Kubernetes in Action

Kubernetes in Action teaches you to use Kubernetes to deploy container-based distributed applications. You'll start with an overview of Docker and Kubernetes before building your first Kubernetes cluster. You'll gradually expand your initial application, adding features and deepening your knowledge of Kubernetes architecture and operation. As you navigate this comprehensive guide, you'll explore high-value topics like monitoring, tuning, and scaling. Kubernetes is Greek for "helmsman," your guide through unknown waters. The Kubernetes container orchestration system safely manages the structure and flow of a distributed application, organizing containers and services for maximum efficiency. Kubernetes serves as an operating system for your clusters, eliminating the need to factor the underlying network and server infrastructure into your designs.

Mastering Kubernetes

This practical guide demystifies Kubernetes and ensures that your clusters are always available, scalable, and up to dateDiscover new features such as autoscaling, rolling updates, resource quotas, and cluster sizeMaster the skills of designing and deploying large clusters on various cloud platforms Who This Book Is For The book is for system administrators and developers who have intermediate level of knowledge with Kubernetes and are now waiting to master its advanced features. You should also have basic networking knowledge. This advanced-level book provides a pathway to master Kubernetes. What You Will Learn Architect a robust Kubernetes cluster for long-time operationDiscover the advantages of running Kubernetes on GCE, AWS, Azure, and bare metalSee the identity model of Kubernetes and options for cluster federationMonitor and troubleshoot Kubernetes clusters and run a highly available KubernetesCreate and configure custom Kubernetes resources and use third-party resources in your automation workflowsDiscover the art of running complex stateful applications in your container environmentDeliver applications as standard packages In Detail Kubernetes is an open source system to automate the deployment, scaling, and management of containerized applications. If you are running more than just a few containers or want automated management of your containers, you need Kubernetes. This book mainly focuses on the advanced management of Kubernetes clusters. It covers problems that arise when you start using container orchestration in production. We start by giving you an overview of the guiding principles in Kubernetes design and show you the best practises in the fields of security, high availability, and cluster federation. You will discover how to run complex stateful microservices on Kubernetes including advanced features as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage back ends. Using real-world use cases, we explain the options for network configuration and provides guidelines on how to set up, operate, and troubleshoot various Kubernetes networking plugins. Finally, we cover custom resource development and utilization in automation and maintenance workflows. By the end of this book, you'll know everything you need to know to go from intermediate to advanced level. Style and approach Delving into the design of the Kubernetes platform, the reader will be exposed to the advanced features and best practices of Kubernetes. This book will be an advanced level book which will provide a pathway to master Kubernetes

Professional Java Development with the Spring Framework

The Spring Framework is a major open source application development framework that makes Java/J2EE(TM) development easier and more productive. This book shows you not only what Spring can do but why, explaining its functionality and motivation to help you use all parts of the framework to develop successful applications.       You will be guided through all the Spring features and see how they form a coherent whole. In turn, this will help you understand the rationale for Spring's approach, when to use Spring, and how to follow best practices. All this is illustrated with a complete sample application. When you finish the book, you will be well equipped to use Spring effectively in everything from simple Web applications to complex enterprise applications.       What you will learn from this book    * The core Inversion of Control container and the concept of Dependency Injection    * Spring's Aspect Oriented Programming (AOP) framework and why AOP is important in J2EE development    * How to use Spring's programmatic and declarative transaction management services effectively    * Ways to access data using Spring's JDBC functionality, iBATIS SQL Maps, Hibernate, and other O/R mapping frameworks    * Spring services for accessing and implementing EJBs    * Spring's remoting framework       Who this book is for       This book is for Java/J2EE architects and developers who want to gain a deeper knowledge of the Spring Framework and use it effectively.       Wrox Professional guides are planned and written by working programmers to meet the real-world needs of programmers, developers, and IT professionals.
