CSR: Small: Plug into the SuperCloud

该项目的目标是在不需要拥有底层基础设施的情况下创建安全的计算云（supercloud）。这将允许组织和个人迁移到云计算环境，同时保留对位置和调度的控制。超级云通过将用户从单一提供商中解放出来，使云计算和存储成为一种商品。本提案中描述的研究旨在通过利用嵌套虚拟化来创建超级云，其中虚拟机及其所依赖的网络和存储可以在多个底层和异构云基础设施之间迁移，而无需用户知道提供商的硬件、管理程序或网络，也无需云提供商之间的任何标准化协议。该项目有三个组成部分：1)通过嵌套虚拟化优化和推广对超级云的支持；2)开发Supercloud管理器；3)通过网络和存储抽象增强超级云，允许应用程序跨多个云运行。超级云解决了当前云产品的许多缺点。用户将不再被绑定到特定的提供商；他们可以在提供商之间移动资源，甚至可以构建跨多个提供商的应用程序，以提高性能和健壮性。开源的超级云还将允许学生实验自己的云管理算法，或者将超级云用于研究。事实上，该提案包括将其纳入提议者与一所历史悠久的黑人大学（霍华德大学）合作举办的夏季研讨会，以及康奈尔大学的云课程。

The goal of this project is enable the creation of secure compute clouds (Superclouds) without requiring ownership of the underlying infrastructure. This will allow organizations and individuals to migrate to a cloud computing environment while retaining control over placement and scheduling. Superclouds make cloud computing and storage a commodity by freeing users from single providers.The research described in this proposal aims to create a Supercloud by utilizing nested virtualization, in which a virtual machine, as well as the network and storage it relies on, can be migrated between multiple underlying and heterogeneous cloud infrastructures without its user being aware of the provider's hardware, hypervisor, or networks and without any standardization of protocols between cloud providers. The project has three components: 1) Optimize and generalize support of a Supercloud via nested virtualization; 2) Develop a Supercloud manager; 3) Enhance the Supercloud with network and storage abstractions that allow applications to run across multiple clouds. Superclouds address many of the shortcomings of current cloud offerings. Users will no longer be tied to a particular provider; they can move their resources between providers and can even build applications that span multiple providers for increased performance and robustness. An open-source Supercloud will also allow students to experiment with their own cloud management algorithms, or instrument the Supercloud for study. Indeed, the proposal includes plans to incorporate this into a summer workshop that the proposers have been running in cooperation with a historically black university (Howard) and also into Cornell's cloud course offerings.
