#### 4.2.2 Cloud Computing (CC)  
Cloud Computing (CC) is a useful technology, which provides the chance to store, manage, and transmit data through various platforms (desktops, mobile devices, etc.) and applications, as depicted in Figure 5. Depending on their use, the cloud is divided into three main categories: private cloud, public cloud, and hybrid cloud. Private cloud is dedicated for use by a single organization, while the public cloud is open for everyone where the IT services are delivered across the internet. Hybrid cloud merges private and public cloud capabilities. In all cases, a cloud can be used alongside WSN and IoT. In recent years, the development of CC simultaneously with other emerging technologies, such as mobiles and wearable devices, has been keen to introduce novel technological advances affecting sectors such as society, science, and especially healthcare. Moreover, CC technology, as a recently developed trend, tries to achieve the expectations of users in order to manage, store, access, and analyze BD, and the application using them. CC and BD due to their basic features are closely related. Some of the main goals of CC, such as the computing power and the storage resource management, could offer advantages in the use of BD applications. Additionally, there are several solutions for the processing and storage of large-scale data provided by the use of CC. With the use of distributed technology, the management of data like this might be processed effectively from the cloud. Additionally, by using the parallel computing capacity of CC, the efficient collection and analysis of BD can be improved. Thus, it could

As a result, it is a mandatory requirement for any vendor or service provider to provide the need for a robust cloud infrastructure for BD delivery [31]. Specifically, the collected data from wireless sensors, wearables, or other IoT-based devices constitutes a large amount of data that can be considered as BD. Medical wearables on patients or other mobile smart devices such as smartphones generate a huge data set from different types of data which can be stored in remote cloud servers [34]. Thanks to CC, these data can be stored in a remote location, usually, a cloud server, outside of the computer, and can be accessed through an internet service from anywhere [27]. CC regarding the healthcare area could offer the chance of using and accessing healthcare data of the patients to the nursing stuff and the doctors, from everywhere and in any time. Cloud applications perform BDA and train reasoners to detect clinical conditions and apply intelligent decisions support mechanisms with the use of ML, and AI techniques for premium services, such as coaching. Hence, both the IoT environment and the cloud infrastructure of ePRO/eCOA applications are highly critical, since they include sensitive personal healthcare data, contributing to critical processes, such as the medication monitoring procedure [31]. Additionally, several cloud platforms could be used by the medical stuff and the doctors in order to run complicated applications on them, without the additional need of strong hardware systems [34]. In the healthcare area, cloud platforms are usually used in order to calculate genomic, protein, and molecular medicine. According to many reports, CC is only introduced as a replacement technology for the today's computer networks. However, other areas such as health information systems, health information exchange, or image processing and management still appear to be underrepresented. The concept of smart healthcare is regarded to include all those related to the diagnosis activities, treatment, and prevention of human diseases or injuries, as well as clinical research and healthcare management.
