OVERVIEW: The adoption of cloud computing in IT systems is driving even greater diversity in network services. The requirements for the networks that support IT systems going cloud include ensuring the level of reliability required to make services available via the network, keeping data as secure as if it were stored in-house even when the siting of data centers has become borderless, and improving the energy efficiency of equipment including that used in data centers and networking facilities. Hitachi is working on the construction of networks that support the use of cloud computing for services that feature a high level of security and reliability and are capable of delivering responsive performance efficiently and with high availability.

Overview: Successfully combining protection of the global environment with prosperous urban lifestyles that are secure and convenient is an important factor in ensuring the sustainability of cities. The social infrastructure that supports such a city is required not only to establish robust safety and security, it also needs to satisfy criteria such as enhancing urban value by overall optimization and reduction of total cost. To achieve this, parts of the social infrastructure like power, transport, and water which have been optimized independently in the past need to be comprehensively redesigned based on considerations such as environmental performance, customer service level, and operation and maintenance costs. This is one of the prerequisites for achieving what Hitachi calls "next-generation smart cities.". Source

OVERVIEW: The analysis and utilization of large amounts of actual operational data collected from equipment and devices have made it practical to realize the possibilities of converging and advancing the control and information systems. An effective approach to analyze and utilize big data efficiently is to determine the events that must be discovered through data analysis to achieve business objectives, and then select the appropriate mathematical analysis algorithms based on available data, thereby building an analysis method. Hitachi has formed a team specializing in data analysis with extensive experience in product manufacturing, maintenance, and operations, while bringing together a tremendous amount of mathematical analysis technology research in order to promote the achievement of social innovation through the utilization of big data.
