Overview of this book

With this Learning Path, you’ll explore techniques to easily manage applications on the AWS cloud. You’ll begin with an introduction to serverless computing, its advantages, and the fundamentals of AWS. The following chapters will guide you on how to manage multiple accounts by setting up consolidated billing, enhancing your application delivery skills, with the latest AWS services such as CodeCommit, CodeDeploy, and CodePipeline to provide continuous delivery and deployment, while also securing and monitoring your environment's workflow. It’ll also add to your understanding of the services AWS Lambda provides to developers. To refine your skills further, it demonstrates how to design, write, test, monitor, and troubleshoot Lambda functions. By the end of this Learning Path, you’ll be able to create a highly secure, fault-tolerant, and scalable environment for your applications. This Learning Path includes content from the following Packt products: • AWS Administration: The Definitive Guide, Second Edition by Yohan Wadia • AWS Administration Cookbook by Rowan Udell, Lucas Chan • Mastering AWS Lambda by Yohan Wadia, Udita Gupta

Introducing event-driven architectures


Till now we have been working and understanding Lambda using our trusty calculator example code, that simply accepts few parameters and values as inputs, and, when run, provides you with some desired output. What you may not have noticed is that the inputs that we were providing for the code to run were actually part of an event, that would trigger the code into running. Similarly, you can write Lambda functions that get activated or triggered when a particular message or event is generated. This is perhaps one of the biggest reasons why I love Lambda so much and why Lambda is so much better than your traditional EC2 instances! But, before we begin exploring the various triggers and events that Lambda can respond to, let us understand what Event Driven architectures are all about and how are they so useful.

Event-driven architecture (EDA) is basically a software architecture pattern that deals with the generation, detection, consumption, and reaction...
