You'll need prior experience of using AWS to be able to understand the key concepts covered in the book, as it focuses on the patterns rather than the basics of using AWS.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Save the file in your ch2 folder as terraform_install.sh."

A block of code is set as follows:

provider "aws" {
region = "us-east-1"
}
resource "aws_codecommit_repository" "cloudpatterns" {
repository_name = "cloudpatternsrepo"
description = "This is a demonstration repository for the AWS Cloud
Patterns book."
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

provider "aws" {
region = "us-east-1"
}
resource "aws_codecommit_repository" "cloudpatterns" {
repository_name = "cloudpatternsrepo"
description = "This is a demonstration repository for the AWS Cloud
Patterns book."
}

Any command-line input or output is written as follows:

git config --global credential.UseHttpPath true
git init

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "You can close the Run window."
