Book Description
Deploy using the JVM's high performance while building your apps in the language you love. This book introduces you to three JRuby deployment strategies that give you the performance and scalability you need, while you use a language designed for rapid development. Explore common deployment scenarios, including consolidating an MRI-based Ruby deployment onto a single JVM process and porting a Rails application to JRuby, getting it into production, and keeping it running. This new edition has new chapters on Puma, performance tuning, and Java integration, and is updated to the latest versions of JRuby 9k, Rails 4, and JDK 8. JRuby is a fast, scalable, and powerful JVM language with all the benefits of a traditional Ruby environment. JRuby deployments have fewer moving parts and consume less memory than traditional Ruby. With this book, you can now use JRuby in the real world to build high-performance, scalable applications. Deploying your apps on the JVM requires some new approaches. Start by creating a JRuby microservice that takes advantage of the JVM's native concurrency. Then use Docker to build a virtual production environment that's a stable, reproducible place to explore JRuby deployment. Next, port an existing Rails application to JRuby, preparing the app to take advantage of the JVM platform--all while keeping everything that's friendly and familiar to Ruby developers. Deploy the Rails app to Docker with a multi-threaded Puma server to Heroku or your own private cloud. Take advantage of powerful Java libraries. See how JRuby fits into the enterprise by switching your app to use TorqueBox, an all-in-one JRuby environment that includes built-in support for messaging, scheduling, and daemons--perfect for handling the big jobs. Finally, take a deep dive into JVM performance tuning and set up a continuous deployment environment with Travis CI. What You Need: To run the examples in this book, you'll need a computer that can run the Java Virtual Machine and a connection to the Internet.

Book Description
Solve difficult service-to-service communication challenges around security, observability, routing, and resilience with an Istio-based service mesh. Istio allows you to define these traffic policies as configuration and enforce them consistently without needing any service-code changes. In Istio in Action you will learn: Why and when to use a service mesh Envoy's role in Istio's service mesh Allowing "North-South" traffic into a mesh Fine-grained traffic routing Make your services robust to network failures Gain observability over your system with telemetry "golden signals" How Istio makes your services secure by default Integrate cloud-native applications with legacy workloads such as in VMs Reduce the operational complexity of your microservices with an Istio-powered service mesh! Istio in Action shows you how to implement this powerful new architecture and move your application-networking concerns to a dedicated infrastructure layer. Non-functional concerns stay separate from your application, so your code is easier to understand, maintain, and adapt regardless of programming language. In this practical guide, you'll go hands-on with the full-featured Istio service mesh to manage microservices communication. Helpful diagrams, example configuration, and examples make it easy to understand how to control routing, secure container applications, and monitor network traffic. Foreword by Eric Brewer. About the technology Offload complex microservice communication layer challenges to Istio! The industry-standard Istio service mesh radically simplifies security, routing, observability, and other service-to-service communication challenges. With Istio, you use a straightforward declarative configuration style to establish application-level network policies. By separating communication from business logic, your services are easier to write, maintain, and modify. About the book Istio in Action teaches you how to implement an Istio-based service mesh that can handle complex routing scenarios, traffic encryption, authorization, and other common network-related tasks. You'll start by defining a basic service mesh and exploring the data plane with Istio’s service proxy, Envoy. Then, you'll dive into core topics like traffic routing and visualization and service-to-service authentication, as you expand your service mesh to workloads on multiple clusters and legacy VMs. What's inside Comprehensive coverage of Istio resources Practical examples to showcase service mesh capabilities Implementation of multi-cluster service meshes How to extend Istio with WebAssembly Traffic routing and observability VM integration into the mesh About the reader For developers, architects, and operations engineers.

Book Description
Today's modern Rails applications have lots of moving parts. Make sure your next production deployment goes smoothly with this hands-on book, which guides you through the entire production process. You'll set up scripts to install and configure all the software your servers need, including your application code. Once you're in production, you'll learn how to set up systems to monitor your application's health, gather metrics so you can stop problems before they start, and fix things when they go wrong.Deploying Rails takes you on a expertly guided tour of the current best practices in Rails deployment and management. You'll find in-depth explanations on effectively running a Rails app by leveraging popular open source tools such as Puppet, Capistrano, and Vagrant. Then you'll go beyond deployment and learn how to use Ganglia and Nagios to monitor your application's health and gather metrics so you can head off problems before they happen.You'll start out by building your own virtual environment by writing scripts to provision a production server with Vagrant and Puppet. Then you'll leverage the popular Rails deployment tool Capistrano to deploy an application into this infrastructure. Once the app is live, you'll monitor your application's health with Nagios, and configure Ganglia to collect system metrics. Finally, you'll see how to keep your data backed up, recover data when things go wrong, tame your log files, and use Puppet to automate everything along the way.Whether you're a Rails developer who wants a better understanding of the needs of a production Rails system, if you're a system administrator who wants to manage a Rails application, or if you're bridging the gap between development and operations, this book will be your roadmap to successful production deployment and maintenance, whether your application has ten users or ten million users.What You Need:The exercises and examples are most suited to a computer running some Unix variant, such as Mac OS X or Linux. But a Windows machine running Linux in a VirtualBox virtual machine is also sufficient. We'll show you how to set up a local virtual machine for your deployments; you won't need a dedicated server to hone your deployment skills. We expect you to have a basic familiarity with the Ruby programming language, the Ruby on Rails framework, and the Unix command line.

Book Description
Three of CouchDB's creators show you how to use this document-oriented database as a standalone application framework or with high-volume, distributed applications. With its simple model for storing, processing, and accessing data, CouchDB is ideal for web applications that handle huge amounts of loosely structured data. That alone would stretch the limits of a relational database, yet CouchDB offers an open source solution that's reliable, scales easily, and responds quickly. CouchDB works with self-contained data that has loose or ad-hoc connections. It's a model that fits many real-world items, such as contacts, invoices, and receipts, but you'll discover that this database can easily handle data of any kind. With this book, you'll learn how to work with CouchDB through its RESTful web interface, and become familiar with key features such as simple document CRUD (create, read, update, delete), advanced MapReduce, deployment tuning, and more. Understand the basics of document-oriented storage and manipulation Interact with CouchDB entirely though HTTP using its RESTful interface Model data as self-contained JSON documents Handle evolving data schemas naturally Query and aggregate data in CouchDB using MapReduce views Replicate data between nodes Tune CouchDB for increased performance and reliability
