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.

Building a Slackbot using Serverless Framework

In the previous section, we learned how to create a very basic chatbot for an airline. In this section, we will explore a different sort of use case where a chatbot would be extremely useful and this time, we're not going to use Lex.

ChatOps is a term that's used when operational tasks are driven from a conversational platform. It is focused on people collaborating around a particular workflow or process, and a bot can often streamline the automation that's involved. Introducing a bot to the platform that you're collaborating on means that you don't have to break out of your working environment and disrupt your thought process to go and gather facts. This means the team can be much more efficient in investigating and resolving the incident at hand.

If development and support teams are centralizing...
