We propose an architecture for offloading processes in applications to support low-performance devices. Almost all applications based on standardized web technologies are compatible with our architecture. We discuss how interfaces should be used properly to offload processes in JavaScript and argue that an interface for offloading should only be used for defining complex processes. We also propose a method for applying our architecture to web applications that use web workers. Our method automatically offloads some worker processes to the cloud. We also compare the processing times achieved with and without our method. Our architecture exhibits good efficacy with regards to the N-Queen problem, although it is influenced by network latency between a device and the cloud.

The use of highly iterative software development methodologies, such as Agile and Lean, have been growing. However, these methodologies do not explicitly provide practices for managing and measuring software quality. This deficiency may prevent software development organizations in critical domains from transforming from traditional development to highly iterative development. These organizations may need to manage quality during development and may desire to compare with the quality of a large number of products produced in the past. In this paper, we focus on the reliability aspects of software quality and discuss the applicability of conventional reliability metrics to iterative development. First, we defined the general process structure in iterative development. Then, we present an associated quality evaluation scheme closely. Our experimental results indicate that traditional quality metrics were applicable to iterative development and that the iterative development achieved maturity sufficient for the commercial release. © 2013 IEEE.

The use of computing resources on network is becoming active in the Internet and private networks. OpenFlow/Software-Defined Networking (SDN) is drawing attention as a method to control network virtualization for the cloud computing services and other carrier services. This paper introduces examples of OpenFlow/SDN technologies applied to commercial cloud services. Various activities to expand coverage over commercial carrier networks are also mentioned.
