Follow this step-by-step guide for creating a continuous delivery pipeline using all of the new features in Jenkins 2.0 such as Pipeline as a Code, multi-branch pipeline, and more. You will learn three crucial elements for achieving a faster software delivery pipeline: a fungible build/test environment, manageable and reproducible pipelines, and a scalable build/test infrastructure. Pro Continuous Delivery demonstrates how to create a highly available, active/passive Jenkins server using some niche technologies. What You´ll Learn Create a highly available, active/passive Jenkins server using CoreOS and Docker, and using Pacemaker and Corosync Use a Jenkins multi-branch pipeline to automatically perform continuous integration whenever there is a new branch in your source control system Describe your continuous delivery pipeline with Jenkinsfile Host Jenkins server on a cloud solution Run Jenkins inside a container using Docker Discover how the distributed nature of Git and the ´´merge before build´´ feature of Jenkins can be used to implement gated check-in Implement a scalable build farm using Docker and Kubernetes Who This Book Is For You have experience implementing continuous integration and continuous delivery using Jenkins freestyle Jobs and wish to use the new Pipeline as a Code feature introduced in Jenkins 2.0 Your source code is on a Git-like version control system (Git, GitHub, GitLab, etc.) and you wish to leverage the advantages of a multi-branch pipeline in Jenkins Your infrastructure is on a Unix-like platform and you wish to create a scalable, distributed build/test farm using Docker or Kubernetes You are in need of a highly available system for your Jenkins Server using open source tools and technologies

Learn to use NATS and messaging as a solution for communication between services. The NATS project has been around since 2010, but it has become more popular in recent years due to how well it fits into the paradigm of cloud native applications and microservices architectures. It´s fast becoming a very attractive option thanks to its great performance characteristics--a single server can push millions of messages per second--and overall simple design. First you will learn the fundamentals of NATS, such as its design, protocol and the styles of communications it enables, internals of the NATS clients, and how to use the basic API provided by all the official clients. You will also understand how to setup and configure NATS servers using the configuration file. Next you´ll work with real-world projects and see how to develop a production-ready cloud native application using NATS as the control plane over which clients communicate. Finally you´ll learn advanced usage of the NATS clients, such as implementing heartbeats based failure detectors, tracing or collecting multiple responses from a single request. Perhaps you are familiar with REST-style APIs, and want to make the transition into a messaging-based approach instead. Practical NATS is the perfect place to start. What You´ll Learn Use NATS to build applications which use it as the control plane for communication among components Explore the fundamentals of NATS such as how the protocol works under the hood to more advanced communication styles which are possible with the basic building blocks provided by the client Setup, operate, and configure NATS servers, as well as how to troubleshoot common failure scenarios Who This Book Is For Anyone looking for a solution for some of the problems which come along with microservices and cloud native application development, such as service discovery, low latency requests, load balancing, tracing and monitoring for example. Also adopters of NATS who need further help getting started using it. Ideally you should have some familiarity with Go as that is the language of the code examples.
Structured Computer Organization, specifically written for undergraduate students, is a best-selling guide that provides an accessible introduction to computer hardware and architecture. This text will also serve as a useful resource for all computer professionals and engineers who need an overview or introduction to computer architecture. This book takes a modern structured, layered approach to understanding computer systems. It´s highly accessible - and it´s been thoroughly updated to reflect today´s most critical new technologies and the latest developments in computer organization and architecture. Tanenbaum´s renowned writing style and painstaking research make this one of the most accessible and accurate books available, maintaining the author´s popular method of presenting a computer as a series of layers, each one built upon the ones below it, and understandable as a separate entity.
Quasar steht für ´´Qualitätssoftwarearchitektur´´ und fasst zusammen, was das Software-Haus sd&m in den letzten Jahren an Wissen über Softwarearchitektur gesammelt hat. Im Mittelpunkt von Quasar steht das Denken in Komponenten und Schnittstellen. Ein wesentliches Element von Quasar ist die Trennung von Anwendung und Technik: Wie baut man z.B. eine EJB-Anwendung, die vom verwendeten EJB-Server so wenig wie möglich abhängt? Die ersten sieben Kapitel dieses Buches befassen sich mit Softwarearchitektur im Allgemeinen; sie gelten für jede Art von Softwareentwicklung. Im Einzelnen werden behandelt: Klassen und Schnittstellen, Komponenten und Schnittstellen, Softwarekategorien, Fehler und Ausnahmen sowie die Spezifikation von Schnittstellen. Im zweiten Teil geht es um die Architektur von Informationssystemen: Anwendungskern und Anwendungskomponenten, Persistenz und Transaktionen sowie GUI-Architektur. Die Darstellung ist durchweg nahe an der Implementierung; die zahlreichen Programmbeispiele sind in Java formuliert. Das Buch richtet sich an alle, die verstehen wollen, wie man große Systeme aus Komponenten zusammensetzt. ´´Dieses Buch enthält harten Stoff und vermeidet die häufig anzutreffenden wolkigen Ausführungen über Architektur ebenso wie die Beschränkung auf reine Programmiertechnik. Es ist methodisch fundiert und technisch konkret - Softwarearchitektur für die gehobene Praxis.´´ Aus dem Geleitwort von Ernst Denert
Drive Even More Value from Virtualization: Write VMware® Applications that Automate Virtual Infrastructure Management Companies running VMware have already achieved enormous gains through virtualization. The next wave of benefits will come when they reduce the time and effort required to run and manage VMware platforms. The VMware Infrastructure Software Development Kit (VI SDK) includes application programming interfaces (APIs) that allow developers and administrators to do just that. Until now, there has been little documentation for the APIs. In VMware VI and vSphere SDK, software architect Steve Jin demystifies the entire VMware VI and new vSphere SDK and offers detailed, task-based coverage of using the APIs to manage VMware more efficiently and cost-effectively. Jin walks you through using the VI SDK and cloud-computing vSphere SDK to manage ESX servers, ESX clusters, and VirtualCenter servers in any environment
Even if you have little or no knowledge of T-SQL, Beginning T-SQL 2008 will bring you up to intermediate level and teach you best practices along the way. You´ll learn how to write code that will help you to achieve the best-performing applications possible. You´ll find an introduction to databases, normalization, and SQL Server Management Studio. You´ll understand how data is stored in a database and learn how to use at least one of the available tools to get to that data. Each subsequent chapter teaches an aspect of T-SQL, building on the skills learned in previous chapters. Exercises are included in each chapter because the only way to learn T-SQL is to write some code. This book will do more than just give the syntax and examples. It will teach you techniques to help you avoid common errors and create robust and well-performing code. Imparts best practices for writing T-SQL Helps readers avoid common errors Shows how to write scalable code that yields good performance
