The benefits of digitalisation do not lie in the use of new technologies for existing processes, but in organisational changes and new business models. The book highlights the composable enterprise as the guiding principle for successful digital transformation and associated cost reductions and revenue increases. What does it mean? A composable enterprise is organised in a decentralised process-oriented way. This allows the enterprise to react quickly to new situations, develop or change processes and business models. The information systems are based on platform architectures. A paradigm shift to monolithic applications.Sector concepts for industry, consulting and universities show how organisation and application architectures interlock in the composable enterprise.The reader receives inspiration, a foundation and a compass for the digital transformation of a company to the composable enterprise.

This book overviews the drivers behind the smart city vision, describes its dimensions and introduces the reference architecture. It further enumerates and classifies threats targeting the smart city concept, links corresponding attacks, and traces the impact of these threats on operations, society and the environment. This book also introduces analytics-driven situational awareness, provides an overview of the respective solutions and highlights the prevalent limitations of these methods. The research agenda derived from the study emphasizes the demand and challenges for developing holistic approaches to transition these methods to practice equipping the user with extensive knowledge regarding the detected attack instead of a sole indicator of ongoing malicious events. It introduces a cyber-situational awareness framework that can be integrated into smart city operations to provide timely evidence-based insights regarding cyber incidents and respective system responses to assist decision-making. This book targets researchers working in cybersecurity as well as advanced-level computer science students focused on this field. Cybersecurity operators will also find this book useful as a reference guide.

Erfahren Sie mit diesem Buch alles über die angewandte NetzwerktechnikIm privaten Bereich spielt Netzwerktechnik eine eher untergeordnete Rolle. Dabei sorgt sie erst dafür, dass die Kommunikation via Internet funktioniert. Der industrielle Sektor hat die Vorteile des Datenaustauschs mit Hilfe von Netzwerken allmählich erkannt. Doch erst im Rahmen der ¿Industrie 4.0¿ wird laut Valentin Plenk die Datenübertragung in Echtzeit mehr Bedeutung gewinnen. Mit Blick auf diese Entwicklung stellt er in seinem Buch im Sinne der angewandten Netzwerktechnik speziell die höheren Schichten der Netzwerktechnik in den Fokus. Dieses kompakte Lehrbuch zeigt Ihnen anhand von konkreten, in Java ausprogrammierten Beispielen, wie Informationen zwischen Systemen über ein Netzwerk ausgetauscht werden können. Pro Kapitel behandelt dieses Netzwerktechnik-Buch ein bestimmtes Thema. Nach der Einführung in die Grundlagen der Kommunikation geht derAutor zunächst auf Java-Streams, Zeichencodierung sowie die Netzwerkanalyse mit Wireshark ein. Anschließend schenkt Plenk speziell folgenden Datenaustauschformaten sowie Protokollen besonderes Augenmerk:¿ JSON¿ HTML¿ HTTP¿ OPC UA¿ TCP/IP¿ UDP/IPKonkrete Beispiele und Übungen geben Ihnen PraxiseinblickeAuf diese Weise deckt dieses Buch über die angewandte Netzwerktechnik den gesamten Bereich technischer Kommunikation ab, von den Netzwerkprotokollen bis hin zum Versenden von Netzwerktelegrammen. Durch diese breite Themenauswahl bekommen Sie als Leser ein tieferes Verständnis für die typischen Problemstellungen in der Anwendung der Netzwerktechnik. Sie erfahren mehr über die Darstellung von Daten in einem bestimmten Dateiformat und wie Sie Daten mittels Standardprotokollen austauschen können. Zudem lernen Sie, wie Sie eigene, einfache Protokolle auf der Basis von TCP/IP erstellen können. Schwerpunkt des Buches bildet dabei immer die Anwendung von Netzwerken.Mit Hilfe zahlreicher Übungsaufgaben (inklusive Lösungsvorschlägen) sowie Anwendungsbeispielen können Sie Ihren persönlichen Kenntnisstand überprüfen und das Gelernte vertiefen. So sind Sie ideal auf die Praxis vorbereitet. Die zweite Auflage des Buchs ¿Angewandte Netzwerktechnik kompakt¿ wurde um den Themenbereich Webservices ergänzt.

This book provides a comprehensive review and in-depth discussion of the state-of-the-art research literature and propose energy-efficient computation offloading and resources management for mobile edge computing (MEC), covering task offloading, channel allocation, frequency scaling and resource scheduling. Since the task arrival process and channel conditions are stochastic and dynamic, the authors first propose an energy efficient dynamic computing offloading scheme to minimize energy consumption and guarantee end devices' delay performance. To further improve energy efficiency combined with tail energy, the authors present a computation offloading and frequency scaling scheme to jointly deal with the stochastic task allocation and CPU-cycle frequency scaling for minimal energy consumption while guaranteeing the system stability. They also investigate delay-aware and energy-efficient computation offloading in a dynamic MEC system with multiple edge servers, and introduce an end-to-end deep reinforcement learning (DRL) approach to select the best edge server for offloading and allocate the optimal computational resource such that the expected long-term utility is maximized. Finally, the authors study the multi-task computation offloading in multi-access MEC via non-orthogonal multiple access (NOMA) and accounting for the time-varying channel conditions. An online algorithm based on DRL is proposed to efficiently learn the near-optimal offloading solutions.Researchers working in  mobile edge computing, task offloading and resource management, as well as advanced level students in electrical and computer engineering, telecommunications, computer science or other related disciplines will find this book useful as a reference. Professionals working within these related fields will also benefit from this book.
