IISWC 2021 Characterizing and Mitigating the I/O Scalability Challenges for Serverless Applications (Dataset and Scripts)

As serverless computing paradigm becomes widespread, it is important to understand the I/O performance characteristics on serverless computing platforms. To the best of our knowledge, we provide the first study that analyzes the observed I/O performance characteristics -- some expected and some unexpected findings that reveal the hidden, complex interactions between the application I/O characteristics, the serverless computing platform, and the storage engines. The goal of this analysis is to provide data-driven guidelines to serverless programmers and system designers about the performance trade-offs and pitfalls of serverless I/O.

随着无服务器计算（serverless computing）范式日益普及，明晰无服务器计算平台的I/O性能特征已成为至关重要的研究课题。据我们所知，本研究为首项针对实测I/O性能特征展开系统性分析的工作，其中既包含符合预期的结论，也涵盖了揭示应用I/O特征、无服务器计算平台与存储引擎之间潜藏且复杂交互关系的意外发现。本次分析的核心目标，是为无服务器程序员与系统设计者提供基于数据驱动的指导方案，帮助其掌握无服务器I/O的性能权衡策略与潜在风险陷阱。
