Worldwide governments are actively looking into cloud computing as a means of increasing efficiency of service delivery and reducing infrastructure costs. As a result of introducing cloud computing, interoperability issues arise and yet it is vital for e-government services to be efficiently achieved; this is also a challenge for the South African government. Systems providing e-services in dif...

This paper presents the various secure data sharing techniques in public clouds. A public cloud allows resources such as applications and storage to be accessible to the public over the internet. Due to the benefits of cloud storage, there has been a growing trend to use the public cloud for secure data sharing and storage. The public cloud storage model should solve the critical issue of data ...

Considering the background of cloud manufacturing and cluster supply chain, we build the basic model to assign the orders priority within each capacity. Then, considering the inter-chain horizontal cooperation, the extended model is proposed to parallel allocation of cross-chain orders as the orders exceeding one single-chain’s capacity. Lagrange algorithm is implemented, and the simulation ana...
