             resources can be accessed, hence the overall architecture is specific to the application,
             not to the individual services that may be required. Moving from production-oriented
             manufacturing to a service-oriented manufacturing as inspired by cloud computing,
             cloud manufacturing, appears to offer further solution to the challenges faced by current
             manufacturing processed. As expected security is the major challenge in any networked
             computer system, as Cloud Manufacturing is highly reliant on networks, there are
             considerable potential security and trust issue that have to be managed and mitigated
             (Atlam et al., 2018; Henzel and Herzwurm, 2018).
                Cloud manufacturing reflects both the concept of “integration of distributed
             resources” and the concept of “distribution of integrated resources” that mirrors NIST’s
             definition of cloud computing. Cloud manufacturing can be defined as a model for
             enabling ubiquitous, convenient, on-demand network access to a shared pool of config-
             urable manufacturing resources (e.g., manufacturing software tools, manufacturing
             equipment, and manufacturing capabilities) that can be rapidly provisioned and released
             with  minimal   management    effort  or  service  provider  interaction.  In  Cloud
             manufacturing, distributed resources are encapsulated into cloud services and managed
             in a centralized way. As clients can use the cloud services according to their
             requirements, they can request services ranging from product design, manufacturing,
             testing, management across a products life cycle.
                It should be noted that the Cloud-based Industrial Internet of Things is a platform
             which allows for the intelligent usage of applications, information, and infrastructure in
             a cost-effective way. While the IIoT and Cloud computing are different from each other,
             their features are almost complementary, as shown in Table 11.2. This complementarity
             is the primary reason why many researchers have proposed their integration
             (Atlam et al., 2018).
