摘要

我们确定了需求,然后提出了智慧城市平台(scp)的多层架构,该架构基于使用软件定义基础设施(SDI)作为多层计算云运行的基础设施层、提供数据传播的平台层和提供分析服务的商业智能即服务(BIaaS)层,通过开放api支持智慧城市应用程序。多层云支持从传感器/执行器到智能边缘和核心大规模数据中心的端到端资源编排。SDI提供必要的异构资源,包括计算、存储、gpu、可编程硬件、传感器和网络,所有这些资源都通过联邦在单个域中或跨多个域中联合管理。数据传播服务允许个人、组织和公共机构在一个域内或跨域共享实时或历史数据。分析服务通过对支持决策的数据进行操作来提供情报。公共和私有应用程序提供商使用这些服务来创建智慧城市应用程序。我们讨论了我们在加拿大范围内实施和运营多层SDI云和大多伦多地区(GTA)智能交通平台的经验,并介绍了这些平台的扩展,以处理跨多个领域的智能城市应用。在整个过程中,我们描述了拟议的智慧城市平台如何支持可扩展性和智能,以及它如何具有可复制性、可扩展性和互操作性的期望属性。

Smart city platforms on multitier software-defined infrastructure cloud computing
We identify requirements and then propose a multi-layer architecture for smart city platforms (SCPs) based on an infrastructure layer operating as a multi-tier computing cloud using software-defined infrastructure (SDI), a platform layer providing data dissemination, and a Business-Intelligence-as-a-Service (BIaaS) layer offering analytics services to support smart city applications through open APIs. The multitier cloud enables the end-to-end orchestration of resources from sensor/actuator to smart edge and to core massive datacenter. The SDI provides the necessary heterogeneous resources, including computing, storage, GPUs, programmable hardware, sensors and networking, that are all managed jointly within a single domain or across multiple domains through federation. The data dissemination services allow individuals, organizations, and public agencies to share real-time or historical data within a domain or across domains. The analytics services provide intelligence by acting on data in support of decision-making. Public and private application providers use these services to create smart city applications. We discuss our experience implementing and operating a Canada-wide multitier SDI cloud and a Greater Toronto Area (GTA) platform for smart transportation, and we present extensions of these platforms to handle smart city applications across multiple domains. Throughout we describe how the proposed smart city platform supports extensibility and smartness, and how it has the desired attributes of replicability, scalability and interoperability.
