CSR: Small: Using Burstable Instances for Cost-Efficacy in the Public Cloud: When and How?

公共云提供商正在探索使用资源超额预订来提高其盈利能力。由于航空业的超额预订可以帮助公司销售更多的机票，从而确保航班更满，公共云中的超额预订可以帮助提供商创建和销售更多的虚拟机（实例）。虽然这些实例更便宜，但更难以使用，因为它们的资源能力随时间而变化。该项目的目标是了解这种突发实例-所谓的突发实例是由于其容量的零星或“突发”性质-并帮助租户经济高效地运行其工作负载。 该项目将与行业进行外联，特别是继续与IBM、谷歌和亚马逊进行积极合作。将努力通过学生实习、讲座和研究/教学学分的补充建议，向这些行业合作伙伴传达对供应商侧整合技术的增强。该项目将使计算机科学和工程专业人数不足的少数群体，特别是女研究生参与进来。最后，该项目的工作成果将与开发的代码一起在网络上公开传播，以便于其他各方进行实验复制和验证。令牌桶的变体）。集成这种有效容量的态势感知并将其应用于应用程序编程平台（memcached，Spark和Hadoop）将带来重大挑战，因为这些平台中的多种资源管理策略现在需要共存。最后一组研究贡献将解决与丰富未来的可突发实例相关的新的提供商方面的问题，为租户提供更多的多样性和灵活性，同时考虑到他们对这些实例的更谨慎的使用。将在以下URL创建该项目的网站：http://www.cse.psu.edu/~bhuvan/burstables.html。该网站将包含所有源代码（租户工作负载增强，Apache Mesos或kubernetes中的提供商端增强，用于运行和解释实验的脚本等），数据和文件（技术报告、代码说明、会议论文和期刊）。 在项目结束后，研究人员仍将可获得这些内容。

Public cloud providers are exploring the use of resource overbooking for improving their profitability. As overbooking in the airline industry helps companies sell more tickets and thereby ensure fuller flights, overbooking in the public cloud helps providers create and sell more virtual machines (instances). While such instances are cheaper, they are more difficult to use because their resource capacities vary over time. The goal of this project is to develop an understanding of such burstable instances - so called due to the sporadic or "bursty" nature of their capacities - and help tenants run their workloads cost-effectively. The project will engage in outreach to industry, particularly to continue active collaborations with IBM, Google, and Amazon. Efforts will be made to convey enhancements to provider-side consolidation techniques to these industrial partners via student internships, talks, and complementary proposals for research/teaching credits. The project will involve under-represented minorities in computer science and engineering, particularly women graduate students. Finally, the work-product of the project will be publicly disseminated on the web, together with developed code, to ease experimental reproduction and validation by other parties.The project will develop fundamentally novel methodologies for inferring undisclosed parameters governing resource regulators (e.g., variants of token buckets) for burstable instances. Integrating such situational awareness of effective capacity and employing it in application programming platforms (memcached, Spark, and Hadoop) would pose significant challenges since a plurality of resource management strategies in these platforms will now need to co-exist. A final set of research contributions will address novel provider-side concerns related to enriching future burstable instances with more diversity and flexibility for tenants taking into account their more careful usage of these instances. A website for the project will be created at the following URL: http://www.cse.psu.edu/~bhuvan/burstables.html. This website will contain all source code (tenant workload enhancements, provider-side enhancements in Apache Mesos or kubernetes, scripts for running and interpreting experiments, etc.), data, and documents (technical reports, code descriptions, papers at conferences and journals) resulting from the project. The contents will remain available for researchers well beyond the duration of the project.
