Evolutionary Architecture for Smart City

Smart cities services use components of both the ICT industry and mobile telecommunications industries. This article describes the architectural evolution required to ensure that the rollout and deployment of smart city technologies is smooth through acknowledging and integrating the strengths of both the system architectures proposed.

Here’s the pragmatic framework:

Vertical & Horizontal Architecture for Smart City

Smart cities encompass services in diverse business and technological domains. Presently, most of these services are delivered through domain-specific, tightly coupled systems, which entail limited scalability and extensibility. Such structure is supposed to be transformed into a horizontal architecture through service-delivery platform.

The platform is a new type of platform-as-a-service (PaaS) offering that integrates Internet of Things infrastructure and provides services for application providers to employ IoT and cloud resources on demand.

The service-delivery workflows are presented below. The work flows result in three service-delivery models: virtual verticals, third-party applications, and Internet of Things infrastructure as a service (IoT IaaS).

Seamless Intelligence

Seamless intelligence is a configuration where everything is connected through ubiquitous networks, interfaces, and so on. While similar to previous pervasive and ubiquitous computing scenarios, seamless intelligence has deep roots in technology advancement that didn’t exist in the near past.

With pervasive computing and communication capabilities, information technology will increasingly enhance and augment human knowledge, intelligence, and connectivity. We project that by 2022 society will advance so that intelligence becomes seamless and ubiquitous for those who can afford and use state-of- the-art information technology. We expect this new reality to result from the confluence of multiple information and communication technologies. Computing devices—ranging from wearables, subdermal chips, and the computers inside our mobile devices, laptops, desktops, home servers, TV sets, and refrigerators to the computing cloud we reach via the Internet—will interconnect via different communication and networking technologies. Together, these will form an intelligent mesh: a computing and communication ecosystem that augments reality with information and intelligence gathered from our fingertips, eyes, ears, noses, and brain waves. See Figure 4 for a visual interpretation of this seamless integration.

Five-phase approach (adapting ITIL methodology):

  1. Strategy: Our approach starts by identifying business needs and then defines the service capabilities and parameters necessary to support the business.
  2. Design: The enterprise identifies the necessary services and selects potential service providers. This process includes conventionally provided in-house services, but mainly focuses on external service providers.
  3. Implementation: In service-based IT, implementation includes negotiating and contracting for services, followed by assembly (or integration) of those services.
  4. Operation: The ongoing maintenance of business and technical relationships with service providers helps account for changes in the business and technology landscapes.
  5. Continuous improvement: The final phase is an ongoing effort to manage relationships with service providers to maximize business benefit. Efforts in this phase include assessing risks and devising mitigation strategies to protect against service disruptions or failures.
