IRES Track I: US-Finnish research on sustainable evolution and technical debt management in cloud-native systems

云原生软件设计旨在充分利用云基础设施的优势。云原生系统的开发是复杂的，并且需要许多团队的交互，这些团队通常负责这种系统的各个子集或不同的视角（即，业务）。然而，这些系统的演化管理受到其分散性质和可能单独管理的代码库的挑战。理解这种涉及许多活动部件的系统的整体观点需要开发人员付出巨大的努力来分析整个系统。该研究项目推进了云原生系统分析方面的知识。它为云原生系统引入了进化保护措施，以减少维护工作。该项目结合了动态和静态系统分析的角度到一个全面的系统中间表示导致整体推理。这种表示将使全面的系统评估和自动推理的潜在设计异常。它将包括各种系统方面的交互式可视化，以帮助从业者更好地观察他们的系统，并教育从业者和学生关于这些系统特有的典型设计陷阱。该项目考虑以人为本和技术角度，以实现自动化和专家知识，实现更可持续的系统发展。 在该项目的整个生命周期中，18名美国学生将在芬兰欧卢大学从事国际研究经验，在Davide Taibi和Valentina Lenarduzzi教授的监督下，他们将与美国首席研究员合作。项目成果也将用于吸引未来的学生与STEM和促进大学的研究和课程在软件工程。这个奖项反映了NSF的法定使命，并已被认为是值得通过评估使用基金会的智力价值和更广泛的影响审查标准的支持。

Cloud-native software design aims to fully utilize the benefits of cloud infrastructure. The development of cloud-native systems is complex and requires the interaction of many teams, often responsible for individual subsets of such a system or different perspectives (i.e., operations). However, the evolution management of these systems is challenged by their decentralized nature and possibly separately managed codebases. Understanding the holistic perspective of such systems with many moving parts involved takes herculean efforts for developers to analyze the system as a whole. This research project advances knowledge in cloud-native system analysis. It introduces evolution safeguards to cloud-native systems to reduce maintenance efforts. This project combines dynamic and static system analysis perspectives into a comprehensive system intermediate representation leading to holistic reasoning. Such a representation will enable comprehensive system assessment and automated reasoning about potential design anomalies. It will include interactive visualization of various system aspects to help practitioners better observe their systems holistically and educate practitioners and students about typical design pitfalls specific to these systems. This project considers human-centered and technical perspectives to enable automation and expert knowledge for more sustainable system evolution. Throughout the lifespan of this project, 18 US students will be engaged in international research experience taking place at Oulu University in Finland, under the supervision of Professors Davide Taibi and Valentina Lenarduzzi, who will work in concert with the US Principal Investigator. Project results will also be used to engage prospective students with STEM and promote university research and coursework in software engineering.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
