The modern "data center" is a complex arena, with physical and virtual servers, multiple OS environments, and complex networking that frequently spans multiple locations. The need to simplify has never been greater. Mesos, an innovative open-source cluster management platform, transforms the whole data center into a single pool of compute, memory, and storage resources that can be allocated, automated, and scaled as if working with a single super-computer. Mesos is an ideal environment for deploying containerized applications at scale, and it's generating a huge buzz in the big data world as a saner environment for running Spark and Hadoop. Mesos in Action introduces the Apache Mesos cluster manager and the concept of application-centric infrastructure. It guides readers from their first steps in deploying a highly-available Mesos cluster through deploying applications in production and writing native Mesos frameworks. It will show how to scale to thousands of nodes, while providing resource isolation between processes using Linux and Docker containers. It contains practical techniques for deploying applications using popular key frameworks, including Marathon, Chronos, and Aurora. Along the way, the book dives into Mesos internals, including fault tolerance, slave attributes, and resource scheduling and Mesos administration, including logging, monitoring, framework authorization, and slave recovery. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.

This book is a snapshot of the vision shared by outstanding scientists on the key theoretical and experimental issues in Mesoscopic Physics. Quantum properties of electrons in solid state devices and transport in semiconducting and superconducting low-dimensional systems, are discussed, as well as the basis of quantum computing (entanglement, noise decoherence and read-out). Each chapter collects the material presented at a Varenna School course of last year, by leading experts in the field. The reader gets a flavor, how theorists and experimentalists are paving the way to the physical realization of solid state qubits, the basic units of the new logic and memory elements for quantum processing. He will be surprised in finding that mesoscopic solid state devices, which were invented just yesterday ( think of the Single Electron Transistor, or the Cooper Pair Box) are currently used as charge-sensing applications in the equipment of frontier research laboratories. These devices contribute as probing systems to produce evidence on still unsettled questions in topics like the metal-insulator transition in disordered two dimensional systems, quantum Hall conductance in heterostructures, or Kondo conductance in quantum dots.

An exercise in cultural sociology, Moral Codes and Social Structure in Ancient Greece seeks to explicate the dynamic currents of classical Hellenic ethics and social philosophy by situating those idea-complexes in their socio-historical and intellectual contexts. Central to this enterprise is a comprehensive historical-sociological analysis of the Polis form of social organization, which charts the evolution of its basic institutions, roles, statuses, and class relations. From the Dark Age period of “genesis” on to the Hellenistic era of “eclipse” by the emergent forces of imperial patrimonialism, Polis society promoted and sustained corresponding normative codes which mobilized and channeled the requisite emotive commitments and cognitive judgments for functional proficiency under existing conditions of life. The aristocratic warrior-ethos canonized in the Homeric epics; the civic ideology of equality and justice espoused by reformist lawgivers and poets; the democratization of status honor and martial virtue that attended the shift to hoplite warfare; the philosophical exaltation of the Polis-citizen bond as found in the architectonic visions of Plato and Aristotle; and the subsequent retreat from civic virtues and the interiorization of value articulated by the Skeptics, Epicureans, and Stoics, new age philosophies in a world remade by Alexander’s conquests—these are the key phases in the evolving currents of Hellenic moral discourse, as structurally framed by transformations within the institutional matrix of Polis society.

Working with big data can be complex and challenging, in part because of the multiple analysis frameworks and tools required. Apache Spark is a big data processing framework perfect for analyzing near-real-time streams and discovering historical patterns in batched data sets. But Spark goes much further than other frameworks. By including machine learning and graph processing capabilities, it makes many specialized data processing platforms obsolete. Spark's unified framework and programming model significantly lowers the initial infrastructure investment, and Spark's core abstractions are intuitive for most Scala, Java, and Python developers. Spark in Action teaches readers to use Spark for stream and batch data processing. It starts with an introduction to the Spark architecture and ecosystem followed by a taste of Spark's command line interface. Readers then discover the most fundamental concepts and abstractions of Spark, particularly Resilient Distributed Datasets (RDDs) and the basic data transformations that RDDs provide. The first part of the book covers writing Spark applications using the the core APIs. Readers also learn how to work with structured data using Spark SQL, how to process near-real time data with Spark Streaming, how to apply machine learning algorithms with Spark MLlib, how to apply graph algorithms on graph-shaped data using Spark GraphX, and an introduction to Spark clustering. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

Eine Microservices-Architektur unterteilt Software-Systeme in eine Vielzahl kleiner Dienste, die unabhängig voneinander in Produktion gebracht werden können. Jedes Team arbeitet dabei an seinen Microservices und ist weitgehend entkoppelt von anderen Teams; das erlaubt eine einfache Skalierung agiler Prozesse. Die Aufteilung in Microservices schützt gegen den Verfall der Architektur, sodass die Systeme auch langfristig wartbar bleiben. Zudem können Legacy-Systeme durch Microservices ergänzt werden, ohne dabei den alten Code zu ändern. Und auch Continuous Delivery ist einfacher umsetzbar. Eberhard Wolff bietet Ihnen in diesem Buch eine umfangreiche Einführung in das Thema Microservices. Dabei geht es u.a. um: • Vor- und Nachteile des Microservice-Ansatzes • Microservices vs. SOA • Die übergreifende Architektur von Microservice-Systemen • Die Architektur einzelner Services • Auswirkungen auf Projektorganisation, Betrieb, Testen und Deployment • Nanoservices Das Buch erläutert technologieneutrale Konzepte und Architekturen, die mit verschiedenen Technologien umgesetzt werden können. Als Beispiel für einen konkreten Technologie-Stack wird Java mit Spring Boot, dem Netflix-Stack und Spring Cloud gezeigt. Anhand von vielen Beispielen und konkreten Szenarien lernen Sie, wie Microservices möglichst gewinnbringend genutzt werden können. Außerdem erhalten Sie Anregungen, das Gelernte durch eigene Experimente weiter zu vertiefen.
