Conclusion

In this short paper we have described some challenges that must be overcome before cloud computing can transform into Sky computing, which would move us closer to McCarthy’s notion of utility computing. Some of these challenges are purely technical, and are likely achievable. However, to make the economic incentives work, Sky computing requires a group of cloud providers to adopt reciprocal data peering so that jobs can easily migrate within this large and heterogeneous collection of commodity clouds. Our purpose in writing this paper was to identify this as a crucial step in how the cloud market could be organized, and hopefully create momentum towards the vision of a Sky full of computation, rather than isolated clouds.

在这篇短文中，我们描述了一些必须克服的挑战，以便云计算能够转变为Sky计算，这将使我们更接近麦卡锡（McCarthy）所提出的公用计算概念。这些挑战中有一些是纯技术性的，可能是可以实现的。然而，为了使经济激励机制有效，Sky计算需要一组云服务提供商采用互惠数据对等，以便作业能够在这一大规模且异构的商品化云集合中轻松迁移。

我们撰写这篇论文的目的是将这一点识别为云市场组织的关键步骤，并希望为实现一个充满计算的Sky而不是孤立的云的愿景创造动力。
