This API lets you define network connectivity in order to leverage network capabilities to cloud deployments. Through this practical book, you will build a strong foundational knowledge of Neutron, and will architect and build an OpenStack cloud using advanced networking features. We start with an introduction to OpenStack Neutron and its various components, including virtual switching, routing, FWaaS, VPNaaS, and LBaaS. You'll also get hands-on by installing OpenStack and Neutron and its components, and use agents and plugins to orchestrate network connectivity and build a virtual switching infrastructure. Moving on, you'll get to grips with the HA routing capabilities utilizing VRRP and distributed virtual routers in Neutron. You'll also discover load balancing fundamentals, including the difference between nodes, pools, pool members, and virtual IPs. You'll discover the purpose of security groups and learn how to apply the security concept to your cloud/tenant/instance. Finally, you'll configure virtual private networks that will allow you to avoid the use of SNAT and floating IPs when connecting to remote networks. Style and approach This easy-to-follow guide on networking in OpenStack follows a step-by-step process to installing OpenStack and configuring the base networking components. Each major networking component has a dedicated chapter that will build on your experience gained from prior chapters.

Lesbare, wartbare und zuverlässige Tests entwickelnStubs, Mock-Objekte und automatisierte FrameworksEinsatz von .NET-Tools inkl. NUnit, Rhino Mocks und Typemock Isolator Unit Testing, richtig durchgeführt, kann den Unterschied ausmachen zwischen einem fehlgeschlagenen Projekt und einem erfolgreichen, zwischen einer wartbaren Code-Basis und einer, die niemand freiwillig anpackt, zwischen dem Nach-Hause-Kommen um 2 Uhr nachts oder zum Abendessen, selbst noch kurz vor dem Release-Termin. Roy Osherove führt Sie Schritt für Schritt von einfachen Tests zu Tests, die wartbar, lesbar und zuverlässig sind. Er geht danach auf die Grundlagen des Interaction Testings ein und stellt schließlich bewährte Vorgehensweisen für das Schreiben, das Verwalten und das Warten der Unit Tests in echten Projekten vor. Darüber hinaus werden auch fortgeschrittene Themen behandelt wie Mocks, Stubs und Frameworks wie etwa Typemock Isolator und Rhino Mocks. Sie werden eine Menge zu fortgeschrittenen Testmustern und zur Testorganisation, zum Arbeiten mit Legacy Code und auch zu untestbarem Code erfahren. Und Sie lernen Werkzeuge kennen, die Sie beim Testen von Datenbanken und anderen Technologien brauchen werden. Alle Beispiele sind mit Visual Studio in C# geschrieben, so dass die Beispiele insbesondere für .NET-Entwickler nützlich sind. Aber auch für Programmierer anderer Sprachen wird das Buch von großem Nutzen sein, da die Prinzipien des Unit Testings für andere Sprachen dieselben sind. Roys Blog finden Sie auf ISerializable.com.

Die 17-jährige Apollonia Parker will frei und ungebunden sein. Sie träumt davon, mit ihrem Motorrad Bonnie durch Schottland zu fahren. Allerdings verfügt sie über eine Gabe, die sie besonders hasst: Sie ist wie ihre Mutter eine Muse. Apollonia hat aber keine Lust, sich an einen Künstler zu binden, diesen zu inspirieren und zu hätscheln. Als der junge, äußerst begabte Singer-Songwriter Nick ihr einen Song widmet, verliebt sie sich Hals über Kopf in ihn. Nick ist von Apollonias Fähigkeiten ganz hingerissen. Doch der habgierige Konzernchef Viktor Tyrell ist gegen diese Verbindung. Er will Apollonias Gabe für seine Zwecke nutzen — und setzt die schwarze Muse Velika auf Nick an. Gelingt es Apollonia am Ende, ihren Freund aus deren Fängen zu befreien?
