如今，功能即服务是无服务器云计算中最有前途的概念。它使开发人员能够专注于应用程序开发，而无需任何系统管理工作：FaaS确保资源分配、快速响应时间、可调度性、可伸缩性、弹性和可升级性。5G、物联网和工业4.0的应用也提出了为时间关键型应用开放云边缘计算基础设施的想法，也就是说，人们强烈希望对FaaS等计算系统提出实时要求。然而，多节点系统使实时调度变得非常复杂，因为即使在一个具有多核处理器的计算节点上保证实时任务执行也是具有挑战性的。本文提出了一种适用于多节点集群实时FaaS平台的分区调度系统的解析模型和启发式分区调度算法。提出了设想的实时FaaS平台的体系结构，强调了其优点和对底层网络和节点的要求，并概述了满足这些要求的相关工作。
Today, Function-as-a-Service is the most promising concept of serverless cloud computing. It makes possible for developers to focus on application development without any system management effort: FaaS ensures resource allocation, fast response time, schedulability, scalability, resiliency, and upgrad-ability. Applications of 5G, IoT, and Industry 4.0 raise the idea to open cloud-edge computing infrastructures for time-critical applications too, i.e., there is a strong desire to pose real-time requirements for computing systems like FaaS. However, multinode systems make real-time scheduling significantly complex since guaranteeing real-time task execution is challenging even on one computing node with multi-core processors. In this paper, we present an analytical model and a heuristic partitioning scheduling algorithm for a partitioned scheduling system suitable for real-time FaaS platforms of multi-node clusters. We present the architecture of the envisioned real-time FaaS platform, emphasize its benefits and the requirements for the underlying network and nodes, and survey the related work that could meet these demands.
