As communication uses broader bandwidths and communication needs become diversified, a wide variety of equipment is introduced into network infrastructures. In the cloud computing environment, it is essential to support services that frequently occur and the changing requirements. The dynamic reconfiguration technology realizes the network nodes with excellent performance scalability and functional scalability supporting the cloud computing environment. Further, this technology is also applicable to the middlebox virtualization enabling performance scale-out and system optimization.

Big data multiplies and changes every day, and the quantity of data and the required computing/processing capability vary between projects. To process big data efficiently, it is necessary to locate the required ICT resources dynamically and scalably in optimum placement. This paper describes the features and effectiveness of ProgrammableFlow that optimizes computer and network resources dynamically using OpenFlow/Software Defined Network (SDN) technology.

The trend toward reductions in IT investments due to the current economic climate has tended to focus our attention on cloud computing because it does not require initial capital investment. Nevertheless, even in the cloud environment, the needs of business system infrastructures are essentially the same. The WebOTX operational history extends over more than a decade as a service execution platform that can effectively execute business systems. This paper describes its main features of high reliability and operability, together with a description of the function enhancements that are featured in the latest version.

Optimization of IT costs and the "cloud computing service" that is expected to deal quickly and flexibly with changes in future business procedures are currently attracting attention. This paper introduces the requirements of the data center operations management methods that form the foundation for the use by enterprises of cloud services. It also introduces a method of data center implementation using "MasterScope," integrated operations management software provided by NEC. This method is particularly helpful for providing a performance analysis technique that is a key point in supporting the stable provision of services by minimizing system downtime. This paper also introduces the latest technologies for solving issues resulting from "silent faults" that are difficult to solve using traditional technologies.

The information explosion is becoming a real issue, and the amount of information stored on file servers is continuously bloating, making the identification, organization and utilization of information on file servers difficult jobs. The latest version V2.1 of the Information Assessment Tool, a tool for "visualization," "slimming," "activation" and "optimization" of file servers, adopts the InfoFrame DataBooster high-speed data processing engine to deal with large-scale file servers and enable interactive analysis based on high-speed search/aggregation.
