Cloud Computing erfährt insbesondere im Bereich der Logistik seit mehreren Jahren eine zunehmende Bedeutung. So werden immer neue Anwendungsgebiete durch innovative Cloud Services erschlossen. Die zunehmende Spezialisierung und Fokussierung von Unternehmen auf ihre Kernkompetenzen und die Kooperation dieser mit anderen Unternehmen, um einen gemeinsamen, kollaborativen Geschäftsprozess durch Cloud-Services abzubilden und eine entsprechende Mehrwertdienstleistung zu erbringen, stellt die Unternehmen vor die Herausforderung, Daten bei gleichzeitiger Aufrechterhaltung der Privacy miteinander teilen zu müssen. Die vorliegende Arbeit leistet in diesem Forschungsfeld zwei Beiträge. Hierzu wird zunächst eine Sprache und ein Vorgehen zur Modellierung von Privacy-Anforderungen in solchen Geschäftsprozessen erarbeitet. Als zweiter wesentlicher Beitrag ist die erarbeitete Architektur für die Verwaltung und Ausführung eben dieser kollaborativen Geschäftsprozesse unter Aufrechterhaltung der Privacy zu sehen.

Context: In the field of computer science and communication systems, cloud computing plays animportant role in Information and Technology industry, it allows users to start from small and increase resources when there is a demand. AWS (Amazon Web Services) and GCP (Google cloud Platform) are two different cloud platform providers. Many organizations are still relying onstructured databases like MySQL etc. Structured databases cannot handle huge requests and data efficiently when number of requests and data increase. To overcome this problem, the organizations shift to NoSQL unstructured databases like Apache cassandra, Mongo DB etc. Conclusions: From the literature review, I have gained knowledge regarding the cloud computing, problems existed in cloud, which leads to setup this research in evaluating the performance of cassandra on AWS and GCP. The conclusion from the experiment is that as the thread count increases throughput and latency has increased gradually till thread count 600 in both the clouds. By comparing both the clouds throughput values, AWS scales up compare to GCP. GCP scales up, when compared to AWS in terms of latency.  Keywords: Apache Cassandra, AWS, Google Cloud Platform, Cassandra Stress, Throughput, Latency

The high adoption rate of cloud computing technology is changing the strategic, operational and functional aspects of businesses. Though, as cloud computing is seeing massive global investment, the vast concentration of resources and information argues for new sources of vulnerabilities and challenges for the cloud computing adopters. Hence, the cloud computing technology is argued to see its full potential once solid information security is established. There has been a palpable development of theories, guidelines and standards of how to implement, maintain and continually improve a security information management system. The outcome has resulted in recognized standards. However, the comprehensiveness and the complexity to implement, maintain and continually improve a security information management system remain. Therefore, this study aimed to investigate how cloud computing oriented firms succeed with the realization of an information security management system. This was done by identifying frameworks and processes used by cloud computing oriented organizations.

Innovation of new technology and its adoption contributes not only increasing the businessvalues but as well facilities the business growth and agility to an organization. Cloudcomputing provides hiring, renting and provisioning exclusive use of IT services as ondemand,pay-per-use basis via Internet. This emergence technology has shifted the competitiveIT-landscapes by providing a new computational platform for effective, creativeand deliverable business value model. However, many small organizations are reluctantto deploy their IT platform to Cloud due to the diverse adoption barriers cloud suffers.Despite this the promising attributes CC offers such as of IT operational cost reduction,accessibility and instant deployment makes it a vital embarking point to adopt this technologyespecially small and medium base enterprises (SME). Since SMEs are exploringthe possibilities of adopting this technology, it is imperative for them to critically evaluatethe feasibility of this technology for their specific businesses. This paper aims to investigatecloud adoption factors which might pursue pertaining or embarking cloud integrationamong SME’s. An on line web based survey instrument using questionnaires was used toconduct the study. The conclusive findings of the study suggests that Cloud computinghas the potential to transform the existing business operation, increase the business valuesand agility, customer relationship also promote sustainable competitive business edgefor SMEs while reducing the IT capital expenditure investment cost. The findings willassist IT managers/Chief Technology and /or Information Officers(CTO/CIO) representsthe SMEs for considering a possible adoption approach to cloud services.
