Chapter 17. Event-Driven Model

So far, we have learned a thing or two about serverless and AWS Lambda. We started off by understanding the entire concept behind serverless architecture and, later, dived into the amazing world of serverless computing with AWS Lambda. We learned how to effectively write, develop, package, and test Lambda functions and also picked up on a few best practices and recommendations along the way.

From this chapter onwards, we will be taking a slightly different approach to understand how few core functionalities of Lambda actually work. For example, how do you trigger Lambda functions to execute based on a trigger? That's exactly what this chapter is going to be all about. In this chapter, we will be covering the following topics:

  • What event-driven model is all about
  • Understanding the event-driven model of Lambda along with a few simple event-driven architectures for better understanding
  • Getting started with simple event-driven use cases of Lambda that range from basic...
