The objective of SOA implementation is to employ sophisticated IT processes that produce continuous, rapid business change outcomes. The aim of this paper is to present current research of the emergence of SOAs considering the trends in urbanization along with the evolution of technology and ubiquitous computing. This paper will explore current trends in development and utilization of Service Oriented Architectures (SOAs) in Smart Cities and propose an SOA framework that will address the challenges of urban planning and development. Advantages of the SOA if we used it for a Smart City Application can be described as the following: Integrate the physical infrastructures of the city such as the transportation sector, utilities, land, and city services, Flexibility, Scalability and Business agility, Easier Testing and Debugging, Reusability, Platform independence, Increased Productivity, SOA enables business decisions to be translated rapidly into technology. Internet of things (IoT) brings unprecedented changes to all contexts of our lives, as they can be informed by smart devices and real-time data. Among the various IoT application settings, e-government seems to be one that can be greatly benefited using IoT, transforming and augmenting public services. 2019 2019 15 31 10.54216/JCIM.000102 https://www.americaspg.com/articleinfo/2/show/816
