Build reliable, asynchronous, and distributed applications using message queuing and task orchestration capabilities of Amazon Web Services (AWS) Application Integration. This book prepares you to build distributed applications and administrators, and manage queues, workflows, and state machines.
You'll start by reviewing key AWS prerequisite services such as EC2, Lambda, S3, DynamoDB, CloudWatch, and IAM. Simple Queue Service (SQS) and SNS Simple Notification Service (SNS) are then covered to show how applications interact with each other in a reliable and resilient fashion. Next, workflow building with (Simple Workflow Service (SWF) for orchestration of tasks is explained and in the final chapter learn the techniques for building a state using Step Functions, Simple Workflow Service along with Flow Framework.
The book illustrates all the concepts using numerous examples that work with SDK, CLI, and Console. Most of the code examples are in Java, followed by Python and JavaScript.
What You Will Learn

• Understand the important prerequisites of AWS, such as EC2, Lambda, S3, and DynamoDB

Who This Book Is For
AWS developers and software developers proficient in Java, Python and JavaScript.

利用亚马逊网络服务（AWS）应用集成的消息队列和任务协调功能，构建可靠、异步和分布式的应用程序。本书让你准备好构建分布式应用和管理员，并管理队列、工作流和状态机。

你将首先回顾AWS的关键前提服务，如EC2、Lambda、S3、DynamoDB、CloudWatch和IAM。然后介绍简单队列服务（SQS）和SNS简单通知服务（SNS），以显示应用程序如何以可靠和弹性的方式相互作用。接下来，解释了用简单工作流服务（SWF）来协调任务的工作流程，并在最后一章学习了使用步骤函数、简单工作流服务和流程框架来构建状态的技术。

本书通过大量使用SDK、CLI和Console的例子来说明所有的概念。大部分的代码实例是用Java编写的，其次是Python和JavaScript。
