Each chunk is delivered in a day, and each day is a productive one. Each day builds your competency in DevOps. You will be able to take the task you learn every day and apply it to cultivate the DevOps culture. Each chapter presents core concepts and key takeaways about a topic in DevOps and provides a series of hands-on exercises. You will not only learn the importance of basic concepts or practices of DevOps but also how to use different tools to automate application lifecycle management. We will start off by building the foundation of the DevOps concepts. On day two, we will perform Continuous Integration using Jenkins and VSTS both by configuring Maven-based JEE Web Application?. We will also integrate Jenkins and Sonar qube for Static Code Analysis. Further, on day three, we will focus on Docker containers where we will install and configure Docker and also create a Tomcat Container to deploy our Java based web application. On day four, we will create and configure the environment for application deployment in AWS and Microsoft Azure Cloud for which we will use Infrastructure as a Service and Open Source Configuration Management tool Chef. For day five, our focus would be on Continuous Delivery. We will automate application deployment in Docker container using Jenkins Plugin, AWS EC2 using Script, AWS Elastic Beanstalk using Jenkins Plugin, Microsoft Azure VM using script, and Microsoft Azure App Services Using Jenkins. We will also configure Continuous Delivery using VSTS. We will then learn the concept of Automated Testing on day six using Apache JMeter and URL-based tests in VSTS. Further, on day seven, we will explore various ways to automate application lifecycle management using orchestration. We will see how Pipeline can be created in Jenkins and VSTS, so the moment Continuous? Integration is completed successfully, Continuous Delivery will start and application will be deployed. On the final day, our focus would be on Security access to Jenkins and Monitoring of CI resources, and cloud-based resources in AWS and Microsoft Azure Platform as a Service. Style and Approach This book is all about fast and intensive learning. This means we don't waste time in helping readers get started. The new content is basically about filling in with highly-effective examples to build new things, solving problems in newer and unseen ways, and solving real-world examples.

Aber wenn der Code nicht sauber ist, kann er ein Entwicklungsunternehmen in die Knie zwingen. Jedes Jahr gehen unzählige Stunden und beträchtliche Ressourcen verloren, weil Code schlecht geschrieben ist. Aber das muss nicht sein. Mit Clean Code präsentiert Ihnen der bekannte Software-Experte Robert C. Martin ein revolutionäres Paradigma, mit dem er Ihnen aufzeigt, wie Sie guten Code schreiben und schlechten Code überarbeiten. Zusammen mit seinen Kollegen von Object Mentor destilliert er die besten Praktiken der agilen Entwicklung von sauberem Code zu einem einzigartigen Buch. So können Sie sich die Erfahrungswerte der Meister der Software-Entwicklung aneignen, die aus Ihnen einen besseren Programmierer machen werden – anhand konkreter Fallstudien, die im Buch detailliert durchgearbeitet werden. Sie werden in diesem Buch sehr viel Code lesen. Und Sie werden aufgefordert, darüber nachzudenken, was an diesem Code richtig und falsch ist. Noch wichtiger: Sie werden herausgefordert, Ihre professionellen Werte und Ihre Einstellung zu Ihrem Beruf zu überprüfen. Clean Code besteht aus drei Teilen:Der erste Teil beschreibt die Prinzipien, Patterns und Techniken, die zum Schreiben von sauberem Code benötigt werden. Der zweite Teil besteht aus mehreren, zunehmend komplexeren Fallstudien.

Continuous Delivery ermöglicht es, Software viel schneller und mit wesentlich höherer Zuverlässigkeit in Produktion zu bringen, als es bisher möglich war. Grundlage dafür ist eine Continuous-Delivery-Pipeline, die das Ausrollen der Software weitgehend automatisiert und so einen reproduzierbaren, risikoarmen Prozess für die Bereitstellung neuer Releases bietet. Dieses Buch macht Sie mit dem Aufbau einer Continuous-Delivery-Pipeline vertraut und erklärt, welche Technologien Sie dazu einsetzen können. Dabei lernen Sie u.a. folgende Themen kennen: • Infrastruktur-Automatisierung mit Chef, Docker und Vagrant • Automatisierung von Builds und Continuous Integration • Akzeptanztests, Kapazitätstests, exploratives Testen • Einführung von Continuous Delivery im Unternehmen • Continuous Delivery und DevOps • Auswirkungen auf die Softwarearchitektur Als praktisches Beispiel wird ein konkreter Technologie- Stack vorgestellt. Zahlreiche Aufgaben und Vorschläge für weitergehende Experimente laden Sie darüber hinaus zur praktischen Vertiefung des Themas ein. Nach der Lektüre können Sie abschätzen, welche Vorteile Continuous Delivery konkret bietet, und Sie verfügen über das nötige Handwerkszeug, um Continuous Delivery in Ihrem eigenen Arbeitsumfeld zu etablieren. Die Neuauflage wurde in Bezug auf Werkzeuge wie Docker, Jenkins, Graphite und den ELK-Stack aktualisiert. An neuen Themen sind Docker Compose, Docker Machine, Immutable Server, Microservices und die Einführung von Continuous Delivery ohne DevOps hinzugekommen.

