Smart Cities Empowered: Leveraging Cloud Computing for IoT Applications

This study takes a closer look at how cloud computing and the Internet of Things (IoT) are coming together to help cities run smarter and more efficiently. As urban areas increasingly rely on IoT devices for managing traffic, conserving energy, and improving public safety, there is a growing need for systems that can handle and process large amounts of data quickly. Cloud computing offers the flexibility and scale to support this, whereas edge computing processes data closer to where it is generated. This is especially important for real-time responses, such as in emergencies or live traffic updates. We explored different cloud IoT frameworks and how artificial intelligence (AI) can support faster and smarter decision-making and improve the quality of urban services. Case studies from real cities have shown clear benefits, including smoother traffic flow, better energy use, cleaner environments, and safer communities. However, these innovations also raise concerns regarding data privacy, cyberattacks, and legal compliance. This study highlights the importance of strong cybersecurity and identifies ongoing challenges, such as latency and system compatibility. To address these issues, we propose the use of decentralized systems and hybrid cloud setups. Looking ahead, AI-powered security and smarter infrastructure will be key to building sustainable and future-ready cities
