CNS Core: Small: Scaling Coordination for Microservices with Pangaea

设计应用程序的一种日益流行的方法是使用一种体系结构，该体系结构将应用程序的功能拆分为许多不同的微服务。然而，实现存储和更新的微服务仍然具有挑战性，因为构建它们每次都需要解决许多难题：提供容错、处理许多并发操作以及扩展它们可以完成的工作。该建议旨在以一种可以跨许多存储和更新状态的微服务重用的方式解决这些难题。它建立在一种新兴设计的基础上，这种设计使用一台被称为序列器的机器来命令操作进入状态。与更传统的设计相比，序列器可以更好地扩展微服务所做的工作，但也使得容错和并发处理变得更加困难。该建议试图通过找到一种通用的方法来提供容错、抑制并发性和提供更大的可伸缩性，从而解决序列器的缺点。所提出的工作有可能提高基于微服务的系统的性能并缩短开发时间。鉴于基于微服务的系统的流行，这有可能改善许多作为现代生活不可分割部分的应用程序。该项目计划包括开发软件原型和与大型互联网服务公司合作，以增加技术转让的可能性。此外，该项目的研究将由研究生和本科生进行，他们将学习基于微服务的系统如何工作以及如何构建和改进它们。这些技能在未来可能会变得越来越重要。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

An increasingly popular way to design applications is using an architecture that splits out the functionality of an application into many distinct micro-services. It remains challenging, however, to implement micro-services that store and update because building them requires solving many hard problems each time: providing fault tolerance, handling many concurrent operations, and scaling up the work they can do. This proposal aims to solve these hard problems in a way that can be reused across many micro-services that store and update state. It builds on an emerging design that uses a single machine, called a sequencer, to order operations to state. Compared to more traditional designs, sequencers provide better scaling of the work the micro-service does, but make providing fault tolerance and handling concurrency harder. This proposal seeks to address the shortcomings of sequencers by finding a general way to provide fault tolerance, tame concurrency, and provide even greater scaling.The proposed work has the potential to improve the performance and decrease the development time of micro-service-based systems. Given the popularity of micro-service-based systems, this has the potential to improve many applications that are an integral part of modern life. The project plans include developing software prototypes and working with large Internet services to increase the likelihood of technology transfer. In addition, the research in the project will be conducted by graduate students and undergraduate students that will learn how micro-service-based systems work as well as how to build and improve them. Each of these skills is likely to be increasingly important in the future.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.