grep kurz & gut ist die erste deutschsprachige Befehlsreferenz zu grep, dem machtigen Such- und Filterungswerkzeug unter Unix. Jeder, der sich ausfuhrlich zu den Moglichkeiten, die in grep stecken, informieren mochte, ist mit diesem Buch bestens bedient. Er erfahrt, wie viele alltagliche Aufgaben mit grep ausgefuhrt werden konnen, von der Mail-Filterung uber geschicktes Log-Management bis hin zur Malware-Analyse. Der Befehl grep stellt viele verschiedene Moglichkeiten bereit, Textstrings in einer Datei oder einem Ausgabestream zu finden. Diese Flexibilitat macht grep zu einem machtigen Tool, um das Vorhandensein von Informationen in Dateien zu ermitteln. Im Allgemeinen ist der Befehl grep nur dafur gedacht, Textausgaben oder Textdateien zu durchsuchen. Sie konnen auch Binardateien (oder andere Nicht-Textdateien) durchsuchen, aber das Tool ist in dem Fall eingeschrankt. Tricks zum Durchsuchen von Binardateien mit grep (also die Verwendung von String-Befehlen) werden ebenso in grep kurz & gut aufgezeigt. Sollte der Leser bereits mit der Arbeit mit grep vertraut sein, hilft ihm grep kurz & gut dabei, seine Kenntnisse aufzufrischen und mit grep besonders effizient zu arbeiten. Fur grep-Einsteiger ist das vorliegende Buch eine hervorragende Moglichkeit, grep von Grund auf zu lernen und klug anzuwenden.

Bill ist IT-Manager bei Parts Unlimited. An einem Dienstagmorgen erhält er auf der Fahrt zur Arbeit einen Anruf seines CEO. Die neue IT-Initiative der Firma mit dem Codenamen Projekt Phoenix ist entscheidend für die Zukunft von Parts Unlimited, aber das Projekt hat Budget und Zeitplan massiv überzogen. Der CEO will, dass Bill direkt an ihn berichtet und das ganze Chaos in neunzig Tagen aufräumt, denn sonst wird Bills gesamte Abteilung outgesourct. Mit der Hilfe eines Vorstandsmitglieds und dessen mysteriöser Philosophie der Drei Wege wird Bill klar, dass IT-Arbeit mehr mit dem Fertigungsbereich in einer Fabrik zu tun hat als er sich je vorstellen konnte. Die Zeit drängt: Bill muss dafür sorgen, dass der Arbeitsfluss auch zwischen den Abteilungen deutlich besser läuft und das Business-Funktionalität zuverlässig bereitgestellt wird. Drei Koryphäen der DevOps-Bewegung liefern hier die rasante und unterhaltsame Story, in der sich jeder, der im IT-Bereich arbeitet, wiederfinden wird. Sie erfahren nicht nur, wie Sie Ihre eigene IT-Organisation verbessern können - nach der Lektüre dieses Buchs werden Sie IT auch nie wieder so sehen wie zuvor.

Das Buch ist eine Einführung in JavaScript, die sich auf gute Programmiertechniken konzentriert. Der Autor lehrt den Leser, wie man die Eleganz und Präzision von JavaScript nutzt, um browserbasierte Anwendungen zu schreiben. Das Buch beginnt mit den Grundlagen der Programmierung - Variablen, Kontrollstrukturen, Funktionen und Datenstrukturen -, dann geht es auf komplexere Themen ein, wie die funktionale und objektorientierte Programmierung, reguläre Ausdrücke und Browser-Events. Unterstützt von verständlichen Beispielen wird der Leser rasch die Sprache des Web fließend 'sprechen' können.
