A solution must exhibit the following five characteristics to be considered a true cloud solution [331]: On-demand self-service: Cloud computing resources can be provisioned without human interaction from the service provider.Broad network access: Cloud computing resources are available over the network and can be accessed by diverse customer platforms.Resource pooling: Cloud computing resources are designed to support a multi-tenant model. Multi-tenancy allows multiple customers to share the same applications or the same physical infrastructure while retaining privacy and security over their information.Rapid elasticity: Cloud computing resources can scale up or down rapidly and, in some cases, automatically, in response to business demands.Measured service: Cloud computing resources usage is metered and manufacturing organisations pay accordingly for what they have used.

Cloud computing technology allows software providers to sell their software to more customers than with traditional software deployment methods. With an economy of scale reaped by service providers, consumers are also able to pay a lower price for the service. With the growing popularity of cloud hosting, application developers and software vendors have been favoring multi-tenanted over traditional single-tenanted cloud service architectures. Multi-tenancy is an architecture style where multiple clients use a single cloud application instance. Different service architectures isolate tenant’s data to a varying degree. At the same time, a service architecture must accommodate the highest possible degree of service variability to allow a service provider to offer a cloud service to tenants with a wide range of varying requirements for service functionality. This case study describes formalized evaluation of profitability of cloud service offering strategies.
Green Cloud Computing

Cloud computing faces several challenging issues related to security, load balancing, quality of service, standardization, and energy consumption. Perhaps the biggest challenge to GCC is related to security. Security is an important factor enabling GCC infrastructure to be deployed. Security issues include sensitive data access, privacy, data recovery, and multi-tenancy issues. Customers should be able to trust that cloud service providers will not misuse their sensitive data [18]. Energy consumption is another main obstacle to GCC. Load balancing in achieving GCC is another challenge. Load balancing is required to distribute the dynamic workload across multiple nodes and avoid overwhelming single node while other nodes are idle [21]. Another limitation is the high cost of purchase of components that are required to make the cloud computing more efficient (such as cooling equipment). The maintenance of the devices included in data centers is also a major concern.

The prognostic process in industrial maintenance is a main step to predict failure in machinery. In order to estimate the RUL for a machine before a failure, many works in PHM domain have shown that to realize a reliable estimation, the necessity of: An ubiquitous access and the maintenance availability at any time and everywhere.A big infrastructure for running solutions and big memory space for storage data.The communication between factories who have many distributed sites and sharing the experiences that can be easily reused by other industrial users who have similar needs.Multi-tenant application, an architecture where a single application instance will serve multiple clients (tenants), to reduce maintenance costs and improve scalability.The security of maintenance’s data and user’s. To satisfy these requirements, we switched to an IT-based solution by introducing the cloud computing paradigm. Technological advances and the new ideology, namely X as a Service, brought by the emerging cloud computing paradigm are opening new opportunities to tackle existing hurdles for implementation of PHM systems.

Virtualization is a critical component of the cloud as it allows several clients to use the same physical resource. According to (Wu et al. 2010), the system fits the holdings into several execution environments by creating a virtual instance of the object or tool, such as an operating system framework, servers, network resources, and capacity devices.Multi-tenancy is a multi-tenant environment that allows for sharing resources or applications in an execution context among multiple customers or clients, even if they do not share the same organizational structure.Cloud storage is a component that is protected, administered, and maintained remotely. It made the network system where clients could access the data available.The hypervisor A virtual machine monitor or supervisor is known as a hypervisor. It is an essential virtualization module. It allows running numerous Virtual Machines (VMs) on a single hardware host. As pointed out by (Feng et al. 2010), it supervises and monitors the other operating systems housed in a single physical system.Cloud Networks this component is capable of working in more than a single data center; hundreds of thousands of servers are common in data centers, according to (Feng et al. 2011). A protected infrastructure and cloud networking are necessary for the cloud to manage and construct storage efficiently.
