Overview of this book

Have you ever wondered how Alexa apps are made, how voice-enabled technologies work, or how chatbots function? And why tech giants such as Amazon and Google are investing in voice technologies? A better question is: why should I start developing on these platforms? Hands-On Chatbot Development with Alexa Skills and Amazon Lex covers all features of the Alexa Skills kit with real-world examples that help you develop skills to integrate Echo and chatbots into Facebook, Slack, and Twilio with the Amazon Lex platform. The book starts with teaching you how to set up your local environment and AWS CLI so that you can automate the process of uploading AWS Lambda from your local machine. You will then learn to develop Alexa Skills and Lex chatbots using Lambda functions to control functionality. Once you’ve come to grips with this, you will learn to create increasingly complex chatbots, integrate Amazon S3, and change the way Alexa talks to the user. In the concluding chapters, we shift our focus to Amazon Lex and messaging chatbots. We will explore Alexa, learn about DynamoDB databases, and add cards to user conversations. By the end of this book, you will have explored a full set of technologies that will enable you to create your own voice and messaging chatbots using Amazon.

Getting Started with AWS and Amazon CLI

Amazon Web Services (AWS) is the collection of all the tools and services that Amazon provides for developers in the cloud. There is a huge range of services available, from a server hosting to machine learning, from game streaming to digital marketing. Each of these services has been designed to perform one thing really well, but the biggest benefit is how well each of the services works together.

In this chapter, we will create an AWS account and explore the AWS console. Once we've got our account set up we'll learn about Lambda functions, creating one of our own. This will start out as a very simple Lambda, but we'll increase the functionality as we go through the rest of this book.

The next section of this chapter will talk about the different ways in which we can edit Lambdas and the advantages and disadvantages of each...
