Preface

Welcome to Learning AWS Lambda!

In this book, you will learn how to use Lambda, how to use it in combination with other AWS services, in particular API Gateway Service, but also services such as DynamoDB, which is the database as a service offering by Amazon that is also a pay-per-use utility-based, utility computing-based service, which works very well in the context of our serverless application architecture.

Also, we will look at other Amazon Web Services that work well alongside Lambda. In addition, you will learn how to use the serverless framework to build larger applications to structure your code, to autogenerate boilerplate code that you can use to get started quickly. In this video, we will explore Lambda and you will learn how to build scalable and cost-efficient applications that require nearly no operations once you have built and deployed your application.

So let's get started on this wonderful journey.

What this book covers

Chapter 1, Getting Started with AWS, gives you an introduction to the fundamental concepts of AWS and also explores the AWS web dashboard. You will also learn to create and test your first lambda function as well.

Chapter 2, Exploring the Serverless Framework, teaches you how to use the Serverless Framework to create and test Lambda functions and APIs. You will also try out different approaches for API testing, Lambda testing, and debugging.

Chapter 3,Building a Serverless Application, shows you how to build your first serverless application.

Chapter 4, Programming AWS Lambda with Java, focuses on how to program Lambda using Java. You will also learn how to use Eclipse with the AWS Toolkit plugin.

Chapter 5, Programming AWS Lambda with Python, features how to create Lambda functions from blueprints on the AWS Management Console using Python.

Chapter 6, Programming AWS Lambda with C#, showcases how to create C# Lambda functions and serverless projects with NET Core.

What you need for this book

The only prerequisite for this course is to have basic programming or scripting experience, which will facilitate the understanding of the examples quickly.

In terms of environment, you only need to download the virtual machine that contains the vulnerable target web application and the Python environment with all the necessary libraries. To run a virtual machine, you will need to install VirtualBox from www.virtualbox.org.

Who this book is for

This book is primarily for IT architects and developers who want to build scalable systems and deploy serverless applications with AWS Lambda. No prior knowledge of AWS is necessary.

To get the most out of this book

This book will give you the maximum benefit if you have some theoretical knowledge of AWS services. Additionally, install the following in your system:

• Java version 1.8
• Visual Studio 2015
• Python 2.7.15
