The cloud-based smart city is a way to provide resources and data on demand. Two technologies used to build cloud-based smart city, IoT, and cloud computing are explored. Using smart sensors can capture the movement of the environment, humans, and city infrastructure like building maintenance, traffic control, transportation, pollution monitoring. This is possible through IoT. Future movement could be predicted based on present and past data. Cloud computing is used for cloud storage. Using cloud, users can access resources in virtual mode at any time or anywhere. It can be accessed at different locations at the same time through high speed internet. Cloud is managed by a third party. Users don't have any knowledge regarding resource location and data, such as where user data is stored. Users use cloud service in virtual mode. Basically, cloud is a service provider platform that provides resources and data storage facility in a virtual way; users don't need to purchase resources.
TopIntroduction Of Cloud-Based Iot
Cloud computing is a paradigm where all computing resources are available. These are providing to the user when needed, user-pay according to its use. For example: If a user needs 4 GB of storage on the cloud, but it has used only 2GB, then the user pays only for 2GB which is used, the rest 2GB will be released by the user, the user will not pay for unused space. Users can access any resource on-demand from the cloud. Internet is an essential thing, which is required to access cloud service. Without the internet, users cannot get cloud service. “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and comprises five essential characteristics, three service models, and four deployment models.”
The primary cloud computing model is shown below. Servers, storage, applications, and services are accessed via a shared network. They are shared between organizations and accessed by users or applications. The users may be members of the organizations working on-premise, remote workers, customers, or general public members.

Cloud computing (Amoore, 2013) resources are rapidly provisioned and released with minimal management effort or service provider interaction. This means an organization can have more or fewer servers. It depends on the scale of organization stores, applications, or services and can configure the ones it uses to meet its requirements, as and when it wishes to do so, and without significant effort.
IoT stands for the Internet of Things (Angwin, 2013). IoT is a system referred to the interrelated and inter-connected devices or objects, which can transfer data. All IoT devices have one purpose: to collect data and share that data worldwide using wireless internet. Internet is essential for both cloud and IoT.
