Begin building event-driven microservices, including patterns to handle data consistency and resiliency Key Features Explore the benefits and tradeoffs of event-driven architectures with practical examples and use cases Understand synergy with event sourcing, CQRS, and domain-driven development in software architecture Build an end-to-end robust application architecture by the end of the book Book DescriptionEvent-driven architecture in Golang is an approach used to develop applications that shares state changes asynchronously, internally, and externally using messages. EDA applications are better suited at handling situations that need to scale up quickly and the chances of individual component failures are less likely to bring your system crashing down. This is why EDA is a great thing to learn and this book is designed to get you started with the help of step-by-step explanations of essential concepts, practical examples, and more. You’ll begin building event-driven microservices, including patterns to handle data consistency and resiliency. Not only will you learn the patterns behind event-driven microservices but also how to communicate using asynchronous messaging with event streams. You’ll then build an application made of several microservices that communicates using both choreographed and orchestrated messaging. By the end of this book, you’ll be able to build and deploy your own event-driven microservices using asynchronous communication.What you will learn Understand different event-driven patterns and best practices Plan and design your software architecture with ease Track changes and updates effectively using event sourcing Test and deploy your sample software application with ease Monitor and improve the performance of your software architecture Who this book is for This hands-on book is for intermediate-level software architects, or senior software engineers working with Golang and interested in building asynchronous microservices using event sourcing, CQRS, and DDD. Intermediate-level knowledge of the Go syntax and concurrency features is necessary.

Event-Driven Architecture in Golang

Data is at the center of many challenges in system design today. Difficult issues need to be figured out, such as scalability, consistency, reliability, efficiency, and maintainability. In addition, we have an overwhelming variety of tools, including relational databases, NoSQL datastores, stream or batch processors, and message brokers. What are the right choices for your application? How do you make sense of all these buzzwords? In this practical and comprehensive guide, author Martin Kleppmann helps you navigate this diverse landscape by examining the pros and cons of various technologies for processing and storing data. Software keeps changing, but the fundamental principles remain the same. With this book, software engineers and architects will learn how to apply those ideas in practice, and how to make full use of data in modern applications. Peer under the hood of the systems you already use, and learn how to use and operate them more effectively Make informed decisions by identifying the strengths and weaknesses of different tools Navigate the trade-offs around consistency, scalability, fault tolerance, and complexity Understand the distributed systems research upon which modern databases are built Peek behind the scenes of major online services, and learn from their architectures

The Picture of Dorain Gray

A masterpiece of Biblical scope, and the magnum opus of one of America’s most enduring authors, in a deluxe Centennial edition In his journal, Nobel Prize winner John Steinbeck called East of Eden "the first book," and indeed it has the primordial power and simplicity of myth. Set in the rich farmland of California's Salinas Valley, this sprawling and often brutal novel follows the intertwined destinies of two families—the Trasks and the Hamiltons—whose generations helplessly reenact the fall of Adam and Eve and the poisonous rivalry of Cain and Abel. The masterpiece of Steinbeck’s later years, East of Eden is a work in which Steinbeck created his most mesmerizing characters and explored his most enduring themes: the mystery of identity, the inexplicability of love, and the murderous consequences of love's absence. Adapted for the 1955 film directed by Elia Kazan introducing James Dean, and read by thousands as the book that brought Oprah’s Book Club back, East of Eden has remained vitally present in American culture for over half a century. This Centennial edition, specially designed to commemorate one hundred years of Steinbeck, features french flaps and deckle-edged pages. For more than sixty-five years, Penguin has been the leading publisher of classic literature in the English-speaking world. With more than 1,500 titles, Penguin Classics represents a global bookshelf of the best works throughout history and across genres and disciplines.
