What you need for this book

To run all the code in this book, you only need to have the Java Development Kit installed on your machine. You will have to create an AWS account to apply the steps. AWS offers a free tier for new customers that will cover most of the costs of running examples in the book. On the other hand, some services such as CloudSearch and VPC NAT Gateways are not covered by a free tier. Make sure that you visit the pricing documentation of each service used in the book to avoid unnecessary costs.
