课程名称：在AWS上构建现代Node.js应用程序 概述：在现代云原生应用开发中，构建可扩展、高可用且完全托管的无服务器架构通常是目标。这意味着您和您的企业需要减少运维负担，更专注于应用程序和业务特定项目，从而在市场上脱颖而出。本课程将介绍如何在AWS上构建一个现代化的无服务器后端。 在AWS上构建全新应用程序与将现有应用程序迁移到AWS是两项不同的任务。当您需要将现有应用程序移动到AWS时，可能首先会考虑使用亚马逊EC2作为虚拟机，或使用Docker容器和容器托管服务，如亚马逊弹性容器服务（ECS）或亚马逊弹性Kubernetes服务（EKS）。虽然这些都是不错的应用托管选项，但大多数情况下仍需关注承载应用程序的基础设施。 《在AWS上构建现代Node.js应用程序》将探索如何使用亚马逊API网关进行无服务器API托管，利用AWS Lambda进行无服务器计算，以及使用亚马逊Cognito实现无服务器身份验证来构建API驱动的应用程序。我们将遵循API驱动的开发过程，首先模拟API的外观。您将全面了解亚马逊API网关的所有功能，它不仅仅用于托管API。 接下来，我们将使用亚马逊Cognito为API添加身份验证。您将了解Cognito的授权流程如何运作，以及如何将其集成到API中。然后，我们将添加一个由API网关触发的Lambda后端，Lambda函数将使用AWS SDK执行各种数据处理任务。您将了解Lambda的不同配置，并学习如何创建和管理Lambda函数。我们的API的一些功能将需要多个Lambda函数按特定顺序执行，类似于工作流，我们将使用AWS步骤函数（Step Functions）创建无服务器工作流。最后，我们将讨论如何使用AWS的功能在每个层级优化您的API。 注意：该课程有三个版本，针对Node.js开发者的“在AWS上构建现代Node.js应用程序”，针对Python开发者的“在AWS上构建现代Python应用程序”，以及针对Java开发者的“在AWS上构建现代Java应用程序”。这些课程在很大程度上是重叠的，通常我们建议您选择专注于您计划用于开发AWS云基础应用程序的SDK的课程。 我们期待您对AWS有基本的了解。您应该熟悉一些概念，例如AWS全球基础设施的基本知识，了解区域和可用区的概念；高层次理解AWS身份和访问管理（IAM），以及它如何用于控制对AWS资源的访问；您还应理解什么是亚马逊EC2实例，什么是亚马逊S3，什么是VPC，以及其他基本的AWS术语。

Description:
In modern cloud native application development, it’s oftentimes the goal to build out serverless architectures that are scalable, are highly available, and are fully managed. This means less operational overhead for you and your business, and more focusing on the applications and business specific projects that differentiate you in your marketplace. In this course, we will be covering how to build a modern, greenfield serverless backend on AWS. Building brand new applications on AWS is a different task than lifting and shifting existing applications into AWS. When you have an existing application that you need to move to AWS, you might first look to using Amazon EC2 as your virtual machines, or maybe you might look into using docker containers and container hosting services like Amazon Elastic Container Service or Amazon Elastic Kubernetes Service. Those are all great application hosting options, but in most cases, they still require you to have some kind of pulse on the underlying infrastructure hosting your application. ` Building Modern Node.js Applications on AWS will explore how to build an API driven application using Amazon API Gateway for serverless API hosting, AWS Lambda for serverless computing, and Amazon Cognito for serverless authentication. We will follow an API driven development process and first mock up what the API will look like. We will cover all the ins and outs of the service Amazon API Gateway, and as you’ll learn- it does a lot more than just hosting an API. Then we will add authentication to the API using Amazon Cognito. You’ll learn about how the authorization flow works with Cognito, and how to build it into your APIs. From there, we will add a Lambda backend that will be triggered by API Gateway. The lambda functions will be using the AWS SDKs to perform various data processing tasks. You’ll learn about the different configurations that exist for Lambda, and we will show you how to create and manage lambda functions. Some of the features of our API will require multiple lambda functions to execute in a specific order, like a workflow, and we will use AWS Step Functions to create a serverless workflow. Finally, we will talk about how to optimize your APIs at every layer using AWS features. Note: There are three versions of this class, "Building Modern Node.js Applications on AWS" for Node.js developers, "Building Modern Python Applications on AWS" for Python developers, and "Building Modern Java Applications on AWS" for Java developers. The courses do for a large part, overlap and in general, we recommend that you take the course that focuses on the SDK you plan to use to develop your AWS Cloud based applications. We expect that you have basic knowledge of AWS already. Some examples of concepts you should be familiar with are: you should know the basics of the AWS Global infrastructure, like what regions and availability zones are. You also should know the at a high-level AWS Identity and Access Management, or IAM, and how it is used to control access to AWS resources. You should also understand what an Amazon EC2 instance is, what Amazon S3 is, what a VPC is, as well as other basic AWS terminology.
