Building Blocks of a Transparent IoT Ecosystem

This chapter presents a comprehensive exploration of Internet of Things (IoT) architecture, focusing on its role in enabling end-to-end visibility. It discusses the layered structure of IoT systems – from data generation at the device level to real-time processing and cloud-based analytics. The chapter addresses critical architectural design principles that support scalability, interoperability and security. The IoT architecture has four stages, namely sensors/actuators, internet gateways with a data acquisition system, Edge IT and a data center or cloud. The chapter also introduces key application areas and highlights the transition towards the Everything-as-a-Service model. It emphasizes on the integration of IoT with cloud computing, outlining how cloud platforms facilitate seamless device connectivity, data storage and on-demand service delivery. The chapter concludes by highlighting the security challenges associated with cloud integration and recommending strategies to build resilient and secure IoT ecosystems.
