Cloud manufacturing is defined as a relationship between the consumer and a flexible array of production services, managed by an intervening architecture that can match service providers to product and manufacturing processes Cloud manufacturing definitions typically make explicit or imply three groups of actors: consumers, who request and use cloud manufacturing processes; application providers, who provide the software to enable the manufacturing cloud and associated ICT, and service providers who provide, own and operate the manufacturing services. Cloud concepts in principle move away from a single, all-powerful, service provider to enable a combination of distributed systems. Ironically, the way in which this is so far implemented in cloud computing is that several major organizations, such as Amazon and Google, own the majority of these servers, so whilst the data is physically distributed, its ownership is not. Also, whereas the transport of data from a remote point to a customer is nearly instantaneous, the transport of products or components re-quires an appropriate and efficient supply chain and logistics network. In this article we look at the work done in the field of cloud and the branches have arisen in recent years. and we look at a work with concept of security in cloud manufacturing system. پرونده مقاله
