimited; while the services held by a cloud-computing platform is relatively limited, no matter in service category or in service capacity. In view of this challenge, an elastic cloud platform is investigated by recruited outside services that are absent from the cloud platform. Concretely, through dynamically hiring a qualified service on Internet to replace the absent service inside a cloud platform, an elastic cloud platform could nearly provide unlimited capabilities in an outsourcing service way, e.g., computing power, storage, application functions, etc. At last, the validity of the method is evaluated by a case study.
