Learn AWS Serverless Computing

By: Scott Patterson

Overview of this book

Serverless computing is a way to run your code without having to provision or manage servers. Amazon Web Services provides serverless services that you can use to build and deploy cloud-native applications. Starting with the basics of AWS Lambda, this book takes you through combining Lambda with other services from AWS, such as Amazon API Gateway, Amazon DynamoDB, and Amazon Step Functions. You’ll learn how to write, run, and test Lambda functions using examples in Node.js, Java, Python, and C# before you move on to developing and deploying serverless APIs efficiently using the Serverless Framework. In the concluding chapters, you’ll discover tips and best practices for leveraging Serverless Framework to increase your development productivity. By the end of this book, you’ll have become well-versed in building, securing, and running serverless applications using Amazon API Gateway and AWS Lambda without having to manage any servers.

Creating Chatbots

Chatbots have become a new digital channel with which customers can engage with a product or service team. They are a form of self-service automation that uses natural language processing to help an organization scale operations and save cost. Chatbots present themselves on social media or other platforms in the same way as you'd send an instant message or interact with a real person. The goal of a chatbot is to understand what you are asking and perform actions that don't require human intervention.

AWS offers an artificial intelligence service called Amazon Lex where you can create and publish your own conversational bots. These bots can send events to AWS Lambda so that you can add business logic and integrations into your own systems.

Some common use cases for chatbots include customer service, IT operations, helpdesks, travel, and finance.
