Data integration and fast effective data processing are the primary challenges in today’s high-performance computing systems used for Big Data processing and analysis in practical scenarios. Blockchain (BC) is a hot, modern technology that ensures high security of data processes stored in highly distributed networks and ICT infrastructures. BC enables secure data transfers in distributed systems without the need for all operations and processes in the network to be initiated and monitored by any central authority (system manager). This paper presents the background of a generic architectural model of a BC system and explains the concept behind the consensus models used in BC transactions. Security is the main aspect of all defined operations and BC nodes. The paper presents also specific BC use cases to illustrate the performance of the system in practical scenarios..

In recent years, so-called Infrastructure as a Service (IaaS) clouds have become increasingly popular as a flexible and inexpensive platform for ad-hoc parallel data processing. Major players in the cloud computing space like Amazon EC2 have already recognized this trend and started to create special offers which bundle their compute platform with existing software frameworks for these kinds of applications. However, the data processing frameworks which are currently used in these offers have been designed for static, homogeneous cluster systems and do not support the new features which distinguish the cloud platform. This chapter examines the characteristics of IaaS clouds with special regard to massively-parallel data processing. The author highlights use cases which are currently poorly supported by existing parallel data processing frameworks and explains how a tighter integration between the processing framework and the underlying cloud system can help to lower the monetary processing cost for the cloud customer. As a proof of concept, the author presents the parallel data processing framework Nephele, and compares its cost efficiency against the one of the well-known software Hadoop.


Database technology is highly developed for the many uses that it is employs; although, tomorrow will hold new challenges and demands that it is ill-equipped to accomplish. The rigors and demands of the current Information Age pushes information systems to develop more universal solutions not pre-established on the proprietary demands of capitalistic conceptions. In the Information Age, the ever-increasing need for more data processing capabilities becomes inherent with the times, and with the addition of the Digital Age, it is assumed that increased data processing will continue to be conducted by discrete electronic computing systems and the many forms that they will take. The continued development of more efficient data models, and the database systems designed to leverage them, will become the chariot bringing forth the climax of the current times and the dawning of new endeavors for human curiosity and our willingness to learn and explore ever further into the beyond. Tackling these issues is the direct purpose of the LISA Universal Informationbase System (the LISA Informationbase), to effectively integrate data of diverse variations and in a semi-ubiquitous structure to increase data automation of information content for use by our patrons in a powerful database management technology. Surveyed in this chapter is a review of this driving technology and its applications, covering the NITA Methodology Stage-I, Stage-II, and Stage-III in its developmental process.
