Abstract

Use of the serverless paradigm in cloud application development is growing rapidly, primarily driven by its promise to free developers from the responsibility of provisioning, operating, and scaling the underlying infrastructure. However, modern cloud-edge infrastructures are characterized by large numbers of disparate providers, constrained resource devices, platform heterogeneity, infrastructural dynamicity, and the need to orchestrate geographically distributed nodes and devices over public networks. This presents significant management complexity that must be addressed if serverless technologies are to be used in production systems. This position paper introduces COGNIT, a major new European initiative aiming to integrate AI technology into cloud-edge management systems to create a Cognitive Cloud reference framework and associated tools for serverless computing at the edge. COGNIT aims to: 1) support an innovative new serverless paradigm for edge application management and enhanced digital sovereignty for users and developers; 2) enable on-demand deployment of large-scale, highly distributed and self-adaptive serverless environments using existing cloud resources; 3) optimize data placement according to changes in energy efficiency heuristics and application demands and behavior; 4) enable secure and trusted execution of serverless runtimes. We identify and discuss seven research challenges related to the integration of serverless technologies with multi-provider Edge infrastructures and present our vision for how these challenges can be solved. We introduce a high-level view of our reference architecture for serverless cloud-edge continuum systems, and detail four motivating real-world use cases that will be used for validation, drawing from domains within Smart Cities, Agriculture and Environment, Energy, and Cybersecurity.
COGNIT:无服务器和多提供商认知云边缘连续体的挑战和愿景
无服务器范例在云应用程序开发中的使用正在迅速增长,主要是因为它承诺将开发人员从提供、操作和扩展底层基础设施的责任中解放出来。然而,现代云边缘基础设施的特点是大量不同的提供者、受限的资源设备、平台异构性、基础设施动态性,以及需要在公共网络上编排地理上分布的节点和设备。如果要在生产系统中使用无服务器技术,这就带来了必须解决的重大管理复杂性。本意见书介绍了COGNIT,这是一项重要的欧洲新计划,旨在将人工智能技术集成到云边缘管理系统中,为边缘的无服务器计算创建认知云参考框架和相关工具。COGNIT的目标是:1)为边缘应用程序管理和增强用户和开发人员的数字主权提供创新的无服务器范式;2)利用现有云资源,实现大规模、高度分布式、自适应的无服务器环境的按需部署;3)根据能效启发式和应用需求与行为的变化,优化数据放置;4)启用安全可信的无服务器运行时执行。我们确定并讨论了与无服务器技术与多提供商边缘基础设施集成相关的七个研究挑战,并提出了我们如何解决这些挑战的愿景。我们介绍了无服务器云边缘连续系统参考架构的高级视图,并详细介绍了将用于验证的四个激励实际用例,这些用例来自智能城市、农业和环境、能源和网络安全领域。
