#### 3.8.3 Infrastructure as a Service (IaaS)/Cloud Computing  
Infrastructure as a Service (hereinafter referred to as \"IaaS\") is a cloud computing model that allows organizations to rent, manage, and use virtual IT (Information Technology) infrastructure resources over the Internet. This model provides flexibility and efficiency in the use of hardware, software, and network resources without the need to invest in physical facilities and their maintenance. IaaS provides virtualized resources such as virtual servers, storage, and network processes. These resources are managed by the cloud service provider and are accessible over the Internet. Users can customize their resource usage according to their current needs. This means they can easily increase or decrease capacity according to demand, minimizing costs and ensuring sufficient application performance. IaaS services are often billed on a per-use basis, which means organizations only pay for the resources they use. This funding model enables more efficient use of resources and reduces costs. IaaS service providers are responsible for provisioning and managing the infrastructure, which means users do not have to worry about maintenance and updates to the physical hardware. Users have access to a wide range of technologies and tools available in the cloud, including analytics tools, database systems, and development environments [68].  
In summary, Infrastructure as a Service (IaaS) provides organizations with a flexible and scalable solution for managing their IT infrastructure. It helps organizations improve efficiency, reduce costs, and improve the performance of their IT systems.  
In the context of smart cities, infrastructure as a service (IaaS) and cloud computing play a key role in delivering digital services and managing smart infrastructure. The following are some specific aspects of how IaaS and cloud computing support the development of smart cities.  
Cloud computing enables central storage and management of data, which is key to the efficient functioning of smart cities. City authorities can use cloud storage to share and store data on traffic, the environment, public safety, and other aspects of urban life. IaaS enables the implementation of smart e-government solutions, which include lighting management, traffic management, waste management, and other aspects of the urban environment. Cloud computing provides a platform for managing these systems from a central location using data and analytics. Cloud computing provides a flexible and scalable infrastructure for connecting and managing large numbers of Internet of Things devices and sensors. These devices collect data on the state and functioning of urban infrastructure, such as air quality, noise levels, traffic conditions, etc. Cloud computing enables the integration of different systems and applications within smart cities. This ensures better interoperability and the possibility of creating complex solutions that take into account different aspects of urban infrastructure. Cloud computing provides an agile environment for the development,testing, and implementation of new applications and services within smart cities. This enables rapid innovation and contributes to the dynamism and flexibility of smart city projects [69].  
In summary, infrastructure as a service and cloud computing are key elements for the development of smart cities, enabling central management, efficient data management, implementation of intelligent solutions and supporting agile development of new applications and services. These technologies contribute to a better quality of life for citizens and to the sustainable development of urban infrastructure.
